The Sound Power is defined as the energy rate of sound emitted per unit of time from any sound source. The normal hearable sound level for Human beings spans from 10-12 W to 10 - 100 W, a range of 10 / 10-12 = 1013. The below given Sound Power Level Chart provides you with the Sound Power and the Sound Power Level from some common sound sources. This Table of Sound Level of Sound Sources helps us to know the power levels of different sound sources.
