NEWPORT BEACH, CALIFORNIA
EIR/NB 74-047 ENVIRONMENTAL IMPACT REPORT FOR THE NOISE ELEMENT OF
THE NFWPORT BEACH GENERAL PLAN.
this L.I.R. ha(, been prepared pursuant to the requirements of the
C.F.O.A. and the guideline% of the City of Newport Beach. It is
the intent of this report to explore and evaluate the significant
city-wide environmental impacts of the Noise Element of the Newport
Beach General Plan.
The Noise Element provides a survey of the current noise environment
and concludes with a proposed noise control program.
It is intended that this Noise Element satisfy the State requirement
that local General Plans contain a Noise Element (Section 65302 of
the Government Code).
SCOPE OFREPORT
This "project" is not a development project in the normal sense, but
rather a plan for control of noise. As such, there will be no
immediate effect on the physical environment of the City. Therefore,
this E.I.R. discusses the probable long-term environmental impacts
resulting from the adoption and implementation of this Element.
DESCRIPTION OF ENVIRONMENTAL SETTING
The City of Newport Beach is blessed with'a unique geographical
setting, located on the Pacific Ocean and containing Newport Bay.
NOISE CONTROL OBJECTIVES
The proposals contained in the Noise Element are based on the General
Plan Policy report adopted by the City Council on March 13, 1972.
Following is thv policy relating to the Noise Element excerpted from
the Genr,ral Plan Policy report:
"ihe City Id ntify and measure tho chief
sources of noise! and air pollutants within
the community, and their impact upon the
local environment. The -City shall also
encourage and promote the development of a
comprehensive air and noise quality program
City of Newport Beach
•
4 , .1
to ensure adequate regulations and controls
-for the preservation and enhancement of the
environment."
THE ENVIRONMENTAL IMPACT OF THE PROPOSED ACTION
The Noise Element proposes a program of noise control which can only
he beneficial to the future environment.
ANY ADVERSE ENVIRONMENTAL EFFECTS WHICH CANNOT BE AVOIDED IF THE
PROPOSAL IS�IMPLEMENTLU
No adverse environmental effects will result from the adoption of
this Element.
MITIGATION MEASURES PROPOSED TO MINIMIZE THE IMPACT
No mitigation measures can be proposed, since there will be no
adverse environmental impact.
ALTERNATIVES TO THE PROPOSED ACTION
One alternative is simply not to adopt a Noise Element. This would
be in violation of the State Government Code which requires cities
to adopt a Noise Element.
A second alternative would be to adopt a Noise Element which does not
include proposals for a noise control program. This alternative would
result in the adverse impact of uncontrolled noise.
RELATIONSHIP BETWEEN LOCAL SHORT-TERM USES OF MAN'S ENVIRONMENT AND
THE MAINTENANCE AND ENHANCEMENT OF LONG-TERM PRODUCTIVITY
The Noise Element is a long-range plan for noise control.
k
ANY IRREVERSIBLE ENVIRONMENTAL CHANGES WHICH WOULD RE INVOLVED IN
THE PROPOSED ACTION SHOULD IT BE IMPLEMENTED
No irreversible changes will result.
THE GROWTH -INDUCING IMPACT OF THE PROPOSED ACTION
No growth -inducing impact will result.
SUMMARY
The adoption and implementation of the Noise Element will' result in no
adverse environmental effects. Conversely, the adoption and imple-
mentation of this Element will result in envirohmental improvement.

CITY OF NEWPORT BEACH --- DEPARTMENT OF COMMUNITY DEVELOPMENT
TO: R. V. Hogan, Director
FROM: Carl Neuhausen, Advance Planning Administrator
, SUBJECT: Status of the Noise Element
Since the introduction of a mandatory Noise Element under State
planning law, the Staff has investigated several alternative means
for including the new element as part of the City's General Plan.
The Noise Element essentially requires local cities to quantita-
tively measure, analyze and control various noise levels associ-
ated with existing and future transportation facilities, inclitd-'
ing highways, freeways, mass transit systems, and ground/air
facilities. (See attached bill.)
Due to the additional time, equipment and technical expertise
needed to complete the noise studies, I have excluded the first
possible alternative of utilizing the present City Staff. In
reviewing the'various consultant firms which are now under con-
tract to assist in developing the General Plan, the present
scope of their work and/or the background capabilities of each
firm would also preclude them from successfully completing a
Noise Element.
The Staff is now completing investigations'into the probable.
means and costs of utilizing an additional outside consultant
to develop the Noise Element of the Plan. Two leading'acous-
tical consultants have been requested to submit proposals to the
City, including: Paul S. Veneklasen and Associates, Santa Monica,
and Wyie Laboratories, El Segundo. We have asked that each pro-
posal be designed around a three-phase work program which coin-
cides with other studies and programs now underway -as part of
the General Plan. The three phases will include:
Phase I The measurement and analysis of noise levels
associated with existing transportation
facilities.
Phase II The projection and analysis of future noise
levels associated with proposed transporta-
tion facilities.
Phase III The development of a comprehensive.and
quantitative noise ordinance to -.control '
existing and future noise levels.
In view of the existing !noise studies rebated to air•transporta-
tion facilities, both consultants were asked to liMit their
proposals to the study of vehicular traffic and mass transit

systems as outlined under the State law. It appears that
` sufficient data would be made'available from the Parsons
report.and Wilsey -Ham study on noise levels to satisfy the
Sta'te's criteria. For any further studies related to air
traffic, the'estimated time and costs outlined in each pro-
posal would have to be increased accordingly.
The Staff has received a preliminary proposal from Paul S.
Veneklasen and Associates .which estimates the following costs
for the three phases of the noise study program:
Phase I Existing Noise Level Analysis $13,500
Phase II Projected Noise Level Analysis 2,500
Phase III Development of Noise Ordinance 3,000
Total Program Cost $190000
The second proposal from Wyle Laboratories is being completed
by the firm and will be submitted to the City by the end of
April. -
During the present fiscal year, 1971-72,,the City Council had
appropriated $104,000 for various consultant studies in con-
nection with the General Plan Program. The amount of $79,0.00
has now been encumbered either by contract or payment to the
following consultants:
Transportation Consultant $39,.000
Economic Consultant, 25,000
J,
Housing Consultant 10,000
Geologic Consultant 51000
The remaining $25,00.0 has generally been earmarked for matching
funds which would be used in developing the Coastal Element of
the General Plan. A preliminary amount of these funds, esti-
mated to include up to $10,000, will likely be needed in the
coming month to develop various feasibility studies in connection
with the Coastal Element. The remaining amount, $15,000, would
continue to provide a reserve fund for additional studies which
will be necessary to complete this element of the Plan.
With the introduction of the'Noise Element, it appears that addi-
tional 'Funds will likely be needed this coming fiscal year, 1972-73,
to incorporate the.element as part of the General Plan. The Staff
would recommend that a total amount of $20,000 be requested to
complete the necessary work related to the Noise Element.

INTRODUCTION
Urban noise is becoming a serious environmental problem in all
urbanized areas of the United States. We are frequently
subjected to intrusive and offensive sounds from such sources
as: highway vehicles, aircraft, construction equipment, and
the neighbor's lawnmower, air conditioner, or stereo. These
noises produce annoyance, speech interference, sleep dis-
turbance, mental anguish, and, in some cases, adverse physiological
effects. Noise also has an adverse economic effect; in many
noise -impacted areas, property values have fallen drastically.
The Orange County Health Department has stated that noise
levels will increase as the County continues to grow, and
that noise will become a wide -spread health proirlem by the
year 1990, unless steps are taken to control noise and its
impact.
� City of Newport Beach
PURPOSE AND SCOPE
This Element of the Newport Beach General Plan provides a
survey of the current noise environment,indicating the
major contributors to the noise problem, and concludes with a
proposed "noise control program", which includes all practicable
City actions towards reduction of noise and mitigation of its
adverse effects.
Noise is discussed in terms of three different categories of noise
sources.
1) Motor Vehicles
2) Aircraft
3) Stationary Sources
It is intended that this Element satisfy the State requirement
that local General Plans contain a Noise Element. Section 65302
of the Government Code states, in part, that General Plans shall
include:
--
`'A noise element in quantitative, numerical
terms, showing contours of present and
projected noise levels associated with all
existing and proposed major transportation
elements. These include but are not limited
to the following:
-'
1) Highways and freeways,
�2) Ground rapid transit systems,
(3) Ground facilities associated with
all airports operating under a
permit from the State Depart-
ment of Aeronautics.
-
These noise contours may be expressed in
any standard acoustical scale which includes
both the magnitude of noise and frequency of
--
its occurrence. The recommended scale is
sound level A, as measured with A -weighting
network of a standard sound level meter,
with corrections added for the time duration
per eventand the total number fevents
Newportevent
Cit of beach
- 2 -
per 24-hour period.
Noise contours shall be shown in minimum
increments of five decibels and shall be
continued down to 65 db (A). For regions
involving hospitals, rest homes, long-term
medical or mental care, or outdoor recreational
areas, the contours shall be continued down
to 45 db (A).
Conclusions regarding appropriate site or route
selection alternatives or noise impact upon
compatible land uses shall be included in
the general plan.
The state, local, or private agency responsi-
ble for the construction or maintenance
of such transportation facilities shall
provide to the local agency producing the
general plan; a statement of the present
and projected noise levels of the facility,
and any information which was used in the
development of such levels."
Additionally, this Element is intended to further the accomplishment
of the policy on noise and air pollutants contained in the General
Policy Report (Pg. 20, Policy i) adopted March 13, 1972:
"The City shall identify and measure the chief
sources of noise and air pollutants within
the community, and their impact upon the
local environment. The City shall also
encourage and promote the development of a
comprehensive air and noise quality program
to ensure adequate regulations and controls
for the preservation and enhancement of the
environment."

QUANTI-FICATION OF NOISE

as part of their report "Analysis of Highway Traffic Noise in
Newport Beach, California", prepared under contract with the
City of Newport Beach. It is reprinted here in order to assist

Generation of Sound
Sound in the air is generated by forces acting on the air mole-
cules. This may result from a complicated interaction of air
leaving an exhaust pipe or something as simple as a panel
vibrating against the air. Whatever the mechanism, the result
is that at any one instant, the air will be slightly compressed
at one point and will be rarified at another point. This pattern
of pressure disturbance moves through the air as a sound wave.
Figure I presents this concept in the case of the vibrating panel
driven by an eccentric shaft and rod. As the panel moves to the
right, air is compressed and as it moves to the left, air is
decompressed or rarified. This effect continues with time and
a pressure wave is transmitted into the air. Thus, a rare-
faction wave progresses, to the right as a result of the panel
moving to the left. As the panel moves again to the right,
another compressional wave is gener,ated and the distance between
two successive compressional waves is called the wavelength,
!Noise - How Do We Describe It?
Noise is usually defined as unwanted sound. One person's music
may be nothing but noise to another. For example, the sound of
rock music from your teenager's hi-fi may be music to him or her,
but noise to you, if you are trying to converse or relax in an
adjoining room. To describe noise and its effect on people in
a quantitative way, we must include human factors related to the
way we perceive noise. These factors include differences in the.
way our ears hear sounds at different frequencies, whether

the sound contains any irritating "screech" like squeaky chalk
on the blackboard and how long the sound lasts. Applying all
these factors enables us to translate from a physical measurement
of a sound to its value on a subjective, "perceived noise,"
scale.
Acoustic levels that we normally experience are very small
compared to the usual static (or barometric) pressure in the
atmosphere. An acoustic pressure of 1 microbar would be average
for normal conversational speech tones. This pressure is
equal to 1/1 ,000,000 of the .usual barometric pressure of 14.7 psi.
Thus, at a time and place where the atmospheric pressure was
exactly 14.7 psi, the total peak pressure during average speech
would be 14.700021 and the minimum pressure would be 14.699979 psi.
The decibel scale (discussed below) would specify this very small
pressure fluctuation as 74 decibels. At 134 decibels, a sound
level much higher than normal experience, these two pressure
extremes would be 14.721 and 14.679, respectively. In this
example, the acoustic pressures have changed by a factor of 1000
with an insignificant variation in the total atmospheric pressure.
The Decibel
An explanation is in order regarding some basic properties of
any scale for stating the magnitude of a sound. The ear responds
to sound pressure fluctuations with an increased sensory response
for an increase in pressure. The range between the smallest
sound pressure which is sensed by the human ear and the highest
sound pressure physically tolerable covers a ratio of approximately
1,000,000 to I. If we assign the number 1 to the sound pressure
corresponding to the
smallest sound that
we can hear, then the
City
of
Nuvitport
Bt:;cL;h
sound pressure from our voice in quiet conversational tones would
correspond to the number 1,000. A loud voice would be approxi-
mately 30,000, and physical pain would be felt in the ear at
a sound pressure over 1,000,000.
While our brains have no trouble handling the range of sounds
sensed by our ears, it is inconvenient for us to think in terms
of numbers with all these zeros. It becomes more convenient,
therefore, if we base our scale on the number of zeros
--� rather
than the actual number. The logarithm to the base 10 does just
'- this. Thus, we may assign the zero on our scale to the number
we can just hear, since the logarithm of 1 is zero. Our
quiet conversational tones will then be assigned the number 3,
since the logarithm of 1,000 is 3, and the highest g est pressure
mentioned above (1,000,000) would receive the number 6.
All of the numbers assigned -- 1, 3, and 6 -- are equal to the
logarithm of the actual numbers
and the quantity measured in
such a scale is called a level. Engineers and scientists prefer
to work in terms of energy, which is proportional to sound
pressure squared instead of sound pressure. Thus, all the above
numbers for sound pressures must be squared. Making this adjustment,
l squared becomes 1; 1,000 squared becomes 1,000,000; and 1,
000,000
squared becomes 1,000,000,000,000. Fortunately, the logarithm
of a squared number is just two times the logarithm of the
number; so, instead of the level ranging from 0 to 6, it ranges
from 0 to 12. This scale is similar to the famous Richter scale
for measuring earthquake magnitude, which is also logarithmic.
In the fields of electronics and acoustics, the unit on this
scale is called the
Bel in honor of Alexander Graham 8e1]. For
City of Ntmport Bea&
1
convenience, the Bel is divided up into 10 smaller units,
so that the scale of level now extends from 0 to 120 decibels or
tenths of Bels. •
Figure 2 provides an illustration of these concepts for converting
from an inconvenient magnitude scale (linear pressure) to a more
convenient scale of level (logarithmic) with decibels as the
units. Utilizing this basic idea of a level scale, acousticians
have invented a profusion of different kinds of levels
all in
decibels, abbreviated dB. The most common of these is the
"sound pressure level" defined by:
Sound Pressure Level (SPL) = 10 logl0 (p/preference) 2 in dB
Preference is the reference pressure equal to .00002 newtons per
square meter which is the same as 0.000,000,002,9 pounds per
square inch. This reference pressure was chosen as being near
the smallest sound pressure that we can hear. It sets the
location of the zero on our basic SPL scale.

The Frequency Content or Pitch of Noise
While the magnitude of a sound pressure is of primary importance,
its frequency or pitch is also a primary consideration. The
frequency or pitch of a sound represents the rate of oscillations
of the acoustic pressure. The human ear is less sensitive to
low frequency sounds and very high frequency sounds than it is
to mid -frequency sounds. The frequency limits of audible sounds
extend from 20 to 20,000 Hz (cycles per second). The moving
panel of Figure I-1 may move back and forth 20 times or cycles
each second to create a 20 Hz acoustic signal or 1000 times each
second to create a 1000 Hz signal. The lowest note on a
-` moderately large pipe organ will be 32 Hz, and the highest note
from a piccolo will be around 4700 Hz. Overtones from each of
these instruments will extend to beyond audibility. As
mentioned above, however, the ear is not equally sensitive to
all these frequencies. The ear is 50 dB less sensitive at 20 Hz
-- than it is at 1000 Hz. Figure 3 demonstrates the different
sensitivity of the ear at different frequencies and shows how it
affects a given sound spectrum, happily reducing the annoyance
caused by low frequency noise. Figure I-3(b), showing the
allowance for human hearing, has been defined as the "A" weighting
-- scale. Electronic filters having this frequency response have
been incorporated in most sound measuring equipment. When such
filters are used, the resulting reading is said to be "A" weighted
or "A" scale. Use of these filters allows us to determine a
single decibel number which, to some extent, represents human
response to a given noise.
City of Newport Beach
Time Factors in Defining Noise Environments
So far we have talked only about the magnitude and frequency of
noise along with the decibel scale with which we measure the
magnitude. The perceived level (that is - the way our brains
react to it) that we subjectively apply to a noise seems to depend
upon its duration also. In addition, the actual annoying effect
of the sound may depend on the time of day as well. This
time of day sensitivity simply relates to our daily cycle of
activity. In other words, a short loud blast of a whistle
announcing noon (and lunch) would not be found so irritating as
a less intense noise sounding over a period of several hours
during the day. The same short blast, or even the long duration
"less intense noise" might be found quite irritating during the
middle of the night when we are trying to sleep. Thus, in
order to produce a rating scale for the annoying effect of noises
we consider, in addition to the level and frequency content,
the duration of the sound. Further, we attempt, in a crude way,
to account for varying interferences with our daily life. We
therefore consider the time of day during which the noise is
generated.
Sound waves are a form of energy just like electricity and light.
The rate of release of energy or power may be measured in terms
of kilowatts gust as electrical power is. The power associated
with acoustics within our normal experience is quite small
compared with the power available from the electric lines. Where
a very small electric light bulb will use 25 to 30 watts of
electricity, normal conversational speech power will be around

total acoustic energy found at a given point over a one -hour
period divided by the number of seconds in the hour. Again,
the decibel scale is used and it is defined such that the
HNL of a steady tone is the same as the SPL (sound pressure
level).
The end result of all this is just to say that a loud noise
for a short time may receive the same rating as a soft
noise over a long period of time. The same HNL reading would
be obtained if one truck passed by and generated a noise
level of 88 dB for 10 seconds or 78 dB for 100 seconds. If
ten trucks, each making 88 dB for 10 seconds, went by during
the hour, an HNL meter would read 73 dB - a tenfold increase
in noise energy represented by a 10 dB increase in the Hourly
Noise Level. Thus, 100 such trucks would give a reading of 83
dB and 1000 of them would increase the level to 93 dB, and
so forth.
Community Noise Equivalent Level (CNEI._)_
So far in our example, nothing has been said about the time
of day the trucks were going by. The time -integrated measure
of noise which attempts to account for this time of day
sensitivity is called the Community Noise Equivalent Level.
It is developed in the following way. Early studies of
community noise exposure indicated that one intruding sound
during the evening hours will be approximately as annoying
as three occurrences of the same sound during the day. During
sleeping hours at night, this time -of -day penalty seems to
be about 10. The factors of 3 and 10 are only approximate, but
they seem to give
a reasonable accounting of the weighting that
city
of
New-Hort
Beach
should be applied for evening and nighttime noises. The times
--
have been customarily specified for daytime, evening and night-
time and are 7:00 a.m. to 7.00 p.m., 7.00 p.m. to 10.00 p.m.
and 10:00 p.m. to 7:00 a.m. respectively. Therefore, if 33
trucks by during the hours, they be
passed evening would counted
as 100 trucks and given the same effective HNL value of 83
dB as the 100 trucks during the daytime hours (add 5 dB for
three times as many and 10 dB for 10 times as many). During
nighttime hours, only 10 trucks would be counted as
equivalent to 100 trucks and would yield the same HNL effective
value of 83 dB. Thus, the noise energy is defined in terms
of the dourly Noise Level for each hour of the day. This
energy for each hour over the entire day, after having been
appropriately weighted to account for the time of day as
above, would be added together and divided by 24 to give the
weighted average noise level for the day. When expressed
in decibel form, this number is called the Community Noise
Equivalent Level (CNEL). It provides a single number to
'^
show the relative noisiness of a given location on a given day.
Generally, this number does not vary substantially at a given
community location over a period of weeks. In areas where
there are large variations in seasonal: traffic, there will be
seasonal variations in the CNEL. When the CNEL is dominated
~~
by highway traffic, as it often is, the traffic must double
to effect a 3 dB change in the CNEL. An annual average of
the daily CNELs for a given area would tend to exhibit little
change from year to year, providing the nearby land use and
traffic flow do not change markedly.
City of Newport Beach
watts into a loudspeaker, little more than 1/4 to 1 watt of
acoustic power is being generated. Even so, this little bit of
power is more than adequate to shake the windows and rouse
the neighbors .
The acoustic power generated by earlier models of commercial
jet aircraft far exceeds the output of the hi-fi or even the
80 or so watts produced by an energetic orchestra in concert.
These craft will generate as much as 40,000 watts at full take-
off throttle. It is possible for a person to briefly generate
as much as 1/10 watt and a trained singer can approach a full
1 watt acoustic output for a short time.
It is possible to convert acoustic power into a flow of heat
and this may be accumulated as heat energy. If this energy
can be contained so,that it can be accumulated over a
long period of time, the normal conversational talker
can heat up a cup of tea in 39 years or 100,000 football fans
could, conceivably, do it in 4 seconds. The point is that it
is possible to meas-ure noise in terms of the time integrated
(accumulated) measure of noise intensity. This will result
in a measure of total acoustic energy. The reasoning behind
this measurement is that people seem to react to the total
energy of noise environments rather than to only the power
generated by single events. Thus, it is desirable to define
fluctuating noise environments in terms of the constant noise
level which generates the same energy. This is done to obtain
an average level over a given period of time, nominally one
hour. The Hourly Noise Level (HNL) can thus be defined as the
City of Newptrrt Beach
Single Event Noise Exposure Level SENEL
The Single Event Noise Exposure Level is also dependent upon
time, but it is somewhat different in its application.
Essentially, it is designed to determine the total acoustic
energy associated with a single event such as would be
generated by the passage of a single vehicle or aircraft.
A flyby of a single aircraft will cause the acoustic level
to gradually rise, reach a peak and then fall. The total
area under a curve representing this flyby is proportional
to the SENEL. The SENEL differs from the other measures
discussed above in that they are averaged in time. That
is, the total energy is divided by the total number of seconds
required to make the record. The main difference between
these two records, then, is that an SENEL will always result
in a number that is higher than the peak level measured and
will represent a single event, while an HNL (or CNEL) will
always result in a number that is lower than the peak levels
measured and will represent the integrated energy -average
level for all of the events that occurred during the time
period specified by the measurement (one hour, one day, or one
year).
An approximation of SENEL may be obtained by the following
procedure:

SECTION 1 - HIGHWAY NOISE
Existing Highway Noise
Existing highway noise levels and contours were measured and calcu-
lated by Wyle Laboratories as a major p6rtion of their consultant
study: "Analysis of Highway Traffic Noise in Newport Beach,
California". Wyle Laboratories' major findings are included
herein in the form of a map entitled "Existing CNEL Contours",
several charts, and a general discussion of the existing highway
noise environment. (Please refer to the Wyle Laboratories
report for a more -detailed discussion of their methodology and
findings.)
COMMUNITY NOISE EQUIVALENT LEVEL CONTOURS
The Existing CNEL Contours map (Figure 4) illustrates the
penetration of highway noise into adjacent neighborhoods. Each
contour line represents the measured and calculated maximum
penetration of noise at each particular "Community Noise
Equivalent Level" (CNEL). As previously discussed, CNEL is a
time -integrated measure of noise, over a 24-hour period, with a
weighted Average which accounts for greater sensitivity to noise
in the evening hours. CNEL numbers indicate the relative noisiness
of various locations over a 24-hour period.
An examination of Figure 4 shows that CNEL values above 60 decibels
(dB) may be found at most locations within a block of any major
arterial street. CNEL values in the area of 60 dB will interfere
with some activities and may result in sporadic complaints. More
critical are those areas where the 65 or 70 dB CNEL contours extend
into residential neighborhoods, such as: 1) Coast Highway in the
City of Newport Beach
i
West Newport, Bayshores, and Corona del Mar areas; 2) Balboa
Boulevard on the Balboa Peninsula; 3) Dover Drive, and
4) Irvine Avenue.

