Sound Data
Model 8.5RES and 12RES 8 point logarithmic average sound
level is 65 dB(A).
For comparison to competitor ratings, the lowest point sound
level is 63 dB(A).*
All sound levels are measured at 7 meters (23 ft.) with no load.
* Lowest of 8 points measured around the generator. Sound levels at
other points around generator may vary depending on installation
parameters.
