The sound intensity of generating sets fluctuates approximately between 60dB and 90dB at a distance of 7m from the sound source. Below, you will find a decibel chart, which allows you to compare the amount of decibel of a generating set with sounds of everyday life. In open air, the maximum sound intensity is 72dB(A) or 97LWA at a distance of 7m from the sound source.
Factors
There are various factors that can affect the amount of decibel:
- Type of engine
It is a well-known fact that engines make less noise than diesel engines, but more than gas engines. - Engine speed
1500rpm engines are quieter than 3000rpm ones. - Canopy
Generating sets with a canopy are quieter than open ones. - Air cooling or water cooling
Air-cooled engines make more noise than water-cooled ones.
