Generator Set Sound Data
Model 20RESC 8 point logarithmic average sound levels are
64 dB(A) during weekly engine exercise and 69 dB(A) during
full-speed generator diagnostics and normal operation. For
comparison to competitor ratings, the lowest point sound levels
are 62 dB(A) and 67 dB(A) respectively.*
All sound levels are measured at 7 meters with no load.
* Lowest of 8 points measured around the generator. Sound levels at
other points around generator may vary depending on installation
parameters.
