Noise Level Information

Most WINCO generators are powered by gasoline, natural gas, LP gas or diesel engines. Depending upon the engine and generator design some models are noisier than others. Consider each model's noise characteristics before purchasing.

How Does WINCO Measure Noise Levels

There are several different methods for measuring noise levels. At WINCO we like to keep things simple and honest. Our published noise ratings are always taken at an industry standard seven meter distance (about 23 feet). The unit is placed in the center of an open area and measurements are taken with a calibrated meter on all sides. We also do not have our published dB ratings at "normal household load" or in an exercise mode. Our standard ratings are always at full load at seven meters for a true operational rating. Look for specific model ratings on the appropriate specification sheet.

When selecting an installation site for a generator the environment can affect the level of noise from the machine. Hard walls and concrete area do not absorb noise well while lawns and other vegetation can be useful sound absorbers.
