Scope

This International Standard specifies a direct method and a comparison method for determining the sound power level pro-duced by a source. It specifies test room requirements, source location and operating conditions, instrumentation and tech-niques for obtaining an estimate of mean-square sound pressure from which the sound power level of the source in oc-tave or one-third octave bands is calculated.