HOURLY NOISE LEVELS
Another useful measure of highway noise is the "Hourly Noise
Level" (HNL) which represents the average noise level for a
one -hour period, as previously discussed in the "Quantification
of Noise" section of this Element. Figures 5 through
-� g g 13 illustrate
the Hourly Noise Levels (HNL) at various curbside locations within
the City during a single 24-hour period. Busy areas such as
Pacific Coast Highway at Dover Drive and Newport Boulevard
(Figures 5 and 6) show constant levels throughout the 24-hour
day with less than a 10 dB total variation. Figure 7, Pacific Coa
st
ast
Highway at Bayside Drive, shows some variation with traffic
-- decreases between 1:00 and 6:00 a.m., but even here there is
1 only 13 dB variation between the low and high points during the
day. Greater variation is seen at Jamboree and Ford Roads and
Irvine and Francisco (Figures 8 and 9). These locations become
quieter at night and only an occasional vehicle will pass by
during the early morning hours. Variations above 15 or 16 dB
are common on these streets. Figures 10 through 13, showing
calculated noise levels derived from traffic data, indicate similar
results. These latter figures contain noise levels calculated
from both summer and winter traffic. They graphically illustrate
the tendency for lower traffic levels and hence less
noise at
night in the winter. This is particularly obvious at Balboa
Boulevard and Pacific Coast. Highway, as reported in Figure 10.

' PROPAGATION OF TRAFFIC NOISE INTO THE COMMUNITY
All the levels reported in Figures 5 thr6ugh113 were measured
or calculated at curbside. According to Wy'le Laboratories, where
there are no barriers to the sound fields, such as store
,— fronts, walls, hills, or other solid partitions, the sound '
levels may be expected to attenuate by approximately 5 to 7
�-- dB in the first 50 feet of distance. The existence of barriers i rs
may reduce the nearby levels, by an additional 10 to 15 dB.
At distances beyond 200 feet, the effects of such barriers are
' small. However, the normal spreading losses at 200 feet will
generally reduce the traffic noise to less than 60 dB, thus,
-- normally removing any cause for concern.
�— COMPARISON OF NEWPORT BEACH NOISE LEVELS WITH OTHER AREAS
Figure 14 illustrates the HNL values -found in Newport Beach
�— as compared to other area
s as throughout the United States,
�— including rural farming communities and downtown locations in
Los Angeles and New York City. This chart indicates that the
'— noise levels near major arterials in Newport Beach are substantially
lower than those found in large cities. The noise levels in the
�..- Newport Beach residential neighborhoods are ave-rage, falling
within the range of those found in residential neighborhoods in
other parts of the country.

Projected Highway Noise
Future highway noise levels and contours were projected by
Wyle Laboratories, based on roadway capacities. These noise
levels and contours are illustrated on the map entitled "Projected
Future C.NEL Contours" (Figure 15). It is anticipated that
these noise levels and contours will be reached at approximately
the same time as the City of Newport Beach is "built -out" (all
vacant land being developed), which should occur by 1990.
The noise levels and contours shown in Figure 15 are based
on current and assumed typical highway configurations and
current automotive design. A change in these factors could
reduce noise levels at the source and reduce the propagation of
noise, thus pulling the contour lines in closer to the roadway.
An average propagation loss, as shown in Figure 16, has been
used to determine the actual placement of each contour line where
the roadway is level with the surrounding ground level (or
assumed to be). If a roadway is elevated, the high level contours
(70 and 65 dB curves) will shrink in. This is because the
edge of the road will shield some of the noise of the cars from
residences very close to the road. At greater distances (such as
the 60 decibel contour), this shielding is non-existent and the
raised roadway does not offer any reduction. In areas where a
roadway is depressed, there will be a 5 or 6 dB reduction, of all
levels. Short sections of depressed roadway do not offer much
advantage, but a long section would give this desirable effect.

In their report Veneklasen & Associates strongly recommended that
a CNEL value of 60dBA be used as a boundary defining the noise
impact area around Orange County Airport. Veneklasen based
this recommendation upon the results of studies which have
quantified certain aspects of noise which may have a bearing
on the psychological state of individuals or of a large population
exposed to high levels of aircraft noise.
The noise impact area as defined by Veneklasen (within the 60
dBA CNEL contour) includes several residential neighborhoods
designated for continued residential land use in the Residential
Growth Element, including portions of Santa Ana Heights, Dover
Shores, and the Bluffs.
A more recent study conducted by Veneklasen & Associates, "Aircraft
Noise Level Study", October 18, 1972, measured aircraft take -off
noise levels at ten residential sites in Newport Beach. This
study concluded that the measured noise levels found were
consistent with the earlier CNEL contours, and that speech inter-
ference and sleep disturbance are frequent occurences. The purpose
of this study was to provide support data for the larger report
illustrating the adverse effect of aircraft noise on property
values: "Studies Related to Jet Aircraft -Originated Noise Levels
and the Economic impact Upon Residential Property Values Associated
with Orange County Airport", February 12, 1974, Manhinney & Long,
and Veneklasen & Associates. This study concluded that the aircraft
noise has caused a relative decline in property values in excess
of 14% for those homes located under or near the flight path.

STATE REQUIREMENTS
The State of California has adopted the following noise criteria
for defining airport noise impact boundaries (Orange County Airport
falls into the "(b)" category):
It
Limitations on airport noise in residential
communities are hereby established.
(a) The criterion community noise equivalent
level (CNEL) is 65 dB for proposed new airports
and for vacated military airports being
converted to civilian use.
(b) Giving due consideration to economic and
technological feasibility, the criterion
community noise equivalent level (CNEL) for
existing civilian airports (except as follows)
is 70 dB until December 31, 1985, and 65
dB thereafter.
(c) The criterion CNEL for airports which have
4-engine turbojet or turbofan air carrier air-
craft operations and at least 25,000 annual
air carrier operations (takeoffs plus landings)
is as follows:
Date CNEL in decibels
Effective date of regulations to 12-31-75----80
1-1 76 to 12-31-80--------------------------- 75
1-1-81 to 12-31-85--------------------------- 70

SECTION 2 - AIRCRAFT NOISE
Since the appearance of turbojet and turbofan propulsion systems
in the field of commercial aviation, a significant noise
intrusion has invaded many homes located near flight paths
within the City of Newport Beach. In addition, military heli-
copters from the nearby marine airfield and police helicopters
contribute to the overall noise levels in some parts of the
City.
It is not the intent of this section of the Noise Element to
attempt a comprehensive survey of aircraft noise conditions which
are covered in depth in many other studies, but to indicate the
noise impact areas and general effects of aircraft noise as
identified by others.
Commercial Jets
In 1970, the City of Newport Beach contracted with the consulting
firms of Wilsey &•Ham, Planners, Paul S. Veneklasen & Associates,
Acoustical Engineers, and Darley/Lobar Associates, Economists,
to study the impact of Orange County Airport on the City of
Newport Beach. This study culminated in the report: "Orange
County Airport Impact Study", January, 1972.
As part of this study, Paul S. Veneklasen & Associates conducted a
noise measurement survey and then constructed noise level contours.
These contours are shown in Figure 17. The contours shown
are based on level of operations which were determined by
observation during the noise measurement survey and on the,
then, current 1972 airline schedules. In order to illustrate the
benefits from noise abatement takeoffs, Veneklasen drew contours
City of Nev-)ort Beach
Section 5005 of the California Administrative Code lists the
1�
findings of the state in adopting these airport noise standards:
_ "Citizens residing in the vicinity of airports
are exposed to the noise of aircraft operations.
There have been numerous instances wherein
individual citizens or organized citizen
groups have complained about airport noise to
various authorities. The severity of these
complaints has ranged from a few telephone
calls to organized legal action. Many of
these cases have been studied by acoustics
research workers under sponsorship of governmental
_ and private organizations. These studies have
generally shown that the severity of the complaint
is principally associated with a combination of
the following factors:
(a) Magnitude and duration of the noise from
aircraft operations;
�--
b
( ) Number of aircraft operations; and
(c) Time of occurrence during the day (daytime,
evening or night).
There are many reasons given by residents for
their complaints; however, those most often
cited are interference with speech communication,
TV and sleep. A number of studies have been
made related to speech interference and hearing
damage, and some studies have been made related
to sleep disturbance and other physiological
effects. These studies provide substantial
evidence for the relationship between noise
level and its interference with speech communi-
cation and its effect relative to hearing
Y loss. Significantly less information is
available from the results of sleep and physiological
studies.
r_ In order to provide a systematic method for
evaluating and eventually reducing noise
incompatibilities in the vicinity of airports,
it is necessary to quantify the noise problem.
For this purpose, these regulations establish a
procedure for defining a noise impact area sur-
rounding an individual airport. The criteria
and noise levels utilized to define the boundaries
of the noise impact area have been based on
existing evidence from studies of community
noise reaction, noise interference with speech
and sleep, and noise induced hearing loss.,,
_ The purpose of the state regulations and a methodology for
controlling and.reducin o.se problems r iso listed within
Cit OUL or eaci
�- v
p
the California Administrative Code.
"The purpose of these regulations is to provide
a positive basis to accomplish resolution of
-- existing noise problems in communities surrounding
airports and to prevent the development of new
noise problems. To accomplish this purpose,
these regulations establish a quantitative
framework within which the various interested
parties (i.e., airport proprietors, aircraft
operators, local communities, counties and the
'- state) can work together effectively to reduce
and prevent airport noise problems.
The methods whereby the impact of airport noise ~
shall be controlled and reduced include but
are not limited to the following:
(a) Encouraging use of the airport by aircraft
classes with lower noise level characteristics
and discouraging use by higher noise level
aircraft classes;
(b) Encouraging approach and departure flight
paths and procedures to minimize the noise in
residential areas;
(c) Planning runway utilization schedules to
take into account adjacent residential areas,
noise characteristics of aircraft and noise
sensitive time periods;
(d) Reduction of the flight frequency, par-
ticularly in the most noise sensitive time
_ periods and by the noisier aircraft;
(e) Employing shielding for advantage, using
natural terrain, buildings, et cetera; and
(f) Development of a compatible land use within
the noise impact boundary.
Preference shall be given to actions which reduce
the impact of airport noise on existing communities.
Land use conversion involving existing residential
communities shall normally be considered the
least desirable action for achieving compliance
with these regulations."
Section 5062 of the California Administrative Code probides that:
"No airport proprietor shall operate his airport with a noise impact
area of other than zero unless said operator has a variance as
— prescribed in Article 11 of this subchapter of these regulations".
City of New -port Beac
Orange County Airport does currently have a noise impact area of
greater than zero (since the 70 dB CNEL contour includes residential
neighborhoods) and has submitted an application for variance, as
contained in the "Report to the State of California Director of
Aeronautics on the Compliance of Orange County Airport with the
Adopted Noise Regulations for California Airports", January 26, 1974.
This variance request is currently under consideration by the
California Department of Aeronautics.
�, � City of Newport Beach
EXISTING CITY POLICY ON ORANGE COUNTY AIRPORT
The current City of Newport Beach policy regarding Orange County
Airport was adopted by the City Council on February 14, 1972 and
states:
"In developing its position regarding issues
related to Orange County Airport, the Newport
Beach City Council has always carefully examined
pertinent aviation technical studies; has weighed
the desires of citizens of the County for commercial
air transportation; the assumed benefits in employment
- and trade from business and industry attracted
to the airport and adjacent airport industrial
development; the continuing commitment of the
County of Orange to preserve viable general aviation
facilities; and finally, the responsibility of
public officials to protect and enhance the comfort,
well-being and quality of residential living for
the citizens they serve.
After considering these factors, the Newport Beach
- City Council has concluded that it is in the
best interest of the City and an important
responsibility to assure its citizens, and the
tens of thousands of patrons of its water -oriented
recreation attractions, a continuation and enhance-
ment of the residential and outdoor recreational
environment. Therefore, it is essential that
-- effective measures be employed so that the noise
and pollution emanating from jet aircraft operations
at Orange County Airport can be constrained and
abated. To accomplish such objectives, the City
of Newport Beach offers the following findings and
recommendations for operation of Orange County
Airport.
Control of Commercial Jet Departures__
The control of commercial jet departures through
terminal lease restrictions appears to be the
most productive technique for immediate management
by local authorities of the noise problem.
The following conditions should govern the con-
tinuance of terminal access privileges by com-
mercial carriers at Orange County Airport:
(a) The hours of operation should be from
7:00 a.m. to 10:00 p.m. only. I
(b) The type of jet aircraft should be limited
to those no louder than the Boeing 737 or Douglas
"
DC-9 and with a gross weight not to exceed
95,000 p u Sef Nuvypprt Beach
1
EXISTING CITY POLICY (Continued)
(c) The permitted number of daily operations
should be restricted to a number not to exceed
the average daily level for the twelve months
immediately preceding expiration of the present
1 e a s es .
(d) Noise abatement flight procedures should be
vigorously enforced by airport management. To
aid in this effort and to provide a reliable and
scientific basis for assessing the noise problem,
_ suitable measurement equipment and competent
operators should continue to be maintained at
ithe airport.
*'"-- (e) No terminal access privileges should be
granted to any new carrier who proposes to use
W jet aircraft, or who may receive authority to
serve any point where the ultimate destination
is more than 400 miles from Orange County. No
expanded terminal facilities should be permitted,
nor should any commercial carrier be allowed to
construct terminal facilities which would be
independent of the County's regulatory controls.
(f) No commercial carrier should be permitted to
use aircraft not equipped with the latest smoke
reduction retrofit equipment.
General Aviation Operations
Piston -driven private and commercial aircraft do
not appear to constitute a serious environmental
pollution problem. However, the uncontrolled
operation of privately owned jet powered aircraft
poses an increasingly serious noise problem.
The County should maintain strict measures to
limit times of operation, flight procedures and
,V noise abatement patterns for such aircraft. If
the Director of Aviation cannot attest to a
significant improvement in this problem within a
reasonable period of time, the use of such jet
powered aircraft should be banned from the airport.
New Facilities
The Orange County Board of Supervisors has elected
to be the local agency providigg commercial airline
facilities for this metropolitan area. The Board
should acknowledge that the Orange County Airport
is not, and in all probability will never be, an
acceptable facility for jet powered aircraft. Further
_ numerous technical studies have demonstrated that
the only sensible solution to the county's aviation
facilities needs is the development of an alternate
jet capable airport. The City Council urges the
Board of Supervisors and all aviation authorities
to make .a str&cg tment to t i s jectiv
wit ew orb �uacb
1
UEXISTING CITY POLICY (Continued)
Until such time as such a facility is available
for use, strong measures must be employed to
control the environmental problems created by
Orange County Airport."
The City of Newport Beach has filed a complaint, on May 16, 1974,
tagainst the County of Orange which seeks to abate the public nuisance
caused by aircraft noise. This lawsuit asks that the court order the
county to provide assurances that effective noise abatement actions
twill be taken. It is hoped that this lawsuit will provide the
vehicle by which the City df Newport Beach and the County of Orange
can agree; by way of a written, binding document; to the elements
twhich are necessary to provide said effective aircraft noise
abatement.

HELICOPTERS
Helicopters, both police and military, are another significant source
of aircraft noise within Newport Beach. This subsection on heli-
copter noise is based on the helicopter noise section of the Wyle
Laboratories Study: "Analyst's of Highway Traffic Noise in Newport
Beach, California".
POLICE HELICOPTERS
The City of Newport Beach operates two police helicopters for
surveillance of areas sensitive to crime. These craft have no set
pattern of operation and might be found at any point at -any time.
During emergency situations when the helicopter is moving to a
scene of action, noise generation is quite high, but duration
and frequency (as received by a given resident under the flight
path) are very low.
Figure 18, below, lists the three different operating altitudes
together with a progression to CNEL figures under some different
assumed flight patterns.

City of Newport o�au,
Figure 18 indicates that the police helicopter, though quite noticea-
ble during the time when it is flying over, generates relatively low
total acoustic energy averages over a day.
Helicopter overflights are very singular, relatively nonrepetitive
events. The foregoing data therefore tends to confirm a conclusion
that can be drawn from everyday experience, that during the day such
events will not usually cause extended annoyance and complaints.
At night, however, repetition throughout the night is not a necessary
condition for annoyance. A single event which produces complete
awakening or even adequate recall can produce severe annoyance.
Continuous night -after -night repetition will lead to inevitable
complaint and in some cases only a few repetitions will arouse
vigorous action.
MILITARY HELICOPTERS
Military helicopters flying over the City of Newport Beach are usually
from the Marine Corps Air Station (MCAS) in Santa Ana in support
of operations at Camp Pendleton. The FAA has assigned a total of
eight routes for their use over populated areas. These routes are
used when visual flight is possible.
The military helicopters are permitted to fly under any weather
conditions wherein the pilots can maintain ground contact. The
normal minimum altitude requirements are 600 feet above sea level
for inbound, and 800 feet for outbound craft. All aircraft are
required to fly 500 feet below cloud banks under special Visual
Flight Rule conditions, but the military helicopters are permitted
the additional allowance of being able to fly if they can maintain
ground contact. Under clear skies, these craft fly at about 1800
City of Newport Beach
feet above sea level, leaving considerably more clearance with less
noise.
The one route for military helicopters that affects the City of
Newport Beach is called the "Palisades Route". This route is
used to fly from MCAS to the sea, and may be described as
running due south from the Big Canyon Reservoir and 30 degrees east
from that reservoir. The assigned path is 1/4 mile wide. Figure 19
indicates this flight path and the60 and 55 dB(A) CNEL contours.
Populated areas within the city limits, directly under the flight
path, include sections of Corona del Mar and the Harbor View Hills
areas.
A flight path 600 feet above sea level is only 300 feet above the
Big Canyon Reservoir. The developments being constructed around
Spyglass Hill are even higher and could, conceivably, be within
120 feet of a helicopter if a craft used the eastern -most edge
of the path.
The whole of Surrey Drive in the Cameo -Highlands is approximately
400 feet below this flight path minimum altitude.
The helicopter CNEL contours were developed by Wyle laboratories
based on an average sound level generation of four types of military
helicopters operating in this flight path and an assumed altitude of
1,000 feet.
Maximum sound pressure levels that may be expected along this 60 dB
CNEL contour will approximate 83 dBA. Flyovers of military heli-
copters may cause some annoyance, possibly leading to complaints,
where residences are less than 2400 feet from the flight path
t
City of Nt:;wport Beach
within the 60 dB(A) CNEL contour. At greater distances, the
annoyance will decrease to levels below those of traffic noise.
The Harbor View Elementary School and the Intermediate School
on San Joaquin bills Road are the most potentially sensitive
recipients of military helicopter noise.

