SUBJECT: RESULTS OF ACOUSTICAL CERTIFICATION MEASUREMENT
FOR 1406 WESTCLIFF DRIVE -- CITY OF NEWPORT BEACH
Dear Mr. Wright:
We are pleased to inform you that the pool equipment installation located at 1406
Westcliff Drive in the City of Newport Beach complies with the City's 55 dBA noise limit. No
additional noise mitigation is necessary.
The installation was measured on Monday, December 4, 2023, using a Larson Davis
Model 700 Type 2 Sound Level Meter. The installation was observed to consist of one Pentair
Intelliflo pump, one Pentair Whisperflo pump, and a MasterTemp heater, all located in a side
yard. The measurement microphone was placed just beyond the top of the nearest property line
wall directly opposite the pool equipment. The measurement reported a level of 54 dBA with
both pumps and the heater unit operating simultaneously. This level complies with the City's 55
dBA noise limit.
Thank you, and if there are any questions, please do not hesitate to call.
