Sound Data
Model 10RESV and 12RESV 8 point logarithmic average sound
levels are 67 dB(A) during weekly engine exercise and 71 dB(A)
during full-speed generator diagnostics and normal operation.
The lowest point sound levels are 64 dB(A) and 69 dB(A)
respectively as compared to competitor ratings.*
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.
