Acoustics - Determination of sound power levels and sound energy levels of noise sources using sound pressure - Engineering methods for an essentially free field over a reflecting planeMore info
Specifies methods for determining sound power level or sound energy level of a noise source from sound pressure levels measured on a surface enveloping the noise source (machinery or equipment) in a space that approximates an acoustic free field near one or more reflecting planes. Sound power level or in the case of noise bursts or transient noise emission, sound energy level produced by the noise source in frequency bands or with A-weighting applied is calculated using those measurements.
