ASA S12.55 – American National Standard Acoustics – Determination of sound power levels of noise sources using sound pressure – Precision methods for anechoic and hemi-anechoic rooms
This American National Standard specifies methods for measuring the sound pressure levels on ameasurement surface enveloping a noise source (machinery or equipment) in an anechoic room or ahemi-anechoic room. The sound power level (or, in the case of impulsive or transient noise emission,the sound energy level) produced by the noise source, in frequency bands of width one-third octave orwith frequency weighting A applied, is calculated using those measurements, including corrections toallow for any differences between the meteorological conditions at the time and place of the test andthose corresponding to a reference characteristic acoustic impedance.