SECTION 3 - STATIONARY SOURCES
Existing Conditions
This category of noise impacts includes such sources as:
1.
Industrial Operations
--
2.
Air Conditioning and Swimming Pool Motors
3.
Maintenance and Construction Operations
'
While no research
studies have been conducted on stationary noise
sources in
Newport Beach, it is apparent that this category of
noise has a
relatively minor impact. Few complaints of continuing
noise from
stationary sources have been received.
Most of the
industry in the City of Newport Beach could be classified
as "light"
industry involving mostly research and development
activities;
no major "heavy" industries (with large noise -producing
machinery)
are located in the City.
In view of the large amount of building activity in the City,
periodic noise impacts from operation of construction equipment
tmust be expected. However, these noise impacts are temporary in
tnature and generally occur only in the daytime.
tFuture Conditions
It is anticipated that noise from stationary sources will not become
ta major problem in the future. All of the developing industrial
areas are of the "industrial park" type, consisting of "light"
tindustrial operations. As the City becomes more fully developed,
noise from construction activity should taper off.

SECTION 4 - NOISE CONTROL. PROGRAM
In order to protect the citizens of the City from the adverse effects
of an uncontrolled noise environment, the City of Newport Beach will
undertake a "noise control program", including the control of
noise at its source, and the attenuation of noise between the
source and the receiver. The City will:
1. Extend the California Administrative Code
requirements for noise mitigation in the
design and construction of new multi -family
residential developments (Article 4 of the CAC)
to include all types of residential development.
(It is recognized that revisions to the CAC
requirements will be necessary to assure
reasonability and practicability in their
application to single-family residential development.)
2. Exert all possible influence on the design of
the Corona del Mar freeway to assure that it
will be constructed as a "depressed" roadway and
that all other practical noise mitigation measures
will be implemented.
3. Consider the adopt4on of a local noise control
ordinance.
4. Continue to require that noise impact analysis be
included in Environmental Impact Reports, including
the noise impact of the proposed development on other
properties, and the effect of existing or projected
noise levels on the future users or residents of the
', � City of Nevaport Beach
I t ,
proposed development.
5. Continue to enforce the California Vehicle Code
Provisions relating to modified muffler systems.
6. Consider noise impacts when purchasing City vehicles
and other City -owned equipment.
7. Continue to vigorously oppose the expansion
of Orange County Airport and work towards imple-
mentation of the City's airport policy, as
stated in Section 2 of this Element. In
addition the City will:
A. Encourage the reinstatement of the
"Preferential Runway Program". This
program, which involved scheduling
takeoffs in a northerly direction
during morning hours when wind condi-
tions were favorable, had a definite bene-
ficial effect in reducing jet aircraft
noise over the City of Newport Beach.
The program was terminated by the
Board of Supervisors contrary to the
advice of the airport noise abatement
staff.
S. Encourage the County Board of Supervisors
to initiate a program of economic incentives
for airlines to reduce the levels of noise
generated by their aircraft.
C. Support the implementation of programs for
reduction of noise emissions from aircraft,
as retrofit devices.
City of Newpurt Beach
Support the development and enforcement of more
stringent State and Federal vehicle and Aircraft

SUBJ: Amendment to Wyle Laboratories Noise Study Contract
In reviewing the draft of the Noise Study Report prepared by
Wyle Laboratories, it was discovered that the section on
projected highway noise levels was not based on the best current
information. During the time the study was in preparation, the
only information available consisted of proposed highway
capacities based on service level "D". Since then, the
Circulation Element has been adopted and better projection of
traffic volumes has been completed.
In order to complete the Wyle Laboratories Report (which will
be the major input to the Noise Element), the highway noise
level projections must be recalculated, based on the new traffic
volume projections. These noise level projections also become
critical in view of a recently -adopted section of the California
Administrative Code which requires special sound insulation
design and construction for residential structures located
gear major noise sources (highways and aircraft flight patterns);
the determination of where sound insulation is required is to be
based on the noise level contours contained in local General
Plan Noise Elements. (This subject will be discussed in detail
with the Noise Element).
Staff would suggest that, since the discrepancy in the Wyle
Report is due to the traffic data supplied by the City,based
on information that was available at the time, an amendment to
the contract with Wyle Laboratories be authorized for the
recalculation of projected noise level contours along major
highways. Wyle Laboratories has indicated that the cost of such
services will be $2,145.00.
Funding
Since the original noise study was initiated in FY 1972-73,
there is no fund in the current budget for Noise Element studies,
per se. However, a "Noise Ordinance Studies" fund is included,
for which the sum of $1,5.00.,.00 has been authorized. Staff
would suggest that the Noise Ordinance Studies fund be increased
City of Newport Beach
AW,
TO: • City Council - 2
to $2,145.00 by transferring $645.00 to this fund from the
"Community Design Studies" fund (for which $10,000.00 is
currently authorized) and that the utilization of this fund
for the additional Noise Study work by Wyle Laboratories be
authorized. (Per, Budget Amendment BA- ) .
Recommended Action
If desired:
1. Adopt the attached Resolution, authorizing execution
of an amendment to the Wyle Laboratories Contract.

MEMORANDUM
TO: Rod Gunn
FROM: Al Krier
SUBJECT: Roadway Capacity Map
DATE: October 25, 1973
JOB: 256.000
Enclosed is the "Composite Road Network" reap with the capacities (in 1, 0001s)
plotted in red for those roads within the study area boundaries. Please note
that:
1) Two secondary roadways, Campus Drive around the Airport and the
second crossing of Upper Bay, have a capacity of 22, 000 rather than
14, 000. This is because some or all of the on -street parking is pro-
hibited, allowing the roadways to operate similar to four --lane divided
roadways.
2) Coast Highway between Newport Boulevard and Dover Drive is shown
with a capacity of 36, 000. This is a modified primary road with five
lanes on the westerly end, restricted access on the easterly end, and
part-time parking prohibitions.
3) Coast Highway in Corona del Mar is shown with a capacity of 32, 000>
as a result of part-time parking prohibitions.
The capacities shown are based on approximate service level "D". 1n
general this means that the roadways are capable of handling more traffic,
but only with considerable adverse affects.

PROPOSAL FOR HELICOPTER NOISE STUDY FOR THE
CITY OF NEWPORT BEACH
Wyle laboratories proposes to perform an additional study for the City of Newport Beach
which will involve the following tasks:
], Study of the flight operations of police and military helicopters operating within
the city limits to determine the type of equipment utilized and the details of the
operational procedures. This task assumes operational data will be made available
by the appropriate city and military agencies.
2. Measurement of helicopter noise under controlled conditions. A series of noise
measurements will be made of typical equipment utilized by the'police and
military to determine the noise characteristics. The controlled conditions include
takeoff, hover, flight and landing,. Measurements will be made• at three typical
locations for the police helicopters and three locations for the military helicopters.
Wyle assumes assistance will be given by, the necessary appropriate city or military
personnel in this measurement program.
$. A letter report on the noise generated by helicopter operations in the City of Newport
Beach will be prepared based on the data obtained in Tasks t and 2. This report l
will include:
a. A map showing the routes followed by military helicopters and some
-----I typical routes followed by police helicopters.
b. Projected CNEL contours for military helicopters in South Newport Beach.
C, Typical A -weighted sound pressure levels associated with both military and
police operations.
d. Recommendation as to possible alternate operational procedures which could
be followed by helicopters in order to reduce the noise impact.
e. Suggested procedures for zoning and building construction to make the land
impacted by noise compatible for its intended use.

7VWVy1ceoratoriesproposes to perform an additional study for the City of Newport Beach
l involve the following tasks:
Study of the flight operations of police and military helicopters operating within
I the city limits to determine the type of equipment utilized and the details of the
operational procedures. This task assumes operational data will be made available
! by the appropriate city and military agencies,
2, Measurement of helicopter noise under controlled conditions. A series of noise
measurements will be made of typical equipment utilized by the police and
military to determine the noise characteristics. The controlled conditions include
takeoff, hover, flight and landing. Measurements will be made at three typical
locations for the police helicopters and three locations for the military helicopters:
Wyle assumes assistance will be given by the necessary appropriate city or military
personnel in this measurement program.
3. A letter report on the noise generated by helicopter operations in the City of Newport
Beach will be prepared based on the data obtained in Tasks I and 2. This report
will include:
CIO A map showing the routes followed by military helicopters and some
typical routes followed by police helicopters.
b. Projected CNEL contours for military helicopters in South Newport Beach.
c, Typical A -weighted sound pressure levels associated with both military and
police operations.
0
d, Recommendation as to possible alternate operational procedures which could
be followed by helicopters in order to reduce the noise impact.
e, Suggested procedures for zoning and building construction to make the land
impacted by noise compatible for its intended use.
City of Newport Beach
Helicopter Noise Survey
It is suggested that the Heliport be used for measurements of the police 1�Q�Ga
helicopters. If Newport Beach can induce the milibary helicopters to
fly a specific pattern over the city this should also be done at the
heliport for safty reasons. It is i expected, however, that it will only
be possible to obtain information about where and when a milibary helicoptso
will be over and measurements must be maazx made as best we can.
DATA: This will be taken at a slant distance of 500 feet. Altitude
and distance may be adjusted to keep the microphone free of prop blast.
It is suggested that this be accomplished with a distance of 353 feet and
an altitude of 353 feet, making a slant angle of 450 above horikzontal.
HOVER: The acoustic output of the helicopter will vary from time
to time. with changes in wind velocity and direction and it
is suggested that measurements be made for a full 5 minutes
while the craft is held as motionless in the air as possible.
TAKEOFF AND LANDING: Again a statistical average is needed. A minimum
of 5 takeoffs and landings xiii are desired. Microphone is to
be placed at a distance of 353 feet from ground zero and the
craft should rise to a height of 353 feet.
FLYBY: The helicopter should Mass over a given pim point 5 times running
in one direction in a line perpendicular to the line tninkin
joining the point to the microphone. Then the microphone should
be moved 900 around the ground zero paint.andxtkaxfiyhysxpRxioxm$iI
agaznx The measurements should be repeated at this posibion to
reduce the ei'fects of local protuberances. The 10 flyby
data points will then be averaged.
CitYFcrF>N1P-A➢, rt Beach
the follow,@
The city of Newport Beach will sbtais supply/operational data xjmx concerning
the police and military hel&copters.so that it may be incorporated into maps
defining the levels expected over the city from each of these #mw two sources
of noise;
1..Routes traveled by the aircraft
2. Time schedules used ty the aircraft
3. Altitudes
4. Speed
5. Models numbers of each aircraft type to be spa studied.
It is expected that some of the above information will not be available, but
computation of the average levels expected over the city at si any given point
aaax will required as much of this information as possible.
it
For the military aircraft, slant distances of routine overflights will be
determined optically if it is not possible to make controlled flight measurements
of this craft. The ImEntionsxfox location for measurement of the military
sa#as aircraft will be determined in conference with Newport Beach personnel.
Data taken s during this dxskmdyxhx*kn brief study will be compared with
published data taken with on other helicopters to correct local. anom9lies.

FROM: Carl M. Neuhausen, Advance Planning Administrator
SUBJECT: Proposed Studies for Noise Element of the General Plan
Model Noise Element
At the last regular meeting of the City Council on August 21,
1972, several questions were raised regarding the various noise
studies of the General Plan. The staff was asked to investigate
the possibility of utilizT.ng the model noise element being de-
veloped by the City of Inglewood as a means of saving any of
the ?roposed costs or study efforts required to complete the
City s Noise Element.
I have learned through conversations with Mr. Randy Herlbert of
the Environmental Planning Division, City of Inglewood, that
their division is working on two separate noise elements: one -
their own city noise element, and second - the model noise ele-
ment being developed for the SCAG study committee. They are at
least four months away from completing the city noise element
and over six to eight months away from completing the model
noise element for SCAG. To utilize either of these elements
would mean a delay in our own study efforts which have now been
programmed for completion within the next five to six months.
The majority of work under our own program actually centers
around the development and mapping of various noise contours
from field measurements taken along the City's highway network
and at various other points throughout the Newport Beach commun-
ity. This embodies the major work efforts of the Consultant
and accordingly, accounts for over three -fourths of the costs
of the noise studies leading to the final noise element. Such
costs would be incurred regardless of the opportunity to utilize
any of the guidelines set forth in a model noise element.
Study of Helicopter Noise
Other questions raised by Council concerned the scope of the
noise studies, and particularly the study of noise as generated
by helicopter flights over the City. In following the State
requirements for local noise elements, we have 'not to date in-
cluded the study of helicopter noise within the program. I have
asked each consultant to consider adding these studies to their
scope of work and to report back on any additional costs which
City of Newport Beach
may be incurred. I would hope that such additional studies
could be added by separate contractor a future expansion
of any existing contracts we would have underway. With less
than a week's time to the next Council meeting, I will attempt
to gain an answer regarding the study of helicopter noise from
our consultants.

Consulting Services for Noise Element of the
P1 an
Since the introduction of a mandatory Noise Element under State
planning law, the Staff has investigated several alternative means
for including the new element as part of the City's General Plan.
The Noise Element essentially requires local cities to quantita-
tively measure, analyze, and control various noise levels associated
with existing and future transportation facilities, including high-
ways, freeways, mass transit systems, and ground air facilities.
(See attached Senate Bill 691.)
Due to the additional time, equipment, and technical expertise
needed to complete the noise studies, the Staff had solicited pro-
posals from various consultant firms for assistance in developing
the Noise Element of the Plan. On May 22, 1972, the Council author-
ized a joint consultant study between the firms Mawhinney & Long
and Paul S. Veneklasen & Associates to undertake the first portion
of studies related to aircraft noise and the Orange County Airport.
These studies are now underway and scheduled for completion by
November 1, 1972.
In reference to Senate Bill 691, further studies are also required,
specifically in regards to noise associated with highways, freeways
and mass transit systems. Two consultant firms have submitted
additional study proposals to the City; these being Paul S. Venek-
lasen and Associates, Santa Monica, and Wyle Laboratories, El
Segundo. We had asked that each proposal be designed around a
three-phase work program which coincides with other studies and
programs now underway as part of the General Plan. These three
phases include:
Phase I The measurement and analysis of noise
levels associated with existing transpor-
tation facilities.
Phase II The projection and analysis of future
noise levels associated with proposed
transportation facilities.
City uf Nvvvvort Beach
TO: City Council - 2.
Phase III The development of a comprehensive and
quantitative noise ordinance to control
existing and future noise levels.
The costs for developing all three phases of the study as out-
lined in the consultant proposals have varied from $13,600 to
$21,500. The monies allocated under the fiscal year 1972-1973
budget for such studies total $20,000.
After detailed review of each proposal, the Staff wishes to
recommend the appointment of Wyle Laboratories to undertake such
studies leading to a Noise Element of the General Plan and a
comprehensive City-wide noise ordinance. Through extensive
experience in the acoustical research field and their past and
pres-ent work in similar projects, the firm is fully qualified to
carry out the study.
The Staff would further recommend that the City Council authorize
the Mayor and City Clerk to execute an agreement between the City
of Newport Beach and Wyle Laboratories to perform such services
in an amount not to exceed $13,600.

REVISED APPROACH - STUDIES RELATING TO THE NOISE ELEMENT
OF THE CITY OF NEWPORT BEACH GENERAL PLAN
Subsequent to the submission of Wyle's proposal on May 5, 1972, discussions were held
with the representative of Newport Beach which resulted in a modification of the level
of effort originally proposed by Wyle. As a result of these modifications, we are pro-
posing to perform all three phases under the terms defined in the cover letter. The
revised program is defined in the following paragraphs. Unless otherwise specified, the
operational details of the program will be in accordance with our previous proposal.
Phase I - Noise StudX of Traffic on Existing Highways -• To Be Accomplished Between
September 1, 1972 and November 15, 1972
This.phase will involve three tasks. The first task will be to determine and map noise
contours according to the guidelines contained in Senate Bill 691 for the following
major highways in the City of Newport Beach. These highways are indicated by the
heavy lines on Figure 1. The second task will be'to determine ambient noise levels
in the community for various types of land uses. The final task will be to make
recommendations on how to minimize the noise impact of highways on various land
uses within the City of Newport Beach.
Wyle's approach to Phase I will be in accolydance with the Program Plan set forth in
our proposal of May 5, with the following exceptions:
Wyle will make the necessary field measurements and analytical studies to
develop actual highway noise levels in Newport Bench, however the noise
contours will be based on hourly highway traffic flow data supplied by the client.
o There will be a reduction in the number of highway sites (ref - page 5 of pro-
posal) to approximately 15; we believe this will be sufficient for developing
noise contours for the highway configuration depicted in Figure 1.
0 A data base sufficient for estimating noise contours in accordance with Senate
Bill 691 and projecting noise levels associated with the projected highway
system for Phase II.
The data developed in Phase I will be summarized in a matrix type format comparing
land use, highway type, vehicle type, traffic conditions, terrain characteristics, and
City of Newport Beach
other factors necessary for predicting noise levels associated with the, highway system
of Newport Beach.
Phase Ii - Noise Study of Projected Traffic on Existing and Proposed Highways -
Complete January 1, 1973
This phase will be to "determine and map the noise contours for projected levels of
traffic on all existing (per Figure 1 ) and proposed highways and freeways. Con-
clusions regarding appropriate site or route selection alternatives or noise ,impact
upon land uses shall be made for inclusion into the General Plan. "
I
The Phase II study will be in relation to'transportation studies currently in process
fqr:
(�) Newport Freeway j
f ; �
(2) Corono Del Mar Freeway
(3) San Joaquin Hills Road
(4) Dover Drive F
(5) Bayside Drive '
Wyle will use the traffic noise matrix developed in Phase I, plus additional published
information to develop noise contours associated with projected transportation systems.
♦ 4
Phase III Development of City Ordinance - Complete March 1, 1973
As a final phase, a noise ordinance will be developed for ultimate adoption as part of
the Mqnicipal Code. This ordinance would reflect relevant elements of other city noise
ordinances - such as the California league of Quiet Cities Model Noise Ordinance. It
would also reflect the results of the investigation of Phase I and Phase II.
Wyle will act in advisory capacity to the City of Newport Beach in this phase of the
program. In this capacity, we will perform the following tasks:
• Submit an outline of our recommendations relevant to current and projected noise
levels which we believe should be included in the Ordinance.
• Advise, as required, in the preparation of the draft Ordinance.
o Review and comment on the draft version of the�Ordinance which will be prepared
by the City of Newport Beach.

REVISED APPROACH —STUDIES RELATING TO THE NOISE ELEMENT
OF THE CITY OF NEWPORT BEACH GENERAL PLAN
r
Subsequent to the submission of Wyle's proposal on May 5, 1972, discussions were held
with the representative of Newport Beach which resulted in a modification of the level
of effort originally proposed by Wyle. As a result of these modifications, we are pro-
posing to perform all three phases under the terms defined in the cover -letter. The
revised program is defined in the following paragraphs. Unless otherwise specified, the
operational details of the program will be in accordance with our previous proposal.
Phase I — Noise Study of Traffic on Existing H
September 1, 1972 and November 1, 1972
es —To Be Accomplished Between
This phase will involve three tasks. The first flask will be to determine and map noise
contours according to the guidelines contained in Senate Bi11.6I1 for the following major
highways in the City of Newport Beach. These highways are indicated by the heavy lines
on Figure 1. The second task will be to determine ambient noise levels in the community
for various types of land uses. .The final task will be to make recommendations on how to
minimize the noise impact of highways on various land uses within the City of Newport
Beach.
Wyle's approach to Phase 1 will be in accordance with the Program Plan set forth in our
proposal of May 5, with the following exceptions:
• 'All calculations of noise levels due to highway traffic will be based on hourly traffic
estimate to be supplied by the City of Newport Beach.
e There will be a reduction in the number of highway and community measurement
sites to a level sufficient for developing noise contours for the highway configuration
' depicted in Figure 1.
• A data base sufficient for estimating noise contours in accordance with Senate Bill
691 and projecting noise levels associated with the projected highway system for
Phase 11.
City of Newport Beach
L 4
The data developed in Phase I will be summarized in a matrix type format comparing
land use, highway type, vehicle type, traffic conditions, terrain characteristics, and
other factors necessary for predicting noise levels associated with the highway system of
Newport Beach.
Phase II — Noise Study of Projected Traffic on Existing and Proposed Highways --- To Be
ccomp is ed Between January i, 1973 and Marc 1, 1973
This phase will be to "determine and map the noise contours for projected levels of traffic
r
on all existing and proposed highways and freeways. Conclusions regarding_ appropriate
site or route selection alternatives or noise impact upon land uses shall be made for
inclusion into the General Plan. "
The Phase II study will be in relation to the highway pattern depicted in heavy dashed
lines on Figure 1. Wyle will use the traffic noise matrix developed in Phase I, plus
additional published information to develop noise contours associated with projected
transportation systems.
Phase III — Development of City Ordinance — (Exact Schedule not Specified)
As a final phase, a noise ordinance will be developed for ultimate adoption as a part of
the Municipal Code. This ordinance would reflect relevant elements.of other city noise
ordinances - such as the California league of Quiet Cities Model Noise Ordinance. It'
would also reflect the results of the investigation of Phase I and phase II.
Wyle will act in an advisory capacity to the City of Newport Beach in this phase of the
program. In this capacity, we will perform the following tasks:
• Submit an outline of our recommendations relevant to current and projected noise
levels which we believe should be included in the Ordinance.
• Advise, as required, in the preparation of the draft Ordinance.
•
Review and comment on the draft version of the Ordinance which will be prepared
by the City of Newport Beach.

