Full Description

This American National Standard specifies a method for determining the sound power level or soundenergy level of a noise source by comparing measured sound pressure levels emitted by a noise source(machinery or equipment) mounted in situ in a reverberant environment, with those from a calibratedreference sound source. The sound power level (or, in the case of noise bursts or transient noiseemission, the sound energy level) produced by the noise source, in frequency bands of width one octave,is calculated using those measurements. The sound power level or sound energy level with frequency Aweightingapplied is calculated using the octave-band levels.
