Dear Ms. Pomponio:
Tectonic Engineering was asked to provide a noise analysis/comparison letter for the proposed Verizon
Wireless emergency backup power generator that is part of the above referenced project. We obtained
noise specifications from the manufacturer Rehlko for their proposed standard 50kW outdoor diesel
fueled AC generator including a level 2 sound-attenuating enclosure. The average sound pressure level
for the generator is 67.4 dBA at a reference distance of 23.0 feet.
We understand that consistent with normal Verizon Wireless procedure, absent exigent circumstances,
the generator is expected to run once every two weeks during daytime hours for approximately 30
minutes for routine testing purposes.
Sound attenuation for a point source (stationary source) equals a sound level reduction of 6 dBA per
doubling of distance between a noise source and a receptor when there are no obstructions present
between the two elements. Using this information, we can deduce the following noise levels that one
would anticipate when the equipment is in use:
• The distance between the generator and the nearest property line of an adjacent property which
is not associated with the project is approximately 469-feet away, located to the east of the
generator; the anticipated noise level at this point would be approximately 41.8 dBA.
• The distance between the generator and the nearest residence is approximately 627-feet away,
located to the southeast of the generator; the anticipated noise level at this point would be
approximately 39.3 dBA.
For comparison purposes, approximate decibel levels for normal conversation equal 60 dBA, for vehicular
traffic equal 85 dBA, and for a running lawnmower equal 107 dBA. Based on the calculated values for the
equipment, the anticipated noise levels will be lower than that experienced for normal conversation.