SUBJECT: Status of the Noise Element
Since the introduction of a mandatory Noise Element under State
planning law, the Staff has investigated several alternative means
for including the new -element as part of the City' s General Plan.
The Noise Element essentially requires local cities to quantita-
tively measure, analyze and control various noise levels associ-
ated with existing and future transportation facilities, includ-
ing highways, freeways, mass transit systems, and ground/air
facilities. (See attached bill.)
Due to the additional time, equipment and technical expertise
needed to complete the noise studies, I have excluded the first
possible alternative of utilizing the present City Staff. In
reviewing the'various consultant firms which are now under con-
tract to assist in developing the General Plan, the present
scope of their work and/or th•e background capabilities of each
firm would also preclude them from successfully completing a
Noise Clement,
The Staff is now completing investigations'into the probable
means and costs of utilizing an additional outside consultant
to develop the Noise Element of th•e Plan. Two leadi6g''acous,-
tical consultants have been requested to submit proposals to the
City, including: Paul S. Veneklasen and Associates, Santa Monica,
and Wyle Laboratories, E1 Segundo. We have asked that each pro-
posal be designed around a three-phase work program which coin-
cides with other studies and programs now underway as.part of
the General Plan. The three phases will include:
Phase I The measurement and analysis of noise levels
associated with existing transportation
facilities.
Phase 11 The projection and analysis of future noise
levels associated with proposed transporta-
tion facilities.
Phase III The development of a comprehensive and,
quantitative noise ordinance to control
existing and future noise levels.
In view of the -existing noise studies related to air transporta-
tion facilities, both consultants were asked to limit their.
proposals to the study of vehicular traffic and mass transit?

systems as outlined under the State law. It appears that
` sufficient data would be made available from the Parsons
report and Wilsey -Nam study on noise levels to satisfy the
States crit,gria. For any further studies related to air
traffic, the estimated time and costs outlined in each pro-
posal would have to be increased accordingly.
The Staff has received a preliminary proposal from Paul S.
Yeneklasen and Associates which estimates the following costs
for the three phases of the noise study program:
Phase I Existing Noise Level Analysis $13$00
Phase II Projected Noise Level Analysis 2,500
Phase III Development of noise Ordinance 3,000
Total Program Cost $199,000
The second proposal from Wyle Laboratories is being completed
by the firm and will be submitted to the City by the end of
April.
During t!he present fiscal year, 1971-72, the City Council had
appropriated $104,000 for various consultant studies in -con-
nection with the General Plan Program. The amount of $79,000
has now been encumbered either by contract or payment,ty;the
fol.l owing consultants:
Transportation Consultant $39,000 }
Economic Consultant' 25,000 }
Mousing Consultant 10,000
Geologic Consultant 51000
The remaining $25,000 has generally been earmarked for matching
funds which would be used i-n developing the Coastal Element of
the General Plan. A preliminary amount of these funds, esti-
mated to include up to $10,000, will likely be needed in the'
coming month to develop various feasibility studies in connection
with the Coastal Element. The remaining amount, $15,000, would
continue to provide a reserve fund for additional studies which
will bq necessary to complete this element of the -Plan -.-
With the introduction of the Noise Element, it appears that addi-
tional funds will likely be needed this coming fiscal year, 1972-73,
to incorporate the.element as part of the General. Plan. The Staff
would recommend that a total amount of $20,000 be requested to
complete the necessary work related to the Noise. -Element.

Dear Lou,
The City of Newport Beach is presently soliciting proposals
to perform studies leading to the Noise .El ement' of the
General Plan.
Attached'is a copy of the General PI -an Time Schedule which
covers the period between January, 1972 and July, 1973, the
anticipated completion date for the General Plan. Several
.of these dates are cri t'i cal, to the noise study and dictate
that the study be done in three distinct phases.
Phase One would consist of determining the ambient noise
levels in various areas in the community for different hypes
of land uses. In addition, the consultant would determine
and map the noise contours according to the guidelines
contained in Senate Bill No. 691 for all' 'ex1's'ti'n major
highways. (See attached map.) At the conc us}on of this
phase the consultant would make recommendations on how to
minimize the noise impact on various land uses. In order
to include these recommendations in the General Plan Specific
Policy Report, this phase should be completed by August 1,
1972.
The second phase would be to determine and map the noise
contours for ra'ected '1'eve1s of traffic on all existing
and" ro Used major ig ways and freeways. Conclusions
regar ing appropriate site.or route selection alternatives
or noise impact upon'Tand uses should be made for inclusion
in .the General Plan. This phase will begin approximately
January 1, 1,973 'and should be completed by lurch 1, '1973.
The time delay is due to the fact that the transportation
consultant will not start developing alternative highway
systems until October, 19.72 with completion' expected in
December, 19.7.2.

Phase Three would consist of developing a• noise ordinance

We hope that this brief discussion will answer any questions
that you may have. We are not presently budgeted for an
acoustical consultant. Therefore, we would appreciate
receiving your proposal as soon as possible in order that
we can take this matter to the City. Council during the course'
of their budget hearings to take place in May.

that the study be dons In thr$e distinct phases.
Phase One woul# consist of determining the aftient noise levels
in various araas in tha community for 4i fferent types of land
uses. in Addition, the consultant would determine and map
{
the noise ,contours according to the g•ui deti nas ,conta l ned In
Senates Dill No, 691 for all existing maj-or highways, (See

--EXHIBIT "A"
-SCOPE OF SERVICES
The study shall consist of two principal phases of work;
Phase I The Measurement and Analysis of
Existing Noise Levels
Phase IT The Projection and Analysis of
Future Noise Levels
PHASE I - MEASUREMENT AND ANALYSIS OF EXISTING NOISE LEVELS
This phase will involve four tasks. The first task shall be to determine and map
noise contours in accordance with the standards and guidelines contained in Senate
Bill 691 (California Government Code 65302) for the following major highways within
the City of Newport Beach:
Pacific Coast Highway
Mac Arthur Boulevard
Jamboree Road
Newport Boulevard
Balboa Boulevard (between Balboa Pier and Pacific Coast Highway)
Irvine Avenue
Campus Drive (between Mac Arthur Boulevard and Irvine Avenue)
Bristol Street (between Mac Arthur Boulevard and Irvine Avenue)
Cliff Drive (between Irvine Avenue and Riverside Avenue)
Riverside Avenue (between Pacific Coast Highway and Cliff Drive)
The noise contours shall be derived from actual field measurements and analytical
studies by consultant of the selected highway network. Such characteristics as
daily and seasonal traffic flow, traffic mix, highway width and grades, property
grades, and adjacent land uses, together with traffic noise measurements from
selected highway field stations shall be reviewed and analyzed by the Consultant
and summarized into a series of noise profiles for various hi�hway locations. From
these noise profiles, the Consultant shall develop CNEL (Community Noise Equivalent
Level) contours for the total highway network and all adjacent properties in con-
formance with the standards and guidelines outlined in Senate Bill 691.
Lity or Newport Beach
' ' }
To assist the Consultant in calculating the various noise levels due to highway
traffic, the City staff shall provide hourly traffic estimates for those major
highways listed above.
The second task under Phase I shall be to determine ambient noise levels in various
areas of the community for different types of land uses. Community noise field
stations shall be established for such. purposes and shall be so located throughout
the City as to measure a representative cross-section of varying land use types and
conditions within Newport Beach. The Consultant shall confer with City staff as to
the most appropriate location for the field noise measurement stations.
The third task under Phase I shall be to make recommendations on how to minimize the
noise impact of existing highway traffic on various existing and future land uses
within the City of Newport Beach.
Report
At the conclusion of the first three tasks outlined under Phase I, a report shall be
presented by the Consultant. This report shall contain the following items:
• Map of Newport Beach highway system with the annual CNEL contours
s Seasonal variation of the CNEL contours
• Typical values for A -weighted sound levels on contours
• Representative ambient noise levels for the various land use categories
• The backup field measurement data and associated procedures
• Sufficient explanatory text to set forth the goals, techniques and
results of the program
• Methods and effects of reducing noise exposure near highways by
varying the local correction factors (highway grade, property grades,
buffering and traffic start/stop variations) characterizing the highway.
The report will also summarize a general step-by-step noise reduction program
encompassing the definition, monitoring, and eventual alleviation of transportation
noise in the Newport Beach area.
The final task under Phase I shall be to measure, analyze and make recommendations
as to the impact of local police and military helicopter operations on the City of
Newport Beach. The task shall include:
a. A study of the flight
operations of police
and military helicopters
uty
of
ivewport
Beam
r . 0
operating within the city limits to determine the type of equipment
utilized and the details of the operational procedures. (The task
assumes operational data will be made available by th6 Appropriate
city and military agencies.)
b. The measurement of helicopter noise under controlled conditions. A
series of noise measurements will be made of typical equipment utilized
by the police and military to determine the noise characteristics.
The controlled conditions include takeoff, hover, flight and landing.
Measurements will be made at three typical locations for the police
helicopters and three locations for the military helicopters. (The
task assumes assistance Will be given by the necessary and appropriate
city and military personnel.)

At the conclusion of the fourth or final task as outlined under Phase I, the
Consultant shall present a memorandum report on the noise generated by helicopter
operations in the City of Newport Beach utilizing the data obtained under items
a. and b. above. This report shall include;
e A map showing the routes followed by military helicopters and
some typical routes followed by police helicopters.
• Projected CNEL contours for military helicopters in
Newport Beach.
e Typical A -weighted sound pressure levels associated with both
military and police operations.
• Recommendation as to possible alternate operational procedures which
could be followed by helicopters in order to reduce the noise impact.
r Suggested procedures for zoning and building construction to make
the land impacted by noise compatible for its intended use.
PHASE II - THE PROJECTION AND ANALYSIS OF FUTURE NOISE LEVELS
This phase will be to determine and map noise contours for projected levels of
traffic on existing and proposed transportation facilities, including highways,
freeways, mass transit systems, and ground air facilities. The specific highways
City of Newport Beach
to be studied in this phase include those previously listed under Phase I, and
the following major highways and freeways:
W San Joaquin Hills Road
Dover Drive (between Pacific Coast Highway and l7th Street)
Superior Avenue
Bayside Drive
Corona del Mar Freeway (Route 57)
Newport Freeway (Route 55)
Conclusions regarding appropriate site or route selection alternatives and noise
impact upon adjacent land uses shall be made for inclusion into the City's General
Plan.
In part, the Phase II calculations shall be made utilizing the data base on noise
profiles established for Phase I and the development of projected noise profiles
for field stations representative of highways and adjacent property and land use
characteristics for projected highway expansions and new freeways. A computerized
model shall be developed and manipulated by inputting changes in traffic flow,
traffic mix, and new topographic characteristics for adjacent properties to obtain
projected CNEL (and noise) levels.
Report
At the conclusion of Phase II, the Consultant shall present a report contai-ning
the following data:
A matrix showing noise reduction to be achieved in various land use
areas associated with potential alternate traffic and highway
conditions.
• A series of recommendations relating to proposed highways and traffic
conditions which would optimize reduction of the Newport Beach noise
environment.
• A map of Newport Beach with the CNEL contours for the recommended
projected traffic on existing and -proposed highways and freeways.
• Recommendations relating to zoning, types of building construction,
and techniques for shielding private residential and public facilities
to reduce the noise impact of future transportation facilities on
Newport Beach residents.

SUMMARY AND CONCLUSIONS
' i. Present California Administrative Code requires that an interior noise level with
windows closed, attributabie to outside sources not exceed an annual CNEL of
' 45 dB. Further, proposed residential buildings located within CNEL contours of
60 dB must show by acoustical analysis that this requirement will be satisfied.
Since a typical structure transmission loss of about 20 dB is reasonably character-
istic of California residential construction.,houses located outside the 60 dB
CNEL contour (where the CNEL is less than 60 dB) should thus have a nominal
safety margin of 5 dB. Residential locations significantly removed from major
' arterials in Newport Beach are generally quite satisfactory in this regard with
only a moderate degree of helicopter noise intrusion. The attached maps demon
' strate the intrusion of the 60 dB CNEL contour into the community in the vicinity
r'
' of any given arterial. An average penetration range of 200 to 500 feet is
characteristic.
In general this range will not change significantly in the future although noise
penetration from a larger proportion of the arterials will then fall in the upper
part of this range. An interesting special future case will be the projection of
60 dB CNEL contour 900 feet into the community from the Corona Del Mar
Freeway especially in the vicinity of the Bay View Intermediate School.
2. On a comparative basis relative to a range of hourly noise levels characteristic
of other urban residential areas in the United States, Newport Beach could be
considered as quite average or representative. If a worst case comparison is
made based on the hourly noise levels near the main arterials of Newport Beach
' in contrast to values obtained near major arterials nationally, Newport Beach is
significantly lower..
' t indicate that acoustic shielding of the first row of
3. Field experience appears o n g
houses, as well as cumulative distance, results in a satisfactory noise climate
' around most major arterials beyond the first row of houses.

' 4. Noise intrusion from military helicopters may cause some annoyance and resultant
complaints when: residence'5are located within 2400 feet of the flight path. How-
ever, the fact that there are no evening and night military flights significantly
reduces the impact.
Police helicopters operate until 2:00 a.m, and complaints have been received.
The Police Department records indicate that complaints greatly decreased in
' 1972 from the level of 1971 and further decreased in 1973, such that record
keeping was then discontinued. r

S. Highway traffic can be expected to remain a major source of noise pollution in
Newport Beach. cons iderationVW�ie given to the following abatement
'
measures:
a. Enactment of a local use type vehicular noise ordinance patterned after
California State law and its local enforcement to supplement the state
program. New vehicle performance is presently adequately controlled by
State law. However, experience indicates that during the summer especially,
Newport Beach experiences a signficant influx of inadequately muffled auto-
mobiles (such as "dune -buggies"). A+ local use law would aid in the abatement

of this nuisance.

air conditioning to permit constant window closure, etc.) for allgesidential
construction proposed within any 60 dB CNEL contour so that an interior con-
dition of 45 dB CNEL will be assured. kkIta CtTY s�}tK.hit•t?V,]StpyE,'"R►

1.0 INTRODUCTION
With the passage of Senate Bill No. 691, Chapter 775, the State Government
Code was amended to require that a noise element be included in local general plans.
This noise element was to quantify, in numerical terms, noise levels associated with
all existing and proposed major transportation elements. This act specifies that con-
tours be constructed to show noise levels being generated by these transportation
elements and also to show how this noise is propagated into the community. It was
further specified that the contours be quantified to reflect the time duration of the
noises being measured as well as the magnitude of the noises.
A survey has been conducted to determine the actual noise levels and corre-
sponding time durations that exist in the City of Newport Beach. A composite noise
scale, called the Community Noise Equivalent Level (CNEL), has been used to
report the levels measured at various locations within the community. This document
reviews some of the literature to develop criteria against which these measurements
may be evaluated to place them in their proper perspective. Some of the basic con-
cepts of acoustics are presented in an Appendix in a way designed to aid the average
citizen in understanding noise in a community.
Current traffic studies of the arterials in Newport Beach have been utilized
to show the present and future expected noise levels along these arterials. These
have shown that potentially annoying ground vehicle noises do exist within 50 to
100 feet of the arterials. Sound propagating further into the community are usually
Y
rendered inaudible by typical noises inside most homes. Overpowered and under--
ft
muffled vehicles provide an inevitable exception to this desirable condition.
,1 Another major noise source is commerical jet aircraft operating from Orange
County Airport. This topic is covered in a previous report (Wilsey and Ham, Project
Consultant, "Orange County Airport Impact Study, " April 1970).

2.0 MEASUREMENTS OF PRESENT DAY HIGHWAY NOISE IN NEWPORT BEACH
' the standards and guidelines contained in Senate Bill 691
To comply with
(California Government Code 65302), measurements have been made of the sound
pressure levels found at curbside at several locations within the City of Newport Beach.
Noise from highway vehicles can be specified in several ways:
• The maximum noise level during passby of a single vehicle
• The time -integrated noise level during such a passby known as Single
' Event Noise Exposure Level (SENEL)
0 The average (on an energy basis) noise level over an hour known as the
' Hourly Noise Level (HNL)
' • The composite 24-hour measure of noise known as the Community Noise
Equivalent Level (CNEL)
' The first two measures are useful when considering general annoyance to dis-
turbing single intruding sounds. The last measure, which utilizes the third (HNL}
' measure, is more often used for evaluating long-term response of a community to
intruding noises. All of these measures of noise will be utilized, where appropriate,
' in this report. A more detailed definition of community noise scales is given in
Appendix A.
' The current noise levels existing along the highways of Newport Beach have
been reported in Reference 1 and are briefly reviewed here. Figure 2--1 is a map
' showing contours of constant CNEL derived from measurements of HNL during the
Fall of 1972. The conversion to CNEL from HNL has been accomplished through the
use of traffic distributions measured during the Summer of 19721 and older traffic
studies completed in 1968 5 The new map is quite similar to Figure 1 of Reference 1,
1 since the conversion between HNL and CNEL amounted to 0 to 2 dB, the difference
' depending on the relative levels between nighttime and daytime levels. Where the
nighttime levels were 10 dB or so lower than the daytime levels (Irvine and Francisco,
1 Cit of NeWport BeaC�,YLE LA®ORAT..1E5Y
1
P ELIMI[�`ARY*
for example), the CNEL is approximately equal to the daytime HNL. Where nighttime
' levels are high (Pacific Coast Highway and Dover), the CNEL is approximately 2 dB
' above the daytime HNL.
Examination of the map will show that CNEL values above 60 decibels may be
found at most locations within one block of any of the main arterials.
The Pacific Coast Highway exposes large numbers of residences in the Corona
' Del Mar and Irvine Terrace areas to relatively high traffic noise. All of this area is
also between the 55 and 60 dB range for the military helicopters from El Toro U.S.
Marine Corps Air Station. Contours from the two noise sources (highway and helicopter)
are separated on the map, but it must be realized that these contours actually contribute
to each other. Thus, at the corner of Pacific View Drive and MacArthur Boulevard,
the automotive 55 dB contour intersects the helicopter 60 dB contour. These levels add
' together to produce an actual level of 61 dB CNEL. (Noise levels add on a logarith-
mic basis as explained in Appendix I.) Two equal noise levels, added together, add
' to a level 3 dB above either one alone. This condition occurs where both levels are
identical such as at Morning Canyon Drive where two 60 dB CNEL contours intersect.
2.1 Some Typical Traffic Noise Levels in the City —Measured and Calculated
row
Figures 2-2 through 2-6 illustrate the Hourly Noise Levels (HNL) at various
9 g
1 locations within the City during a single 24-hour period during the Summer of 1972.
Figures 2-7-through 2-10 show calculated traffic noise levels from traffic measurements
made during 1968? The levels reported in Figures 2-2 through 2-6 represent the sound
pressures found at the curb of the streets listed on the figures. Again, busy areas such
as Pacific Coast Highway at Dover Drive and Newport Boulevard (Figures 2-»2 and 2-3)
show constant levels throughout the 24-hour day with less than a 10 dB total variation.
Figure 2-4 shows some variation with traffic decreases between 1:00 and 6:00 a.m.,
but even here there is only 13 dB variation between the low and high points during
the day. Greater variation is seen at Jamboree and Ford Roads and Irvine and Francisco

' (Figures 2-5 and 2-6). These locations become quieter at night and only an occasional
vehicle will pass by during the early morning hours. Variations above 15 or 16 dB are
common on these streets. Figures 2-7 through 2-10, showing calculated noise levels
derived from traffic data, indicate similar results. These latter figures contain noise
levels calculated from both summer and winter traffic. They graphically illustrate the
tendency for lower traffic levels and hence less noise at night in the winter. This is
particularly obvious at Balboa Boulevard and Pacific Coast Highway, as reported in
Figure 2-7.
2.2 Propagation of Traffic Noise into the Community
All the levels reported in Figures 2-2 through 2-10 were measured or calculated
at curbside. Where there are no barriers to the sound fields, such as store fronts, walls,
' hills, or other solid partitions, the sound levels may be expected to attenuate by approxi-
mately 4 to 6 dB in the first 50 feet of distance. (This is commonly known as spreading
' loss.) The existence of barriers may reduce the nearby levels, by an additional 10 to
15 dB. At'distances beyond 200 feet, the effects of such barriers are small. However,
the normal spreading losses at 200 feet will generally reduce the traffic noise to less
than 60 dB, thus, normally removing any cause for concern. Other effects, such as
temperature inversions and winds, will tend to cause fluctuations in the noise levels.
Measurements were made to determine the decay of sound as it propagated into
City residential areas from the arterials. Most of these measurements were conducted
with an artificial noise generator which simulated the frequency content of traffic
noise from a single simulated vehicle rather than through measurement of the actual
traffic noise. This allowed measurement of the sound signal at much greater distances
than would have been possible using the traffic noise alone. Figure 2-11 illustrates
A
the sound attenuation characteristics of the simulated traffic noise at site where no
obstacles were present. When shallow hills existed between the source and receiver,
considerably more attenuation was measured. Buildings and other sharp obstacles in
' the source -receiver path effectively reduce annoyance from noises generated at
' curbside.

