Give a listen! Independent sound tests comparing generator noise output now available online.

The noise levels of four brands of residential generators were compared in a series of carefully measured evaluations by SGS Testing. The RS20A generator from Cumins Onan proved the quietest of all the models tested, at every load level. Now those sound comparisons are available online as audio files.

All four models, rated at 17 kW, were subjected to the same evaluations by a nationally recognized testing firm. The noise output in decibels from each generator was measured at 7 locations around the unit, each at a distance of 7 meters away. The generators were run at 3600 RPM with loads of 0, 3, 7, 8 and 17 kW.

The test results were reported in a previous blog post here. But now you can check out the sound comparisons for yourself at powertobuilders.com.
