ANSI/ASA S12.33-1990 (R1997)

Vendor Note: This standard describes an engineering method for determination of octave-band or A- weighted sound power levels of noisesources in a special reverberation test room. The standard contains information on instrumentation, installation, and operation ofthe source, procedures for the selection of a measurement surface, methods for the determination of space- time average soundpressure level, procedures for the calculation of sound power level, and techniques that can be used to design the specialreverberation test room and to qualify the measurement environment.