3.0 NOISE ENVIRONMENT COMPARISONS AND APPLICATION OF NOISE
' CRITERIA TO NEWPORT BEACH
1
1
A measure of the noise found at a given location takes on meaning only when
it can be related to some criteria for acceptable levels or to noise data from other
locations as a basis for comparison.
Different noise criteria are recognized for the following purposes: maximum
noise levels safe for human hearing — damage prevention; maximum noise levels to
avoid interference with speech communication and sleep; and the varying degree of
community response to an integrated 24-hour measure of noise exposure (i.e., CNEL).
'
The concern here is only with the last two criteria, since there is no evidence
that outdoor noise exposure in any residential area in Newport Beach approaches
1
levels potentially damaging to hearing.
3.1 Levels Found in Other Parts of the United States
'
Hourly Noise Level (HNL) measurementssin the City of Newport Beach are
'
plotted as cross -hatched areas in Figure 3-1, where they are compared with shaded
areas representing the approximate range of Hourly Noise Levels over a 24-hour
p g pp
'
period found at several locations in the United States as reported in Reference 3. The
•
general noise levels from Reference 3 are restricted to normal public places so that
'
extremely noisy environments have been left out. The area labeled "arterials"
includes HNLs measured over a range from a point 100 feet from the San Diego Free-
'
way to busy through -streets in downtown Los Angeles and New York City. The area
labeled "urban residential " is an envelope of the Hourly Noise Levels found in a wide
'
range of typical urban residential areas.
The rural area includes noise levels for close -ended streets in small towns, as
well as actual farm land during a time when agricultural machinery is not operating.
The bottom limit of the rural area was measured in a wilderness area away from almost
all man-made noise other than occasional overflights of planes. The extremely low
noise levels in this wilderness area were heavily affected by the noises of nature.

PRET.IMINHI�Y
The Hourly Noise levels observed in eight locations, in each case covering a
24-hour period, in Newport Beach are superimposed upon this figure. The locations
near arterials in Newport Beach are seen as the cross -hatched area falling between the
two upper areas of the figure. This demonstrates that the noise levels near busy arterials
in Newport Beach are substantially lower than those in large cities. The hatched areas
representing the residential areas of the City fall directly in the full range of residential
areas for other parts of the United States and are, thus, no better or worse. None of
the areas in Newport Beach are as quiet as the rural areas.
These eight locations in Newport Beach at which the data was taken which
formed the basis for the comparisons made in Figure 3-1, are listed in Table 3-1,
' together with their daily CNEL levels. The CNFL levels for the arterials have been
corrected from the levels actually measured near the curb to correspond to a uniform
' distance of 50 feet from the curb.

The correction from curb level to a position 50 feet away results in the level
that would be found just outside the homes of many people living near arterials such
as Irvine Boulevard.
3.2 Levels Causing Community Response
An additional indication of the relative acceptance of the normal outdoor
tnoise levels measured in Newport Beach can be gained by comparing these levels with
the levels which produce varying levels of community response. An indication of the
' community response level versus CNEL is reproduced from Reference 4 as Figure 3-2.
This figure gives a scale of normalized CNEL. The normalization procedure consists
' of adding correction factors to the measured CNEL to obtain the normalized CNEL.
These factors are given in Table 3-2. Two examples of the application of these
' factors to the measured values of the Average Hourly Noise Levels of the intruding
noise are given in Table 3-3. The examples are drawn from the results at two actual
locations in Newport Beach and illustrate an approximate procedure for calculating
CNEL from the measured averages of HNL in the daytime, evening, and nighttime
' periods, accounting both for the weightings of 0, 5, and 10 dB, respectively, and
for the duration of each of the periods. In the case of the first example at Hospital
' Road, there are no residences within 50 feet of this location so the widespread com-
plaints mentioned would not be expected to occur.
' The data of Figure 3-2 show no observed reaction for normalized CNEL values

from 50 to 60 dB with a median at 55. However, an average normalized CNEL of
60 dB may cause sporadic complaints. This apparent discrepancy may be resolved by
reference to the ambient noise in a given community. When the intruding noise does
not significantly exceed the ambient noise, few complaints are heard. When the
intruding noise exceeds the ambient by about 17 dB, complaints may be expected.
It is easy to see where a CNEL of 60 dB might be 17 dB above the ambient in one
locale and at the ambient noise level in another. In the case of traffic noise on an
established arterial, such as Irvine Avenue, the traffic noise is the ambient noise and

complaints are few, occurring only when particularly noisy vehicles cause loss of
sleep or other similar circumstance.
Figure 3-2 suggests that if noise complaints within the community are to be held
to occasional or sporadic complaints, then the mean normalized CNEL values should be
' held to 60 dB or lower. It is seen that levels below 55 decibels will not elicit complaints
from the general public (mean values on the curve), but that some people will be dis-
turbed by even this low level.
It may be concluded, therefore, that it is desirable to limit traffic noise in a
1 residential community to CNEL values between 55 and 60 dB, with preference given
to CNEL 55. In Newport Beach, this criteria is currently met only in the quiet resi-
dential areas well separated from arterial traffic. A community oriented to industry
and the attendant heavy traffic might determine that a CNEL of 70 dB would be accept-
able to the general populace.
3.3 Levels Causing Speech Interference
A third criteria that may be applied to noise may be obtained by consideration
of the speech interference caused by a given level of A -weighted noise. Figure 3-3
again taken from Reference 4, shows the allowable distance between a talker and
' listener as a function of the interferring background noise level for various degrees of
vocal effort. Thus, if the background noise level is 70 dBA, normal conversation may
be carried out at a distance of 3 feet or less. Shouting will extend this communication
distance to about 17 feet. At higher noise levels and/or greater distances, communica-
becomes difficult, with the loss of large percentages of the word syllables. The levels
of this figure are not time averages, but actual levels existing at the time speech com-
munication is going on. If two persons were standing at the curb at Pacific Coast
' Highway and Dover Drive, they would find the A -weighted levels exceeding 87 dB
10 percent of the time.i Thus, they would find it necessary to stand within 3 feet of
each other and use a loud voice to communicate.

4.0 FUTURE SOUND PRESSURE LEVELS IN NEWPORT BEACH
Sound pressure levels in the City of Newport Beach and environs for the future
are reported in Figure 4-1 as contours superimposed upon a map similar to Figure 2-1.
Projections of noise levels from the various streets and freeway rights -of way are based
upon a map of projected traffic volumes provided by the Advanced Planning Division of
the Community Development Department of the City of Newport Beach.
' 4.1 Projection Criteria
' Since the "Traffic Volume "map does not break down traffic into hourly incre-
ments, it has been necessary to make several assumptions about future traffic in order
' to predict CNEL levels. These assumptions are:
1. Truck traffic will be approximately 10 percent of the total traffic on
the streets of Newport Beach, both day and night.
2. Given an Average Daily Traffic Count, it is assumed that 87 percent
of the vehicle count occurs between 7:00 a.m. and 10:00 p.m. with
the remaining 13 percent during the other 9 hours of the day. (These
percentages represent averages taken over many areas of the U.S. at
different times of the year.)
The noise measurements conducted in Newport Beach by Wyle Research indicate
that truck traffic should be weighted approximately three times as heavily as automobile
traffic in determining its relative importance as a noise generating mechanism in the
' City. The weighting factor of 3 is much lower than usual due to an unusually high
incidence of relatively poorly muffled recreation type vehicles such as "dune buggies"
especially in summer. This is actually an unnecessary nuisance as adequate muffling
in no way deteriorates performance to a point of inadequate safety. The preponderance
1 of data taken in other areas of California and in other states has indicated that a factor

State law. The calculations which result in Figure 4-1 assume that in the future this
' anomaly will be abated and the more common ratio will hold.
One other aspect of noise studies in the City of Newport Beach concerns the
assumed percentage of vehicles traveling during daytime hours. As was shown in
Figures 2-7 through 2-10, this percentage changes between summer and winter. The
' 87 represents resents averages taken over many areas of the United States at different
P P g
times of the year. Reference 2, Table I, lists hourly traffic at various locations in the
City for both winter and summer. This table indicates that the daytime usage during the
winter is about 91 percent, and that it drops to around 83 percent during the summer.
Again, however, the average for all locations for both winter and summer is 87.7 per-
cent, so that the "national " average of 87 percent seems well justi Pied for use in
Newport Beach.
4.2 Discussion of Noise Contours
Figure 4-2 indicates the way A --weighted Hourly Noise Levels decay with
distance. This data has been used to determine the actual location of each contour
' when the roadway is assumed to be level with the surrounding ground. If a roadway is
elevated, the high level contours (70 and 65 dB curves) will move in. This is because
' the edge of the road will shield some of the car noise very close to the road. At greater
distances (such as the 60 decibel contour), this shielding does not occur and the raised
' roadway does not offer any reduction.
In areas where a roadway is depressed, there will be a 5 or 6 dB reduction of
all levels. Short sections of depressed roadway do not offer much advantage, but a long
section would give this desirable effect. For instance, the entire campus of the Bay
View Intermediate School would be outside the 55 dB contour instead of inside it if the
Corona Del Mar Freeway were depressed within the city limits. Residents around the
San Joaquin Reservoir could be given similar advantages by a depressed freeway.

It may be noted that contours on Figure 4-+1 have been extended to 60 dB
rather than the 65 required by the California statute. This was done because some
complaints may arise at the 60 dB level. Also, California Administrative Code requires
an acoustical analysis for approval of residential construction within 60 dB CNFL contours.
Some areas outside the city limits are also treated because of the effects these areas will
have upon the City.
The map scale used for these contours is small, and it is impossible to determine
close details from the map. Figure 4-2 has been prepared to show the variation of
CNFL with distance from a roadway for several different traffic levels ranging from
20,000 to 135,000 vehicles per day. The curves are valid at a speed of 60 miles per
hour. Each level will drop 3 dB at 48 miles per hour or increase 3 dB at 75 miles per
hour.

5.0 HELICOPTER NOISE IN NEWPORT BEACH
5.1 Police Helicopters
The City of Newport Beach operates two police helicopters for surveillance of
areas sensitive to crime. These craft have no set pattern of operation and might be
found at any point at any time. During emergency situations when the helicopter is
moving to a scene of action, noise generation is quite high, but duration and frequency
(as seen by an given resident under the flight path) are very low.
Reference l lists the measured sound pressure levels at ground surface for 500r
800, and 1500 feet at four different locations in the City. The measured A -weighted
sound pressure levels average 70, 65, and 60 dB respectively at these flight heights.
Table 5-1 lists the three different operating conditions together with, a pro-
gression to CNEL figures under some different assumed flight patterns.

6.0 ABATEMENT OF NOISE
Noise abatement can follow several procedures. There are, of course, certain
procedures which have been preempted by the State and Federal Governments so that
the City cannot use them. The most obvious of these is aircraft noise, which is con-
trolled by the Federal Government.
The major methods of noise abatement open to the City are:
1. Enact and enforce use laws on vehicle noise
2. Encourage the use of depressed roadways or barriers
3. Enforce zoning regulations
4. Enforce building regulations

There are presently state laws limiting the maximum noise that may be radiated
by vehicles. A truck may not generate more than 90 dBA at a distance of 50 feet on
any state-controlled roadway such as the interstate freeway system. The California
Highway patrol presently has five teams in the State operating sound level meters to
determine sound levels from trucks and cars on the freeways. These teams have, on
occasion been used in individual cities where loud vehicles are found, and warning
citations have been issued. However, this does not preempt the right of the municipality Vil
to enact and enforce local use laws. Since, continuous support by the state police is he
G
not practical, the feasibility of local enforcement of an equally strict code should be
considered.
Barriers
A roadway may be depressed to allow cross streets to maintain their previous
elevation and appearance. Such a depression of the roadway also assists in reducing the
noise level'in nearby residential areas, and should be utilized to the fullest practical

' extent. Reductions of up to 20 dB may be obtained, but 10 dB is the usual attenuation
of reasonably sized barriers.
' Zoning Regulations
' Zoning to assure compatible use of land within the City will always remain the
most forceful noise abatement tool in the hands of the city planners. potentially noisy
' areas that may be controlled through zoning regulations include industrial areas between
Jamboree Road and MacArthur Boulevard and along Campus Drive near the airport.
Where industry is placed in the Jamboree Road area, assurances of noise control must
be obtained for the Back Bay area and the Corona Del Mar High School. The light
' industry characteristic of the Newport Beach area will generally not pose any problem
to these areas. The attenuation characteristics of Figure, 4-2 for highway noise suggest
that distances of the order of 1000 feet will severely attenuate a given noise source
without barriers or any other noise control measures. If high intensity noise, such as
' would be found with power saws or large steam or air valves were present, more atten-
uation would be required. Individual installations should be examined by persons trained
Ito evaluate noise control problems.
' Building Regulations
Application of improved building code requirements for higher outdoor -to -
indoor noise reduction for homes or multifamily dwellings very near highways should
be recognized as one practical element of noise abatement. Well established technology
is available for implementing this technique of noise abatement.
Present California Administrative Code demands an acoustical analysis for all
proposed.,residential construction to be performed within 60 dB CNEL contours. The
contractor must show that employment of techniques such as use of special topological
features and provision for adequate structure transmission loss by use of a forced
ventilation system (with permanently closed windows) will assure year -,round achieve-
ment of an interior CN£L of 45 dB.

1 APPENDIX I
A SHORT PRIMER ON NOISE AND COMMUNITY NOISE SCALE
For the benefit of the reader, this Appendix provides a short primer on noise and
defines, qualitatively, the noise scales used in the report.
Generation of Sound
Sound in the air is generated by forces acting on the air molecules. This may
result from a complicated interaction of air leaving an exhaust pipe or something as
simple as a panel vibrating against the air. Whatever the mechanism, the result is
that at any one instant, the air will be slightly compressed at one point and will be
' rarified at another point. This pattern of pressure disturbance moves through the air
as a sound wave. Figure I-1 presents this concept in the case of the vibrating panel
' driven by an eccentric shaft and rod. As the panel moves to the right, air is com-
pressed and as it moves to the left, air is decompressed or rarified. This effect
continues with time and a pressure wave is transmitted into the air. Thus, a rare-
faction wave progresses to the right as a result of the panel moving to the left. As
' the panel moves again to the right, another compressional wave is generated and
the distance between two successive compressional waves is called the wavelength.
Noise -- How Do We Describe It?
Noise is usually defined as unwanted sound. One person's music may be nothing
but noise to another. For example, the sound of rock music from your teenager's
hi-fi may be music to him or her, but noise to you, if you are trying to converse or
relax in an adjoining room. To describe noise and its effect on people in a quanti-
tative way, we must include human factors related to the way we perceive noise.
These factors include differences in the way our ears hear sounds at different fre-
quencies, whether the sound contains any irritating "screech" like squeaky chalk on
' the blackboard and how long the sound lasts. Applying all these factors enables us

to translate from a physical measurement of a sound to its value on a subjective,
"perceived noise," scale.
' Acoustic levels that we normally experience are very small compared to the
usual static (or barometric) pressure in the atmosphere. An acoustic pressure of 1
' microbar would be average for normal conversational speech tones. This pressure is
equal to 1/1,000,000 of the usual barometric pressure of 14.7 psi. Thus, at a time
and place where the atmospheric pressure was exactly 14.7 psi, the total peals pres-
sure during average speech would be 14.700021 and the minimum pressure would be
' 14.699979 psi. The decibel scale (discussed below) would specify this very small
pressure fluctuation as 74 decibels. At 134 decibels, a sound level much higher
' than normal experience, these two pressure extremes would be 14.721 and 14.679,
respectively. In this example, the acoustic pressures have changed by a factor of
1000 with an insignificant variation in the total atmospheric pressure.
' The Decibel
An explanation is in order regarding some basic properties of any scale for stating
the magnitude of a sound. The ear responds to sound pressure fluctuations with an
increased sensory response for an increase in pressure. The range between the smallest
' sound pressure which is sensed by the human ear and the highest sound pressure physically
tolerable covers a ratio of approximately 1,000,000 to 1. If we assign the number 1
tto the sound pressure coresponding to the smallest sound that we can hear, then the
sound pressure from our voice in quiet conversational tones would correspond to the
' number 1,000. A loud voice would be approximately 30,000, and physical pain would
be felt in the ear at a sound pressure over 1, 000, 000.
' While our brains have no trouble handling the range of sounds sensed by our ears,
it is inconvenient for us to think in terms of numbers with all these zeros. It becomes
more convenient, therefore, if we base our scale on the number of zeros rather than
the actual number. The logarithm to the base•10 does just this. Thus, we may assign
City of New'-'portAT BeachYLE LABORATORIES
the zero on our scale to the number we can just hear, since the logarithm of 1 is zero.
Our quiet conversational tones will then be assigned the number 3, since the logarithm
of 1,000 is 3, and the highest pressure mentioned above (1,000,000) would receive
the number 6.
'
All of the numbers assigned -- 1, 3, and 6 -- are equal to the logarithm of the
actual numbers, and the quantity measured in such a scale is called a level. Engineers
and scientists prefer to work in terms of energy, which is proportional to sound pressure
squared instead of sound pressure. Thus, all the above numbers for sound pressures
!,
must be squared. Making this adjustment, 1 squared becomes 1; 1,000 squared becomes
1,000,000; and 1,000,000 squared becomes 1,000,000,000,000. Fortunately, the
'
logarithm of a squared number is just two times the logarithm of the number; so, instead
of the level ranging from 0 to 6, it ranges from 0 to 12. This scale is similar to the

smaller units, so that the scale of level now extends from 0 to 120 decibels or tenths
of Bels.
Figure I-2 provides an illustration of these concepts for converting from an incon-
venient magnitude scale (linear pressure) to a more convenient scale of level (loga-
rithmic) with decibels as the units. Utilizing this basic idea of a level scale,
acousticians have invented a profusion of different kinds of levels, all in decibels,
abbreviated dB. The most.common of these is the "sound pressure level" defined by:
Sound Pressure Level (SPL) = 10 log10 (p/preference)2 in dB
Preference is the reference pressure equal to .00002 newtons per square meter
which is the same as 0.000,000,002,9 pounds per square inch. This reference pressure
was chosen as being near the smallest sound pressure that we can hear. It sets the
location of the zero on our basic SPL scale.

