What is the decibel rating?

Caterpillar does not publish directly comparable sound data for the RP series, due to lack of industry noise measurement standards. However, these generators have an over sized muffler with sound absorption materials, side panels, and over sized fuel tank above the engine, which serves to contain noise as well.
