Pool and/or Spa Noise report for residence at 2306 Port Aberdeen PI., N. B., CA
At about noon on Tuesday, August 25, 2020 1 measured pool and/or spa equipment noise at
your nearest neighbor's residence to test for compliance with the Newport Beach noise
regulation (10.26.025).
Newport Beach Residential Noise Standard
For Noise Zone 1 (residential) the C.D.M. and N. B. regulation's daytime noise level standard
(maximum noise level from 10 p.m. to 7 a.m.) is 55 dBA— corrected for ambient noise. The
nighttime noise standard (max noise level from 7 a.m. to 10 p.m.) is 50 dBA. The measurement
is corrected for ambient noise and rounded to the nearest decibel as shown below.
I am pleased to report that measured pool and or spa apparatus noise meets the Newport
Beach noise standard for 24-hour use. Pertinent details of my findings are reported below.
Locations and values of daytime noise measurements
Uncorrected pool and or spa noise + ambient noise measured at property line: 50.03 dBA
Ambient noise level measured at this location: 44.23 dBA
Pool and or spa equipment noise corrected for ambient noise:
Pool and or spa equipment noise rounded to the nearest decibel: 48 dBA
48 dBA (Pass for 24-hour use)
The currently installed pool and or spa apparatus noise of 48 dBA meets the Newport Beach
noise code for both "daytime" use (7 a.m. to 10 p.m.) and "nighttime" use (10 p.m. to 7 a.m.),
since the noise corrected for ambient does not exceed 50 dBA.