The Frequency Content or Pitch of Noise
While the magnitude of a sound pressure is of primary importance, its frequency
or pitch is also a primary consideration. The frequency or pitch of a sound represents
the rate of oscillations of the acoustic pressure. The human ear is less sensitive to low
frequency sounds and very high frequency sounds than it is to mid -frequency sounds.
The frequency limits of audible sounds extend from 20to 20,000 Hz (cycles per second).
The moving panel of Figure I-1 may move back and forth 20 times or cycles each second
to create a 20 Hz acoustic signal or 1000 times each second to create a 1000 Hz signal.
The lowest note on a moderately large pipe organ will be 32 Hz, and the highest note
from a piccolo will be around 4700 Hz. Overtones from each of these instruments will
extend to beyond audibility. As mentioned above, however, the ear is not equally
sensitive to all these frequencies. The ear is 50 dB less sensitive at 20 Hz than it is at
1000 Hz. Figure 1-3 demonstrates the different sensitivity of the ear at different
frequencies and shows how it affects a given sound spectrum, happily reducing the
annoyance caused by low frequency noise. Figure I-3(b), showing the allowance for

human hearing, has been defined as the "A" weighting scale. Electronic filters
having this frequency response have been incorporated in most sound measuring equip-
ment. When such filters are used, the resulting reading is said to be "A" weighted
or "A" scale. Use of these filters allows us to determine a single decibel number
which, to some extent, represents human response to a given noise.
Time Factors in Defining Noise Environments
So far we have talked only about the magnitude and frequency of noise along
with the decibel scale with which we measure the magnitude. The perceived level
(that is -- the way our brains react to it) that we subjectively apply to a noise seems
to depend upon its duration also. In addition, the actual annoying effect of the sound
may depend on the time of day as well. This time of day sensitivity simply relates to
our daily cycle of activity. In other words, a short loud blast of a whistle announcing
noon (and lunch) would not be found so irritating as a less intense noise sounding over
a period of several hours during the day. The some short blast, or even the long duration
"less intense noise" might be found quite irritating during the middle of the night when
we are trying to sleep. Thus, in order to produce a rating scale for the annoying effect
of noises we consider, in addition to the level and frequency content, the duration
of the sound. Further, we attempt, in a crude way, to account for varying inter-
ferences with our daily life. We therefore consider the time of day during which the
noise is generated.
Sound waves are a form of energy just like electricity and light. The rate of
release of energy or power may be measured in terms of kilowatts just as electrical
power is. The power associated with acoustics within our normal experience is quite
small compared with the power available from the electric lines. Where a very small
electric light bulb will use 25 to 30 watts of electricity, normal conversational speech
power will be around 27/1,000,000 watt10 and where a powerful hi-fi is pouring
100 watts. into a loudspeaker, little more than 1/4 to I watt of acoustic power is
Ir7
Cityof Newport Beac WYLE LABORATORIES

1
being generated. Even so, this little bit of power is -more than adequate to shake the
windows and rouse the neighbors.
' The acoustic power generated by earlier models of commercial jet aircraft far
exceeds the output of the hi-fi or even the 80 or so watts produced by an energetic
' orchestra in concert. These craft will generate as much as 40,000 watts at full take-
off throttle. It is possible for a person to briefly generate as much as 1/10 watt and
' a trained singer can approach a full I watt acoustic output for a short time.
It is possible to convert acoustic power into a flow of heat and this may be
accumulated as heat energy. If this energy can be contained so that it can be
accumulated over a long period of time, the normal conversational tallier can heat
up a cup of tea in 34 years or 100,000 football fans could, conceivably, do it in 4
seconds. The point is that it is possible to measure noise in terms of the time inte-
grated (accumulated) measure of noise intensity. This will result in a measure of
total acoustic energy. The reasoning behind this measurement is that people seem to
react to the total energy of noise environments rather than to only the power generated
by single events. Thus, it is desirable to define fluctuating noise environments in
terms of the constant noise level which generates the some energy. This is done to
obtain an average level over a given period of time, nominally one hour. The Hourly
Noise Level (HNL) can thus be defined as the total acoustic energy found at a given
point over a one hour period divided by the number of seconds in the hour. Again,
the decibel scale is used and it is defined such that the HNL of a steady tone is the
same as the SPL (sound pressure level).
The end result of all this is just to say that a loud noise for a short time may
' receive the some raring as a soft noise over a long period of time. The some HNL
reading would be obtained if one truck passed by and generated a noise level of 88 dB
for 10 seconds or 78 dB for 100 seconds. If ten trucks, each making 88 dB for 10
seconds, went by during the hour, an HNL meter would read 73 dB — a tenfold
City of New'_'port BeachYLE LABORATORIES
increase in noise energy represented by a 10 dB increase in the Hourly Noise Level.
Thus, 100 such trucks would give a reading of 83 dB and 1000 of them would increase
the level to 93 dB, and so forth.
Community Noise Equivalent Level (CNEL)
So far in our example, nothing has been said about the time of day the trucks
' were going by. The time -integrated measure of noise which attempts to account for
this time of day sensitivity is called the Community Noise Equivalent Level. It is
'. developed in the following way. Early studies of community noise exposure indicated
that one intruding sound during the evening hours will be approximately as annoying
' as three occurrences of the same sound during the day. During sleeping hours at night,
this time -of -day penalty seems to be about 10. The factors of 3 and 10 are only
' approximate, but they seem to give a reasonable accounting of the weighting that
should be applied for evening and nighttime noises. The times have been customarily
' specified for daytime, evening and nighttime and are 7:00 a.m. to 7:00 p.-m., 7:00
p.m. to 10:00 p.m. and 10:00 p.m. to 7:00 a.m. respectively. Therefore, if 33
' trucks passed by during the evening hours, they would be counted as 100 trucks and
given the some effective HNL value of 83 dB as the 100 trucks during the daytime
hours (add 3 dB for three times as many and 10 dB for 10 times as many). During night-
time hours, only 10 trucks would be counted as equivalent to 100 trucks and would
_ r yield the same HNL effective value of 83 dB. Thus, the noise energy is defined in
terms of the Hourly Noise Level for each hour of the day. This energy for each hour
' over the entire day, after having been appropriately weighted to account for the time
of day as above, would be added together and divided by 24 to give the weighted
average noise level for the day. When expressed in decibel form, this number is
called the Community Noise Equivalent Level (CNEL). It provides a single number to
show the relative noisiness of a given location on a given day. Generally, this
number does not vary substantially at a given community location over a period of
weeks. In areas where there are large variations in seasonal traffic, there will be
seasonal variations in the CNEL. When the CNEL is dominated by highway traffic,
1 CityNewportof Beac4.L.
LAgORAT�RIES
as it often is, the traffic must double to effect a 3 dB change in the CNEL. An annual
average of the daily CNELs for a given area would tend to exhibit little change from
year to year, providing the nearby land use and traffic flow do not change markedly.
Single Event Noise Exposure Level (SENEL)
1 The Single Event Noise Exposure Level is also dependent upon time, but it is
somewhat different in its application. Essentially, it is designed to determine the total
1 acoustic energy associated with a single event such as would be generated by the
' passage of a single vehicle or aircraft. A flyby of a single aircraft will cause the
acoustic level to gradually rise, reach a peak and then fall. The total area under a
curve representing this flyby is proportional to the SENEL. The SENEL differs from the
other measures discussed above in that they are averaged in time. That is, the total
' energy is divided by the total number of seconds required to make the record. The
main difference between these two records, then, is that an SENEL will always result
1 in a number that is higher than the peak level measured and will represent a single
event, while an HNL (or CNEL) will always result in a number that is lower than the
peak levels measured and will represent the integrated energy -average level for all of
the events than occurred during the time period specified by the measurement (one hour,
' one day, or one year).
An approximation of SENEL may be obtained by the following procedure:
1 1. Obtain a level versus time trace of the sound pressure level (SPL).
2. Determine the time duration in seconds that the SAL is within 10 dB
of the peak SPL.
3. Determine the logarithm to the base 10 of this duration (characteristic
and mantissa); multiply this logarithm by 10.
4. Add the number found in step e 3 to the peak SPL. Subtract 3 dB.
This is the approximate SENEL.

level meter, drops from its maximum value to 10 dB below that level, a rough approxi-
mation of SENEL may be obtained by adding 10 times the logarithm of the number of
seconds to the maximum noise level.

SUMMARY
This program was sponsored by the City of Newport Beach in compliance with the stan-
dards and guidelines contained in Senate Bill 691 (California Government Code 65302).
This code required that any new general plan of incorporated cities include a noise ele-
ment to consist of weighted noise level contours generated to show transportation noise
related to the various highways, freeways, rapid transit systems and airport ground
facilities. The data is to be weighted to show total energy; that is, a scale must be
used which includes duration of sound as well as amplitude.
This report provides the required noise contours due to highway vehicles for the major
streets in the City of Newport Beach. The contotr s have been developed, in part,
with the support of measurements of the integrated "A" weighted sound levels taken at
curbside for a number of locations within the city. These are augmented by two different
types of measurements to determine level versus distance from the roadway. The largest
number of these measurements was made using an impulse noise generator capable of
simulating the spectrum of vehicle noise and radiating very high sound pressure levels so
that measurements could be made at reasonable distances. This impulse generator was
supplemented by a measurement of the integrated "A" weighted traffic noise using five-
minute samples. The principal results of the study are illustrated in Figure I by the
estimated noise contours for highway vehicles only.
Some helicopter noise measurements have been made for both police and military fly-
overs, but routes flown by these vehicles are sufficiently variable that predictions of
noise produced in certain locations is not possible.

ENABLING LEGISLATION
This report is to fulfill the acoustic requirements of Senate Bill 691 (California Govern-
ment Code 65302). The specific requirements of this bill are as follows:
(g) A noise element in quantitative, numerical terms, showing contours
of present and projected noise levels associated with all existing and proposed
major transportation elements. These include but are not I imited to the
following:
(1) Highways and freeways,
(2) Ground rapid transit systems,
(3) Ground facilities associated with all airports operating under a per-
mit from the State Department of Aeronautics.
These noise contours may be expressed in any standard acoustical scale
which includes both the magnitude of noise and frequency of its occurrence.
The recommended scale is sound level A, os.measured with A -weighting net-
work of a standard sound level meter, with corrections added for the time
duration per event and the total number of events per 24-hour period.
Noise contours shall be shown in minimum increments of five decibels
and shall be continued down to 65 dB(A). For regions involving hospitals,
rest homes, long-term medical or mental care, or outdoor recreational areas,
the contours shall be continued down to 45 dB(A)•
Conclusions regarding appropriate site or route selection alternatives or
noise impact upon compatible land uses shall be included in the general plan.
The state, local, or private agency responsible for the construction or
maintenance of such transportation facilities shall provide'to the local agency
producing the general plan, a statement of the present and projected noise
levels of the facility, and any information which was used in the develop-
ment of such levels.

INTRODUCTION
The following report details the procedures and results of Wyle's efforts to accomplish
the objectives of the foregoing tasks. A map of Newport Beach has been generated to
show the hourly noise levels expected on the main highways of the City forming a rough
triangle around the Upper Newport Bay. Additional highways surround the lower Bay.
These levels have been specifically related to traffic count taken at the time the levels
were measured so that any given traffic data, at any time of day or year, may be trans-
lated into average noise levels covering any specific period covered by the traffic data.
Such conversions are detailed by both first and second order approximation techniques.
Correction factors are developed which will predict traffic noise conditions for streets
other than those studied when the proper criteria are applied to those streets. A term
has been used to define the acoustic average energy that a given location will exper-
ience when an average car or average truck passes that location once each hour. This
term has been shown to be relatively constant with reasonably small correction factors
for high speed, starting on a hill, long periods of idle in traffic jams, etc., to make it
even more closely approximate the average automobile at a given location. It is
called HNL* and is mathematically defined. Typical A -weighted noise levels at curb-
side have been tabulated. The daily Community Noise Exposure Level has been
measured by a sampling technique in five noisy locations and three quiet locations
within the City.
Seasonal variation of the Community Noise Exposure Level has not been established
because of lack of information on traffic variation, but methods are shown to accomplish
estimates of this variation.
Measurements of the decay of sound from the highways into the community have been
accomplished by pulse techniques. Information is given to demonstrate the validity of
these techniques as applied to the environs of Newport Beach.

MEASUREMENT AND ANALYSIS OF HOURLY NOISE DATA
Several different types of noise measurements were made during this program to establish
the noise levels in various areas of the City of Newport Beach. The first measurements
made consisted of one hour recordings of curbside noise levels as shown in Table I

The Hourly Noise Levels (HNL) shown in Table I were derived by use of a computer to
determine the time in tenths of a second that the sound pressure level was at any given
level. The levels were divided into one -decibel increments so that a count was made
10 times per second and the total was stored at a memory location representing the
particular level of interest. A total of fifty different levels were examined and totaled.
At the end of one hour, the total in each level was multiplied by the sound intensity
corresponding to that level and all these products were added together. This total
was then divided by the total number of counts (nominally 36,000) and the logarithm
of the resulting number was multipled by 10 to give the HNL. In algebraic form, the
HNL is given as:

HNL = 10 Log 10 4 Ni

N. = Number of counts at the ith level

SPLi = Sound pressure level of ith level
IENi , dB re 20 µN/m2
Thus, the HNL is a measure of the average noise level over one hour, which will .
produce the some noise energy as the actual environment.
The HNL measurements of Table I form the basis for the map contours of Figure 1. Traffic
data for the highways under study does not give annual totals nor does it give daily or
seasonal variations for the total highway system. Therefore, the annual CNEL cannot be
derived from HNL measurements. A few daily CNEL ,estimates were made from sampled
data: These measurements, described in a later section, were insufficient for defining
detailed CNEL contours for current conditions. Hourly estimates of traffic noise
(i.e., HNL), coupled with daily average traffic counts, will enable computation of
CNEL data from Equation 2 in the appendix.

The total number of buses and motorcycles compared with the numbers of cars and trucks
is quite small even on the main arterial so that they do not constitute a significant
contribution to the total noise environment. of the trucks counted, most of these are
of the pickup variety of less than 1-1/2 tons so that the noise attributable to an average
truck could not be placed at more than twice that attributable to an average car. Thus,
the data of Table II was used to obtain Table III wherein the number of cars is added to
two times the number of trucks.

TYPICAL A --WEIGHTED LEVELS
The averaged levels described above do not give information about the peak levels
that may be experienced by a person standing on the curb as traffic passes. Statistical
analysis of the maximum levels may be used to determine those levels that are exceeded
any given percentage of the total time of measurement. Thus, the symbol L10 may be
used to give the level that is exceeded 10 percent of the time. This level has been
found to be representative of the maximum levels that might be measured by a person
holding a sound level meter using the "A" weighted scale with fast meter response.
Table IV lists L10 for each of the sites studied above.

MEASURED COMMUNITY NOISE EXPOSURE LEVEL
A brief program was conducted to show daily variation of the Hourly Noise Levels at
five locations within the City of Newport Beach•. For this study, measurements were
made for approximately five minutes at each of several sites in the City at each of
several different times during one day. The data was recorded and analyzed in five
minute samples in the some manner as was used for the hour long sample studies in pre-
vious sections. Figure 2 illustrates the results of these measurements for the five
locations. It is immediately seen from this data that the daytime levels for the whole
day at every location monitored was between 70 and 80 decibels and each location is
reasonably stable within its own range. It may also be seen that areas where heavy
traffic does not decrease during the evening and nighttime hours, the noise sloes not
drop as it does in the outlying and residential areas. Thus, while the hourly levels at
the comer of Pacific Coast Highway and Dover are never extremely high, the heavy
weighting applied to nighttime noise causes a high daily average or CNEL. Conditions
at Newport Boulevard and Hospital Road, high traffic, many trucks, and all night
operation, combine to produce a very high CNEL at curbside for that location.
SEASONAL VARIATION OF COMMUNITY NOISE EXPOSURE LEVEL
The seasonal variation of the CNEL cannot be evaluated without extensive measure-
ments of the seasonal variations of the traffic data. It is possible to make good esti-
mates of seasonal variations where estimates of traffic flow may be compared with the
traffic flow tabulated in Table II and by use of the data of Table V taken from Refer-
ence 1.

These data indicate that drastic increases of traffic flow must occur before large
changes can occur in the residual noise levels. Not so obvious is the fact that if all
sources increased by a factor of 2, there would be no 45 decibel contour between
Jamboree Road and Irvine Avenue except as the noise was attenuated by the bluffs.
Isabella Terrace would be exposed to the 59 decibel contour and traffic noise would
be clearly audible above other ambient sounds.
AMBIENT NOISE IN QUIRT AREAS
Three "quiet" locations within the City were chosen for monitoring of ambient noise
levels. These locations were chosen as being deep in residential areas not affected
by traffic on the main aerterials. The three locations chosen were: (1) San Bernardino
at 15th Street, (2) Seaward Road at Isabella Terrace, and (3) Amethyst Avenue along
the south Bayfront walkway. In these areas, one hour measurements were made during
the daytime, evening, and nighttime hours to produce a total of nine hours of data.
This data was analyzed in the some manner as was done for all other data reported
above and the results are tabulated in Table VI.

The area at Isabella Terrace shows a constant sound level throughout the day while the
other areas show the normal nighttime reduction. This is due to large numbers of
crickets and other animal noises throughout the measurement periods.

PROPAGATION OF HIGHWAY NOISE INTO THE COMMUNITY
The decay of traffic noise with distance from the highway has been extensively studied
and reported upon in Reference 1. Figure 3 is taken from that report and shows the
expected attenuation of A -weighted noise levels with distance for sounds propagating
over level ground. This figure shows considerably heavier weighting associated with
diesel trucks than has been used in this report for Newport Beach. This is because of
the small number of such heavy trucks traveling the highways of the City. With the
exception of Newport Boulevard and, to a lesser extent, the Pacific Coast Highway,
heavy diesel trucks are relatively rare in the City, since through traffic of this type
uses the San Diego Freeway. Figure 3 shows a decay of 6 decibels per doubling of
distance for decay of noise sources of this type for the first 500 feet. At greater dis-
tances, excess attenuation due to ground absorption, refraction, air absorption and
other factors causes an increase in the decay rate. It must be noted that the data of
Figure 3 has been extrapolated to very low levels (30 decibels) and that measurements
of actual noise cannot be made at such low levels because other noises in the vicinity
of the microphone mask the traffic noise.
The Single Event Noise Exposure Level (SENEL) can be derived from the data of Figure
3 by use of Equation 4.
where
SENEL = LA(R)+ 10 Log [ V.� dB (4)
LA(R) = A -weighted noise level at the distance R
R = Distance in feet
V = Speed of vehicle in feet/second
Since, for a given vehicular speed, the ratio of R/V doubles every time R doubles,
the second term of Equation 4 increases by 3 decibels with each doubling of distance.

The first term decreases by 6 decibels in this same doubling of distance so that the net
result is a 3 decibel decrease in SENBl. for each doubling of distance. Thus, the total
energy intercepted by a receiver at distance does not decay as rapidly as does the
sound pressure.
Decay measurements were conducted within the City to verify the known data repre-
sented by Figure 3 and to evaluate the effects of perturbations imposed on the sound
path by buildings, hills, and cliffs characteristic to Newport Beach. Measurements of
of real traffic noise are difficult as mentioned above because of local noise sources
masking the street noise. However, one such measurement was made at the corner of
Newport Boulevard and Hospital Road, moving west on Hospital Road. Figure 4 is a
photograph of the area studied and it shows a second branch of Newport Boulevard
approximately 160 feet west of the main highway. The measurements were made by
recording five-minute samples of noise at varying distances from the curb of the main
highway and performing the same 'integration technique to obtain the total energy level
as has been used before. This technique tends to minimize the contributions of local
noise sources so that the traffic noise under study dominates to greater distances. This
data is also imposed upon Figure 3 and shows general agreement with the other data
of that figure except at 160 feet where the secondary road becomes a major source of
interference.
The interference caused by local noise sources necessitated the use of another tech-
nique for studying attenuation of sound from traffic noise. Accordingly, an impulse
noise source was constructed to simulate the traffic noise. This source was designed to
periodically discharge a high voltage capacitor through the voice coil of a standard
horn loudspeaker. The size of the capacitor and voltage applied was adjusted to
produce a pulse having a spectral output which closely approximates the spectrum of
automobile traffic when it is modified by "A" weighting of the sound level meter.
Figure 5 shows a comparison of the one-third octave spectrum of the pulse generated
with the octave spectrum of automobile traffic as modified by A -weighting. Both
spectra have been matched at 1000 Hertz. The actual level radiated by the impulse

generator is considerably higher than the traffic noise with peak levels of 146 decibels
(re: 20 µ2N/In ) four feet from the source. Such levels are sufficiently high so that a
meter designed to respond to impulse noise is fully capable of tracing the signal from
146 to 80 or even 70 decibels. It is thus possible to determine decay rates at many
locations where traffic noise would be lost in the ambient noise. A total of 32 differ-
ent locations within the City were examined by this method to determine decay rates
in the presence of various obstacles. Table VII lists these locations with remarks
concerning them.
The results of the impulse noise tests are illustrated in Figures 6, 7, and 8. The 32
sites have been subjectively divided into three general groups to reflect three differ-
ent types of terrain. Figure 6 includes all sites judged to be flat and straight so that
there was no obstruction of line -of -sight between the source and receiver. Figure 7
groups those sites where the source could not always be seen from the receiver, but
there were no abrupt changes. A gentle hill or curve would be reported in this group.
Figure 8 shows the results of tests which included going around a sharp corner or over
the brow of a sharp embankment or behind a building. Thus, site 19 (Crown Drive at
MacArthur Boulevard) involved an embankment at the road and two wooden fences
quite close to MacArthur so the sound from the generator decreased 60 decibels
between four feet and 100 feet. On the other extreme, it was possible to trace the
signal for 1000 feet north on Marigold Street from the Pacific Coast Highway.
The band average shown in Figure 6 was converted to a, SENEL average by use of
Equation 4 and this was used to plot most of the contours on Figure 1. Where geo-
graphical features such as highway Guts (such as Mac Arthur Boulevard at Port West -
bourne and Newport Boulevard at Hospital Road) dictated that more severe attenuation
was in order, the curves of Figures 7 and 8 were used to modify the contours.
The contours for high levels are seen to be very close to the road. bower level contours
spread. on an antilogarithmic scale as would be expected so that the distance between
45 and 50 dB contours is much greater than the distance between 65 and 70 dB contours.

IThus while the data of Figure 2 show very high levels at curbside, the levels only a few
feet from the roadways becomes quite tolerable so that the contours of the highway .
noise near Isabella Terrace drop to as low as 50 decibels while the animal noises are
slightly higher (Table V).
The noise contours are continued on a theoretical basis down to 45 decibels near
schools and hospitals. These contours are extended well beyond any actual measure-
ment capability, but they represent reasonably good extrapolations of the noise that
might be expected. These theoretical spreading losses have also been modified where
large geographical perturbations exist. The contours near the Corona del Mar High
School are unmodified by geographical considerations until the 45 decibel contour
intersects the backbay bluff and then the curve follows the -bluff line. A similar
situation exists at the Hoag Memorial Hospital where the 60 decibel curve tends to
follow the top edge of the bluff there. Beyond this edge, the contours are seen to show
a rapid reduction in noise level. Thus, the hospital grounds are protected from the
full impact of the heavy traffic on Newport Boulevard. The upper stories of the
hospital are exposed to this noise, however.
Contours between Jamboree Road and MacArthur Boulevard, north of Ford Road, have
been continued down to 55 decibels to illustrate, in a small area, the natural exten-
sion of contours for the entire area. It is also illustrated that there is no point within
this area where the traffic noise drops to as low as 50 decibels. It is probable that
isolated points within the area may be found where traffic noise does become inaudible,
but the general area is all above 50 dB.
HELICOPTER NOISE
Police Helicopter
The Newport Beach Police Department operates a helicopter in the normal course of
police duties over the City. The helicopter patrols a varying route at varying speeds,

U,
with occasional high speed runs for emergency work. For this reason, it is not possible
to determine accurate duration weighted sound pressure levels over any given area of
the City. Table ViII tabulates data taken by the Newport Beach Police Department at
several different locations in the City and at several different altitudes. This parti-
cular helicopter has been treated for reduced noise emission so that the levels measured
are considerably lower than those reported in Figure 3 for average unmuffled light
hel icopters.

