Sound power levels are ideal for creating sound ratings since they are independent of environment The common analogy used is to compare sound power levels with the watt rating of a light bulb Using a lamp with a 100 watt bulb does not tell you how much light will hit the paper you wish to illuminate since this depends on many variables However knowing the characteristics of the
