Model 30RCL & point logarithmic average sound levels are
54 dB(A) during weekly engine exercise and 61 dB(A) during
fullespeed generator diagnostics and normal operation. For
comparison to competitor ratings, the lowest point sound levels
are 52 dB(A) and 60 dB(A) respectively. *
All sound levels are measured at 7 meters with no load.