Type 1561A Precision Sound Level Meter using the A -weighting scale.
City of Newport Beach
The data of Table VIII shows a consistent rol [-off with distance . For example, if
the helicopter passed over a given point at a height of 800 feet at a speed of
60 miles per hour once per hour, it would produce a SENEL of 80.5 or an HNL of 45
dB. If more flights were made, the HNL would increase by 3 decibels each time the
number of flights was doubled. Such a flight during nighttime hours would carry a
10 decibel penalty bringing the line directly below the flight path to an HNL of 55
dB. This is. comparable with the ambient levels found in many areas of the City. A
point one-half mile from the flight path would experience a weighted HNL of 50 dB
and a SENEL of 75 dB. This is comparable with that of an automobile passing once
each hour.
Military Helicopter
An attempt was made to determine the effects of military helicopters flying over the
City. Contact was made with the military authorities with the intention that several
military helicopters would fly over a specified location within the City in a specified
time period. A monitoring station was set up under the planned flight path at the
northwest comer of Big Canyon Reservoir. During the appointed two-hour period, a
single military helicopter flew within range of the microphone, but on a path that
was several hundred yards to the east of the monitoring point. Distance and speed
could not be estimated. This one recording showed a peak level of 78 decibels and a
duration of 13 seconds (at the 10 dB down points) for a SENEL of approximately 86
decibels. One flight per hoar would contribute 51 decibels to the local HNL. This
would not be a large contribution to the HNL of even the quieter areas of the City
(Table VI), but 10 flights in one hour would contribute a great deal. If these flights
occurred at nighttime, they would be cause for great concern.
METHODS AND EFFECTS OF NOISE REDUCTION
1. Barriers
It has been seen during this program that the consideration of barriers as a
method of reducing the intrusion of highway noise into residential areas can be
1 City of Ne27
wport Beach
1
of some use. At points where highways go through narrow deep cuts, the con-
tours of Figure I are sharply compressed, and this has been particularly true
around the Hoag Memorial Hospital. Reference 2 has investigated barriers to
traffic noise and has shown that considerable reductions may be gained through
the use of such barriers. However, the actual reductions obtained were any-
where from 6 to 10 decibels less than those which might be expected from theo-
retical considerations. This is because of scattering of sound by wind turbulence
and other atmospheric conditions which affect sound propagation. Again,
barriers comparable in size with the embankments described would have con-
siderable effect, but, unfortunately would be quite unsightly and prohibitively
expensive. Some rock wal Is have been placed. along residential areas on
Jamboree Road and other places where such areas are exposed directly to traffic
noise, and these are undoubtedly having a good effect.
2. Vehicular Control
The problems presented by roads such as Irvine Avenue, where high speed
traffic is passing directly through residential areas, do not lend themselves
to the use of barriers. For areas such as Irvine Avenue, it is recommended that
the noise sources be more effectively controlled. This might be accomplished
by stringent enforcement of existing speed limits or even through reduction,of
these limits, but the correction factors listed in Table III do not indicate that
large reductions of noise can be accomplished through reduced speeds. It is
suggested, though, that strict enforcement of speed laws, combined with close
supervision of sound control devices on the individual vehicles, would reduce
the noise significantly. it was noted during the gathering of noise data within
the City that large numbers of vehicles have modified exhaust systems which
radiate noise levels in excess of 90 dB(A) and sometimes even 100 dB(A) at
curbside. Conversations with homeowners who volunteered information at the
time of data gathering indicate that these people are more sensitive to the high
1
City of Newport'Beach
1
peaks than their time duration would indicate. Even the levels that are exceeded
' 10 percent of the time (I. ]Q, Fable IV) are excessive, but the 1 percent levels
represent, to the homeowners, noise generated by persons who have I ittle or
' no regard for the environment. Many of these high peaks are the result of the
modification of exhaust systems in an effort to squeeze the last bit of power
from small engines. Such vehicles attract attention. A primary recommendation
for reduction of present noise level would be more strict control of the small
' minority of vehicles generating the highest noise levels. Heavy diesel trucks
might well be restricted from Irvine Avenue to reduce peak levels even though
average levels would be little affected.
' 3. Zoning Changes
Most construction along the heaviest traveled streets, such as the Pacific Coast
Highway, is commercial. Residences behind this commercial construction are
therefore protected from the higher noise levels of these streets. However, it
' would be considered a drastic step to encourage commercialism along these
streets and it is not compatible with overall land use plans. A more practical
' zoning approach to transportation noise reduction is possible by requiring
sufficient noise reduction in external wall construction of single and multi -family
dwellings Facing on busy highways.

APPENDIX A
DERIVATION OF THE HOURLY NOISE LEVEL PER AUTOMOBILE
Table III of the report does not clearly indicate the process used for progressing from
the HNL data measured to the levels that may be expected to be generated by a single
automobile passing once in each hour or HNL*. The physical process involved is to
accumulate the total acoustic energy emitted by the cars passing a given point (really
the energy intercepted by a given microphone) and divide the total number by the
number of cars passing the point to normalize the level to that of a single vehicle. It
must be admitted that this average does not represent any of the possible extremes,
but it has been found to be useful.
When a number is given as a "level," it has been converted to a decibel scale. That
is, the figure given is equal to ten times the logarithm of the total energy involved.
Thus, a Sound Pressure Level or an Hourly Noise Level has been "logged." A quick
review of logarithms will reveal that if a level is divided by a number of events, the
nth root of the total energy will result, rather than a simple factor. It is necessary,
therefore, either to convert the level back into a number, or convert the number of
events into a level. If we have a traffic count of 1000 cars, then we may say that we
have a traffic level of ten times the logarithm of 1000 or TL = 10 Log TC = 30 dB
(spoken as traffic level equals 10 Log traffic count). Given the traffic level, then,
it may be simply subtracted from the sound level to obtain the level that would result
from a single automobile.
It can be shown that a heavy diesel truck traveling at freeway speeds will generate
almost ten times the acoustic energy that an automobile will generate under similar
conditions. However, for traffic conditions existing in Newport Beach, most trucks
are small and speeds are low. For these reasons, an arbitrary factor of two is used to
relate the noise of a truck to that of a standard automobile. That is, one truck equals
two cars. At this point, it is possible to obtain a traffic count consisting of the number
of cars plus two times the number of trucks, take the logarithm of it, and multiply by
ten. An equation may be written to describe this action:
0•

City of Newport Beach
where
HNL* = HNL - 10 Log (Nc + 2Nt) + C]
HNL* = Normalized HNL corrected for the number of events
Nc = Number of automobiles passing a given point
Nt = Number of trucks passing a given point
C] = Constant chosen to normalize road conditions (see Table A-]
and notes)
Table A-] is an expansion of Table III, listing the HNL, 10 Log (Nc + 2Nt), the
corrections (CI) applied, and the final HNL* obtained. The correction factor (CI)
would be zero if all the sites were similar; however, some of the sites involved stop
signs, hills, high speed, and other conditions that would dictate change. Thus, a set
of correction factors was derived to increase the average if it represented cars
operating at less than normal speeds on level ground, or to decrease the average if it
represented cars operating at high speeds, climbing grades, or otherwise generating
more than normal noise.
These correction terms are listed in the notes of Table A-1 and are applied as Column
5 of Table A-1 to the averages of Column 4, giving Column 6. A simple average of
the numbers obtained in Column 6 gives the final value of 40.7 or approximately 41
decibels representing the HNL* that would result from passage of a single car in the
one hour under standard conditions. Under the assumptions of this derivation, one
truck passing each two hours would give the same average level.
The data of Table A-] may be used in reverse to obtain the HNL for any given hour of
traffic count. It may be used in either of two different ways. It is possible to use the
location data of Column 4, Table A-1, to determine the HNL*. This column would be
used where a location listed corresponded closely to the location under investigation.

Then, using information from Column 4, an HNL* would then be added to 10 times the
logarithm of the number of cars (and trucks, if applicable) to obtain the expected
Hourly Noise Level for that location at the time of the traffic count. The CNEL or
daily noise level may then be obtained by determining the hourly traffic counts and
HNL's for the entire day,, using the proper weighting constants for HNL's obtained
during evening and night hours. The 24-hour total of HNL data is added in accordance
with Equation 2.
CNEL = 10 Log 7 Log-1 H-1N�LLD- + 3 F Log-1 H— LE+ 10 FLog-1 HHNLN (2)
where
HNLD = HNL during daytime hours (0700-1900)
HNLE = HNL during evening hours (1900-2200)
HNLN = HNL during nighttime hours (2200-0700)
Annual CNEL data would, of course, be based upon annual traffic counts and would
consist of adding all daily CNEL's together and subtracting 25.6 (10 Log 365). The
second method would be to use the average number of 40.7 as the HNL* and add the
correction factors of Column 5 (using the opposite algebraic sign) that apply to the
area under study and add 10 times the logarithm of the traffic count.
If Hourly Noise Levels are not desired, it is only necessary to determine the total
traffic counts for the daytime hours. (0700-1900), the evening hours (1900-2200), and
the nighttime hours (2200-0700). These counts may then be multiplied by one, three,
and ten respectively and then added together to obtain the total weighted count. This
total may then be operated upon to obtain 10 times the logarithm and this added to the
HNL*. This result must then have 13.8 decibels (10 Log 24) subtracted to give the
CNEL for the day. This operation is detailed in Equation 3.

C NEL = H NL* + 10 Log [Nd + 3 Ne + 10 Nn] - 13.8 + Corrections
Nd = Number of cars + 2 times number of trucks during day

N = Number of cars + 2 times number of trucks during night

(3)
It must be noted that the levels of Columns 4 and 6 of Table A-1, and especially their
averages, do not show great variability from point to point, with or without correc-
tions. Thus, for first order approximations of the traffic noise represented by these
measurements, an HNL* may be taken around 41 decibels at curbside. Even truck
counts may be included as cars if the total number of axles is divided by two to obtain
traffic count. This is considered possible because of the small truck mix obtained.
if trucks become a large percentage of total traffic, they would, of course, have to be
figured separately.
The use of the foregoing data will serve to estimate hourly, daily, and annual noise
levels at curbside along the main streets of Newport Beach through the use of supple-
mentary traffic data.

Gentlemen:
R/35018/RN
Wyle Laboratories is pleased to submit the enclosed proposal, "Studies Leading to
the Noise Element of the City of Newport Beach General Plan," as requested in
your letter of April 13, 1972. The proposal outlines our planned approach to all
three phases of the project. A firm fixed price has been established for Phase I;
pricing for Phases II and III is budgetary only, and will be firmed up as the project
progresses and firm schedule information becomes available.
Pricing for each phase follows:
Phase I — Noise Study of Traffic on Existing Highways $13,600.00
Phase II — Noise Study of Projected Traffic on Existing $4,000.00 to $6,000.00
and Proposed Highways
Phase III — Development of City Noise Ordinance $2,000.00 to $3,500.00
The proposed work wil I be completed within your scheduled dates.
The proposal defines a comprehensive study of the noise environment associated with
the Newport Beach highway and freeway systems. It is intended to be completely
responsive to the requirements set forth in your request letter. However, we are also
prepared to submit an alternate proposal outlining a reduced level of effort directed
solely toward satisfying the basic elements of Senate Bill 691. This reduced level of
effort would, of course, result in a lower price for the subject program.

INTRODUCTION
Wyle Laboratories is pleased to provide the City of Newport Beach with a proposal to
perform studies relating to the noise element defined in Senate Bill 691 and the develop-
ment of a city noise ordinance. The proposed work would be performed by the Wyle
' -Laboratories Cal ifornia,Research Staff.
1 We believe our qualifications in the area of community noise measurement, measure--
•ment of transportation -noise sources and -experience with the development of noise
' -ordinances ,constitute the necessary credentials for the performance of the subject
program. These qualifications include:
• Consultants to the California Department of Aeronautics for the development of
the Noise Standards for California Airports (Assembly Bill 645) and the associated
rtechnical backup.
s A community noise study -for the Environmental Protection Agency addressed to
' that overall portion associated with outdoor noise in the community. This -study
' -involved the analysis of data taken on •a continuous 24-hour basis from 18•com-
munity locations — two of those were in Newport Beach, Site descriptions and
noise data on these two locations are included .in the ,Related Experience Section
-of this proposal.
1 • Consultants in the preparation of a comprehensive noise ordinance for the City of
Torrance. 'Wyle subsequently•delivered a training program to -city personnel rela-
five to the noise ordinance and the development of an enforcement manual.
The following paragraphs contain a restatement of -the program requirements in accord-
ance with the communication received from the City of Newport Beach on April 13,
and a subsequent meeting with city personnel on April 14, 1972. This section is fol-
lowed by a Program Plan which sets forth Wyle's proposed method for satisfying the
Iprogram requirements.

' Phase I-- Noise Study of Traffic on Existing Highways— Completiony by August 1, 1972
This phase will involve 'three tasks. The first task will be to determine and map noise
' contours according to the guidelines contained in Senate Bill 691 for al existing major
highways. Noise associated with the operation of* Orange County Airport is not rele-
vant to this program. The major highways of interest to the City of Newport Beach
are indicated on Figure 1.
The referenced Senate bill requires that noise contours be expressed in an acoustical
standard based on A -weighted sound level measurements and that these measurements
contain corrections for the duration of individual single events and the total number
of events in a.24-hour period. It -is evident that the Community Noise Equivalent Level
' rating scale (CNEL) would best satisfy this requirement. This rating scale was developed
by Wyle Laboratories for the Department of Aeronautics.
The second task wi I I be to determine ambient noise levels in various areas in the com-
munity for different types of land uses. A final task will be to make recommendations
I on how to minimize the noise impact of,highways on various land uses within the City
' of Newport Beach.
Phase 11— Noise Study of Projected Traffic on Existing and Proposed Highways — To
l
Be Accomplished Between January 1, 1973 -and March 1, 1.973 �
This phase will be to "determine and map the noise -contours for projected levels of
traffic on all existing and proposed highways -and freeways. Conclusions regarding
' appropriate site or route selection alternatives or noise impact upon land uses shal I be
,made for inclusion into the General Plan ".
It is desirable to organize .the data for Phase .I and II into a format that would permit
a computer file to be established for all relevant highway noise data for Newport
' Beach. This file could be updated on a regular basis to reflect changes and additions
to the transportation system.
City of Newport Beach
Phase III— Development of City Noise Ordinance — (Exact Schedule Not Specified)
t
As a final phase, a noise ordinance wi I I be developed for ultimate adoption as a part
V.
' of the Municipal Code. This ordinance would reflect relevant elements of other city
noise ordinances — such as the California League of Quiet Cities Model Noise
' Ordinance. It would also reflect the results of the investigation of Phase I and II.

PROGRAM PLAN - PHASE ONE
Our approach to Phase r will be to develop annual CNEL contours based on field
measurements and analytical statues of the Newport Beach highway network. One
result of these studies will be a computer file containing the noise profiles at a series
of representative highway locations. These profiles wi I I be a basis for developing
CNEL contours for the highway ne#work and the adjacent property. The noise contours
will be contained in a report summarizing supporting data and providing recommenda-
tions for a noise reduction program.
The following specific steps will be involved in implementing Phase I:
Site Inspection
Azonsultant and an engineering aide will drive over the complete highway network
depicted in Figure I to determine the general characteristics of the Newport Beach
highways, and the associated residential and commercial properties. Appro�cimately
30 highway sites, typical of the local land use categories and sideline property char-
acteristics, will be selected during this examination. A detailed description of each
of these sites will be compiled. Typical data obtained will be:
,Nature of highway -single -lane, double --lane, four -lane, grade, etc.
• Traffic flow characteristics -this includes factors which govern the basic speed
-cif traffic on this artery such as frequency of stop signs, placement of signals,
seed regulations and other factors -- in addition to traffic flow -- which would
influence vehicle speed and hence noise exposure.
• Sideline property characteristics-- this would include the elevation of sideline
property, i.e.. road level above, below or on a level with nearby property,
characteristics and density of building construction on sideline Property and
changes in sideline property characteristics at increasing distances back from
highways.
City of Newport Beach
' These descriptions of representative sites will be analyzed to select a number of field
stations. A highway field station is defined as a site where physical measurements of
' noise levels, traffic flow and traffic mix will be made by Wyle personnel. The field
stations will be representative of the range of highway, sideline property and land use
conditions found in Newport Beach.
In addition to the highway field stations selected, we will select a representative set
of community field stations. A community field station is defined as a site where
measurements of ambient community noise levels will be made. The community field
' stations will be representative of the range of land use conditions in Newport Beach.
' Measurement and Analysis
Noise measurement at the highway field stations will be made to obtain input data for
' the Wyle Highway CNEL Computer Program. This program calculates the CNEL at
sideline distances from highways based on traffic flow and vehicle characteristics. It
' contains correction factors to account for the effect of highway grade, sideline terrain,
shielding and start/stop variations in vehicle noise. Data defining these correction
factors will be obtained through a series of measurements at the highway field stations.
Based -on existing data of the daily and seasonal changes in traffic flow and mix in the
Newport Beach area, and the data measured at the highway field stations, the com-
puter program will provide annual and seasonal CNEL levels. The format of the
' processed data will be a series of sideline noise profiles showing the variation in CNEL
with distance from the highway at representative stations. A sufficient number of pro-
files will be developed for each field station to establish CNEL levels for the existing
and projected range of traffic flow and mix conditions. The data gathered from the
highway field measurement stations can, of course, also be used to calculate CNEL
levels at other highway locations having similar characteristics. This procedure,
1 together with interpolation between highway locations, will allow contours to be con-
structed joining points of equal CNEL along the major highways.

•
A sufficient number of ambient noise level measurements at each of the community
noise field stations will be taken to accurately define the central tendency of•these
levels. The ambient noise levels at these stations wil I be sampled over a 24-hour
,period, the number and the frequency of the samples depending upon the variation
in the measurement levels. In thismanner, the variation of ambient noise in both
space and time can be determined for each of the -land-use categories.
.Report
At the conclusion of the measurement and analysis tasks, the Phase One report will be
finalized. This report will contbin the -Following data:

local correction factors characterizing -the highway.
The report will also summarize a general step-by-step noise reduction program encom-
passing the definition, monitoring, and eventual alleviation of transportation noise
in the Newport Beach area.
PHASE TWO
The Phase II calculations will'be made utilizing the data base of sideline noise profiles
established for Phase I and the development of projected noise profiles for field stations
representative of highways and sideline property characteristics for projected highway

expansions and new freeways, The "computerized Newport Beach Highway/Community
Noise Pile" will constitute a model which may be manipulated by inputting changes in
traffic mix and now sideline terrain property characteristics to obtain projected CNEL
(and noise) levels.
The technique proposed for these calculations will greatly simplify the task of project-
ing noise contours for the new freeways and highways. In other words, this wi II provide
.a practical tool for optimizing alternate plans for the expansion of the Newport Beach
transportation system.
The report submitted at the end of Phase Two will contain:
s A matrix presentation showing noise reduction to be achieved in various land
-use areas associated with potential alternate traffic and highway conditions.
A -series of recommendations relating to proposed highways and traffic conditions
which would optimize reduction of the Newport Beach noise environment.

-traffic on existing and proposed highways and freeways.
e Recommendations relating to zoning, types of building construction, and technique
for shielding recreational facilities which would reduce the noise input on Newport
Beach residents.
PHASE THREE
The municipal noise ordinance for Newport Beach --- if properly drafted and adequately
enforced —can be a key element in controlling and reducing the amount of noise which
reaches the inhabitants of the city. It must be a working document and, as such, should
be written to provide the maximum feasible amount of noise protection at the least pos-
sible enforcement cost. The noise ordinance should:
s Treat all the types of noise sources within the city`s jurisdiction (a city cannot
directly control overflying aircraft; direct control of motor vehicle noise has been
preempted by the state).

• Provide protection to'all portions of the city, but in differing degrees according to
the relative need for quiet connected with various uses of land and according to
the achievable limits as related to the current background noise levels in the
various regions.
• Provide particular protection for residential areas, and increased protection at
night in those areas.
• Place more stringent limits upon long-lasting noise than on noise of brief duration.
• Place more stringent limits on noise of extraordinarily irritating quality (such as
,noise containing a whine or pure tone, or noise which is,a repetitive hammering).
0 Be based upon a simple, reliable acoustic scale which will result in the simplest
possible enforcement (measurement) procedures and the least expensive measuring
equipment consistent with necessary standards of accuracy.
• Be numerically specific,' to serve as a guide for new industry and new develop-
ments, making clear the noise limits which must be met if they wish to locate in
the city.
• -Be in a form which lends itself to integration with other elements the city may
later adopt as part of a comprehensive noise control program.
• Be unmistakably clear, legally fair and technically feasible.
Wyle proposes to develop an ordinance meeting these criteria for the City of Newport
Beach which also reflects consideration of data developed in the Phase I and Phase II
programs. The tasks associated with the development of this ordinance are:
3. review of all background data on Newport Beach noise problems —sources, time
of occurrence, duration, levels, complaint history.
2. Consider the legal limits of control which the city of Newport Beach may
exercise over noise sources.

