Acoustics. Determination of sound levels of noise sources. Precision methodes for broad-band sources in reverberation rooms
Specification of a direct method and a comparison method for determining the sound power level produced by a source. It specifies test room requirements, source location and operating conditions, instrumentation and techniques for obtaining an estimate of mean-square sound pressure from which the sound power level of the source in octave or one-third octave bands is calculated. It applies primarily to sources which produce steady broad-band noise as defined in ISO 2204.
