Description

The objective of this Standard is to specify a method for determining the sound power level or sound energy level of a noise source by comparing measured sound pressure levels emitted by a noise source (machinery or equipment) mounted in situ in a reverberant environment, with those from a calibrated reference sound source.

Scope

This International Standard specifies a method for determining the sound power level or sound
energy level of a noise source by comparing measured sound pressure levels emitted by a noise source
(machinery or equipment) mounted in situ in a reverberant environment, with those from a calibrated
reference sound source. The sound power level (or, in the case of noise bursts or transient noise
emission, the sound energy level) produced by the noise source, in frequency bands of width one octave,
is calculated using those measurements. The sound power level or sound energy level with frequency
A-weighting applied is calculated using the octave-band levels.