3. Develop specific criteria and objectives for the Newport Beach ordinance.
4. Review relevant city, noise ordinances — i.e., the California league of Cities
Model Noise Ordinance— for application to the Newport Beach ordinance.
5. Draft of preliminary noise ordinance by Wyle for review by Newport Beach.
6. •Review of draft ordinance and incorporation of appropriate supporting text by

WYLE LABORATORIES RESEARCH STAFF - A SYNOPSIS
Wyle Laboratories was established in 1949 to provide environmental testing services
to industry and government, utilizing its capabilities for testing in all the natural
environments such as wind, rain and temperature, and in the vehicle -related environ-
ments such as vibration, shock and noise. Throughout the years, Wyle has grown to
' provide a wide spectrum of technical services including testing, engineering and
research in various environments. In addition, Wyle has diversified into other fields
and has grown to a level of gross sales of approximately $100,000,000 per year.
' Wyle Laboratories' Research Staff was established in 1963 in Huntsville, Alabama,
with an initial objective of supporting the NASA space effort. From the beginning,
' the principal emphasis in the Research Staff has been acoustics and dynamics, supple-
mented with a variety of related disciplines including physics, aerodynamics, fluid
dynamics, electronics, systems engineering, mathematics and computer software.
' The staff has the support of Wyle's extensive environmental testing facilities and
instrumentation for both laboratory experiments and field measurements. This sup-
porting experimental capability gives the staff a unique flexibility in approaching a
research project with an optimum balance between experiment and analysis.
' Since 1963, the staff has grown significantly, and today there are three (3) major
centers of research and engineering skills within the company. These are located at
El Segundo, California (Wyle Headquarters); Huntsville, Alabama; and Hampton,
Virginia. Accompanying this growth, there has been a continuous diversification in
the clients served by Wyle and in the types of problems which have been solved.
Wyle serves many agencies of the government including four (4) NASA centers; the
Federal Aviation Administration; Department of Transportation; Department of Housing
and Urban Development; United States Air Force, Army and Navy; Federal Railroad
Administration and many others. Typical research problems undertaken include the
following:
I
• Investigating basic mechanisms of noise sources such as jets, compressors and heli-
copter rotors with theoretical models and experimental validation.
• Determining human subjective response to noise, determined by extensive psycho -
acoustic experiments.
• Examining structural dynamic response to noise, blast and earthquakes, including
development of methods for prediction of vibration response of both buildings and
vehicles.

' • Developing advanced experimental facilities such as an acoustic chamber large
enough to take a major section of the Apollo vehicle, and a facility which will
1 subject a railroad car to all of the dynamic forces it will experience when
traveling 300 miles per hour over the track.
'
• Developing structures for better noise control such as high -transmission -loss, low-
cost wall systems.
• Investigating the mechanisms affecting propagation of noise through the atmosphere,
developing more accurate and practical prediction techniques.
'
• Developing advanced computer -based instrumentation systems and software for on-
line real-time measurement and control of noise, vibration and other physical
'
phenomena.
• Determiningthe properties of pressure fluctuation ;Fields resulting from turbulence

and other unsteady aerodynamic flows through combined theoretical and experi-
mental studies.
• Development of new methods for simulation or testing to seismic and blast loads.
' W le Laboratories' Research Staff is also engaged in numerous consulting projects for
y
state and local government agencies, industry, architects, planners and others.
' Through these activities, Wyle has become heavily involved in:
• Establishing criteria for environmental noise.
' is s and regulations for both
• Development of noise code eg airports and cities.
' • Inclusion of noise considerations in urban planning.
• Soundproofing of homes, schools and industrial buildings.
• Architectural acoustics design of buildings for various uses.
' • Measurements of aircraft and city noise.
' • Development of new concepts of systems for monitoring the noise environment.
• Development of practical devices and design for the reduction of noise at the
' source.
• Measurement and control of industrial noise.

TYPICAL LARGE-SCALE PROGRAMS
' • Noise Standards for California Airports. Wyle served as acoustical consultant
to the California Department of Aeronautics in development of the first state-
wide airport noise regulations in the nation, adopted November 10, I970,
for all existing and future airports in the state requiring a state permit. Pro-
gram has involved a close working relationship with the Department of Aero-
nautics, their advisory committee, their legal counsel plus interactions and
explanatory meetings with the public and various affected groups, to provide
an innovative and integrated acoustical -legal document responsive to the
' problem of controlling airport noise by regulation at the state level.
• Community Review Program for City of Inglewood (California) under their
' HUD grant. Wyle served as acoustical consultant to Urban Design
Collaborative, to provide the acoustical advisement required for long-range
planning of a city which lies under the approach path of a major metropolitan
' airport and which has the traffic noise and other problems typical of most
urban areas. Program involves working with an interdisciplinary consulting
team and the city's staff, to develop performance criteria for noise limitation,
' land use plans, building code amendments, ordinances and other planning/
legal/political tools for reducing the noise exposure of the citizens.
'
• Environmental Impact Study on Potential Commercial Use of Oxnard Air
Force Base, Ventura Coun , California. Wyle served as acoustical consultant
to Adrian Wilson Associates, airport planners, to predict the potential noise
' environments associated with various postulated uses of the air base as a civilian
airport, to recommend numerical aircraft noise/land'use compatibility guide-
lines and apply them to an assessment of the compatibility of the proposed airport
'
with existing land uses, and to recommend specific operational restrictions on
the airport and legal means for their enforcement, together with compatible
land use development guidelines. The program involved extensive coordination
with affected communities and numerous public presentations in a controversial
atmosphere.
'
• Phase II Master Plan for Air Transportation for the Count of Orange (California).
Wye served as acoustical consultant to the Ralph M. Parsons Company in a
planning program to assess alternative means for meeting the air transportation
ineeds
of Orange County, working within a set of environmental quality guide-
lines for noise limitation, and internalizing the costs of noise abatement measures.
The program required the establishment of noise limits, numerous predictions of
'
airport noise environments (using Wyle's airport noise prediction computer program
and data bank), and close coordination with the client in evaluation and public
'
presentations of the findings.

' STUDY ON THE EFFECTS OF NOISE POLLUTION
Two studies on the effects of noise pollution were undertaken in this program. These studies
' were part of a major program by the Office of Noise Abatement and Control of the
Environmental Protection Agency and are summarized in the recent EPA Report to Congress.
' The first study related to "Noise From Transportation Systems and Small internal Combustion
Engines." It involved an in-depth evaluation of the noise characteristics of commercial
aircraft, V/STOL aircraft, general aviation aircraft, highway vehicles, rail systems, ships,
recreation vehicles, small generators, lawn care equipment and other devices powered by
' small internal combustion engines.
In pursuing this study, Wyle first made a survey of the manufacturers of these sources to
' determine the status of all current and projected noise abatement programs., In parallel
with this survey, a literature search —supplemented by a noise measurement program —
' was conducted to establish the noise levels generated by these devices for both the operator
and an observer. In addition to these studies, the actual noise generating mechanisms of
each source was studied in order to properly evaluate the various noise abatement techniques.
' .The results of this study were summarized in a report which considered:
• Nature and economic significance of the industry associated with the source.
' • Basic noise characteristics of each type of source.
• Environmental noise attributes of each source.
' • Past and present industry efforts toward noise reduction.
• Estimated potential noise reduction for the future with today's technology.
' The second study addressed that part of the overall pollution problem which is associated
with outdoor noise in the community. The basis for the community noise study was a survey
of IS different community sites -- divided into categories ranging from a noisy downtown
environment to a quiet countryside environment. Continuous 24-hour noise level recordings
were made at each of these locations. An extensive computer analysis of these data were
' subsequently performed to provide a detailed statistical analysis over a 24-hour period for
each site. The result of this study was a comprehensive report developing a preliminary
baseline for today's noise environment in a typical range of communities. Specific topics
presented in this report included:
• The variation of noise at a single location throughout a 24-hour day.
• A comparison or test of the various community noise measurement scales.
r The nature of constant and intermittent sounds and the constraints these sounds
place on speech and other human activities.

Description: Major recrea-
tion beach state park; arge parking
area but no major high speed arterials
or streets nearby. 0.5 mile to Pacific
Coast Highway; channel entrance to a
very large recreational boating and
bay area. The beach and parking
area is about 0.2 mile wide and
located at base of a 75-foot bluff.
Noise Environment: Major intruding
events were due to a variety of air
vehicles; several helicopters and small
propeller aircraft at close range, and commercial sets at greater distances. Con-
siderable noise during the day came from recreational activity on the beach and in
the refreshment stand area. The residual noise during the evening was dominated by
the surf which varied from 50 to 64 dB(A) with the breaking of the waves. During
the day the recreational activity raised the residual level to the 56 to 5$ dB(A)
range and no surf noise pattern is noticeable on the record. An unusual intruding
event was the beach sand cleaner at 7:30 a.m. The microphone was located about
100 yards from the surf at the junction of the sand and parking lot. It was placed
20 feet above ground level and above a partially covered breezeway about 75 feet
from the refreshment stand.

Noise Environment: Major intruding noise sources were created by commercial jet
aircraft in their climbout pattern, a few helicopter events, propeller airplanes and
some automobile noise. Other intruding events results from dogs barking, lawn
mowers, hammering, a car revving up across the street, a garbage can rolling down
a driveway, and jet engine thrust reversals at the airport. The residual noise levels
were relatively low and seemed uninfluenced by the presence of crickets at this
location. Cricket activity is noticeable on the 24-hour record during the 0100 hour
when one or more crickets were relatively close to the microphone. The residual
noise levels were apparently dominated by neighborhood activity and distant traffic.
The microphone was located 45 feet from the curb and 20 feet above ground level.

COMPREHENSIVE OUTDOOR NOISE ORDINANCE & TRAINING PROGRAM
' FOR THE CITY OF TORRANCE
The Wyle laboratories Research Staff served as acoustical consultants to The City of
Torrance in the preparation of a comprehensive noise ordinance tailored to the city's
needs.
Wyle first performed a limited noise measurement survey to determine the spatial and
temporal distribution of background noise levels in the city and the nature of specific
noise problems. A draft originated by the city's staff was then expanded and made
uantitative so that the resulting ordinance covers al I kinds of noise sources within
the legal domain of cities, and applied quantitative noise limits tailored to specific
regions and land uses within the city.
1
An accompanying final report was prepared, presenting the underlying rationale, sum-
marizing the results of the noise survey, and placing the recommended ordinance in
perspective with other recommended actions to achieve a quieter city.
The ordinance was adopted by the City Council, becoming effective in May, 1971.
Wyle is continuing to assist the city in other elements of its noise control program,
including the training of enforcement personnel.
In early 1972, Wyle prepared and presented a Noise Ordinance Training Program to
indoctrinate Torrance City personnel in technical and practical aspects of noise. This
program consisted of the following tasks:
0 Introduction to noise ordinance
• Basic coverage of measurement terminology and techniques
• Maintenance and calibration of sound level meters
• Develop a 'Standard Operating Enforcement Manual" (in process)

planning and architectural firms, an economics research firm, and a social science
research firm. The major problems in Inglewood include an old central business
district in which most of the buildings fail to meet earthquake codes, and a noise
problem resulting from the fact that Inglewood lies under the aircraft approach paths
'
to Los Angeles International Airport. Therefore, the subcontracted consultants
include specialists in acoustics, building structures, law, and preventive psychiatry.
During this one-year study, Wyle Laboratories established environmental quality
criteria for noise, provided the other members of the team with inputs to assess the
I
resources needed to achieve the desired environment, and recommended specific
physical and legal steps the City could take (within the available resources) toward
achieving the environmental goal.

AIR TRANSPORTATION MASTER PLAN (PHASE II)
FOR ORANGE COUNTY
Wyle Laboratories served as acoustical consultant to The Ralph M. Parsons Company in
an air transportation master planning effort for Orange County. In this six-month pro-
gram, the objective was to provide the County with a definitive plan for a system of
airports which would provide the necessary level of air service to the citizens of
Orange County while minimizing the environmental noise impact to existing communi-
ties.
Wyle Laboratories utilized their computer program to predict airport noise environments
associated with various proposed operational modes for each airport. Airports involved
in the study included the existing Orange County Airport, three potential new airports
(one general aviation, one metroport, and one recreational airport) and three military
air fields with possibilities of joint civilian use.
Based on Wyle's recommendations on noise limit criteria for various land uses, the
various sites were evaluated, recommendations made as to their relative suitability,
and the potential costs of land use conversions and.building modifications iaternali,zed
as a cost to the aviation activity. Site selections, limitations of service, noise abate-
ment measures and noise monitoring systems were affected by the acoustical consultant's
recommendations.

HOME SOUNDPROOFING PILOT PROJECT
The Los Angeles Department of Airports, deluged by homeownercomplaints and law-
suits due to community noise problems from aircraft operations at Los Angeles Inter-
national Airport, funded a pilot project involving the soundproofing of twenty existing
homes against aircraft noise. The purpose of the project was to determine whether the
soundproofing of large groups of homes would be suitable as one portion of an overall
system solution, in terms of homeowner satisfaction and cost.
The Home Soundproofing Pilot Project was conducted in several sequential phases. In
Phase I, the design of the entire experiment was laid out in such a way as to obtain a
representative sample of the numerous Southern California house construction types and
of the various geographic, political, and noise exposure regions around the airport.
Phase 11 included all the actual soundproofing experimentation. First, a series of tests
were conducted in three uninhabited houses owned by the City and located roughly
under a takeoff path; these three houses were used as test sites in which to evaluate
whole series of house elements in terms of acoustical performance and actual cost for
materials and installation labor. Using aircraft flyby noise, the acoustical performance
of each test element was evaluated by comparing simultaneously recorded signals from
indoor and outdoor microphones. Modifications to all major exterior elements of houses
were tested: roofs, walls, ceilings, floors, windows, doors and exterior vents -- some
'
sixty modifications in al I -- plus the effects of acoustical reflection and shielding by
patio walls and the house itself. From these results, the most cost-effective modifi-
cations were selected for use in owner occupied homes.
Finally, twenty inhabited homes (volunteered by their owners for the project) were
modified and subjected to acoustical field performance tests. Three different degrees
of soundproofing were utilized, corresponding to reductions in noise level (from an
outdoor microphone to an indoor microphone) of 25, 35 and 45 dBA respectively.
'
Before and after the modifications, the residents of the homes were interviewed using
an extensive questionnaire. This satisfaction assessment revealed that the lowest de- ,
gree of soundproofing was insufficient; that the intermediate degree provided a high
degree of satisfaction in most cases; and that in areas where the highest degree of
soundproofing is warranted, the homeowners tend to judge the region unsuited to resi-
dential use because of the outdoor environment. These results combine to indicate
that the intermediate degree of soundproofing is promising.
The complete experiment description, acoustic performance and cost results, interview
results and details of how to modify, homes against exterior noise are provided in a two -
volume report, copies of which must be obtained from the Department of Airports:

NOISE STANDARDS FOR CALIFORNIA AIRPORTS
By passage of Assembly Bill 645 (1969), the California Legislature mandated the State
Department of Aeronautics to adopt noise standards to govern the operation of aircraft
and aircraft engines at airports operating under a permit from the Department. This
covers all but military airports and some small private airports which do not invite the
general public. The Wyle Laboratories Research Staff served as the acoustical con-
sultant to assist the Department of Aeronautics in drafting the regulations.
A seven -member Advisory Committee on Noise Standards, whose members were
appointed by the Governor in accordance with AB 645, assisted the Department in
selecting an acoustical consultant and in reviewing and recommending modifications
as the consultant's work progressed. In a series of meetings of the Committee, the
Department, the consultant and legal counsel from the Office of the Attorney General,
a proposed noise standard was developed and agreed upon by vote of the Advisory
Committee for purposes of the public hearings. On April 1, 1970, the Department of
Aeronautics provided copies of the proposed noise standard to all members of the Legis-
lature, and thereafter to all persons requesting copies, in a document entitled, "Report
to the Legislature on Proposed Noise Standards for California Airports Pursuant to Pub-
lic Utilities Code Section 21669."
Public hearings on the proposed standard were held in Los Angeles and San Francisco
on May 19 and 20, under the auspices of the California Aeronautics Board. Subsequent
to these hearings, additional working sessions were held with the Department, their
consultants, the Advisory Committee and the Aeronautics Board to revise and improve
the noise standard on the basis of testimony received in the public hearings. On Nov-
ember 10, 1970, the California Aeronautics Board formally adopted the revised noise
standard, and this adopted regulation is scheduled to go into effect December 1, 1971.
The regulation itself is contained in California Public Utilities Code, Section 21669
et seq., Title 4, California Administrative Code, Chapter 9, Subchapter 6, com-
mencing with Paragraph 5000.
There is also available a background information report intended for reference by all
interested parties including the lay public:

Noise Regulations for California Airports," Final Report to the California
Department of Aeronautics, Report No. WCR 70-3(R), January 29, 1971.
This report provides an introduction to the basic concepts involved in solving or pre-
venting a community noise problem, describes the basic physical and human factors
concepts required for quantitative description of a noise environment, presents the
underlying rationale for the structure of the noise regulations, presents the back-
ground data underlying the selection of the numerical limits for cumulative noise
and for single flyby events, describes techniques for controlling and reducing airport
noise, and discusses the noise monitoring systems required for implementation of the
regulations at airports with existing noise problems.

BACKGROUND AND EXPERIENCE IN AIRPORT NOISE ENVIRONMENT PLANNING
A comprehensive and valid definition and analysis of noise impact for any airport requires
the application, in depth, of technical competence in several areas. The extensive back-
ground and experience of Wyle Laboratories in these areas is briefly summarized in the
fol lowing:
0 Planning Methodology
The application or development of innovative planning techniques has been a contin-
uing part of the activity of the Research Staff of Wyle Laboratories as consultants for
government agencies and industrial concerns on acoustic environments. This work
has included the development of long range research plans for evaluation of environ-
ments, the development of new standards for noise monitoring, participation with
A and E firms on complete turnkey programs for planning and construction of environ-
mental test facilities.
• Prediction of Aircraft Noise
Looking to 'the future, substantial changes from current conditions will occur in the
type and mix of the commercial jet aircraft fleet. Therefore, for planning purposes,
it is often necessary to anticipate the noise exposure from new aircraft yet to be
built. Wyle Laboratories is uniquely equipped to provide this capability by virtue
of our nationally recognized position as one of the major contributors to the state- .
of -the -art of aircraft noise prediction. This posture has been achieved through
results from a number of research and consulting studies for various NASA agencies,
the U.S. Air Force and aircraft manufacturers. For example, -we acted as con-
sultants on noise environment for the SST aircraft to the Office of Supersonic
Development, Department of Transportation.
a Airport Noise Monitoring
Installation of portable or fixed noise monitoring systems is now required at some
airports in the State of California as a result of legislative action and is being
utilized elsewhere as a practical tool for the airport manager to effect significant
control of his operations to minimize community noise problems near his airport.
Wyle Laboratories have been involved for many years in 'instrumentation system
design and development and have supported the Los Angeles Department of Airports
in their planning procurement and checkout of a noise monitoring system. This type
of background, coupled with our own extensive field experience in noise measure-
ments, provides a wide range of supporting capability to airports who need to plan
or conduct airport noise measurements.

Prediction of Sound Propagation
Typical weather conditions at any given airport site are not necessarily representa-
tive of average conditions throughout the country. The weather can influence the
sound propagation by changing the atmospheric attenuation for the temperature --
humidity conditions which are characteristic for the airport. Wyle has carried out
original research on the topic of sound propagation losses to advance the basic
state-of-the-art in this area and are continuing this effort under contract to the
Army Research Office, Durham, North Carolina. Accurate assessment of the aver-
age atmospheric propagation loss can, in some cases, significantly reduce'the size
of the noise impact footrpint at an individual airport.
Community Response to Noise
The response of a community near an airport to noise is a composite of many factors,
some of which can be measured or defined in terms of a subjective reaction scale '
and related to an objective measure of the noise. Wyle has been responsible for
several basic studies on subjective and objective reaction of people to noise. These
studies have been carried out under contract to the FAA and NASA and have pro-
vided basic data, previously unavailable, on noise scales for STOI_ and general
aviation aircraft as well as providing additional detailed data on noise scales for
commercial aircraft and community reaction to noise.
Noise Control for Buildings
Planning for noise environments around•a given airport includes consideration of
noise reduction requirements for residences, commercial installations or industrial
buildings so as to minimize internal noise levels from ground and takeoff operations
of jet aircraft. Whatever noise exposure exists can often be attenuated by the
building structure to achieve acceptable internal noise levels. Wyle personnel
have carried out several studies involving noise reduction for residential and
commercial buildings near major airports. We have also conducted studies on
sound transmission loss through building structure under a government contract and,
as consultants, have evaluated sound transmission loss of building components for
a variety of commercial clients. This background will aid in making practical
engineering evaluation of any required noise control for buildings or residences
near airports.
