SUBJECT: RESULTS OF ACOUSTICAL CERTIFICATION MEASUREMENT
FOR 17 BOARDWALK -- CITY OF NEWPORT BEACH
Dear Mr. Thomas:
We are pleased to inform you that the pool equipment installation located at 17
Boardwalk 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 Thursday, July 20, 2023, using a Larson Davis Model
700 Type 2 Sound Level Meter. The installation was observed to consist of three Jandy EPump
pumps and a Jandy JXi heater. 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 55 dBA for all three pumps and the heater unit operating simultaneously. This level
meets the City's 55 dBA noise limit.
Thank you, and if there are any questions, please do not hesitate to call.
