标准简介

Specifies a procedure to determine sound power levels of sound sources in situ, especially if non-movable. A comparison method is used, with all measurements carried out in octave bands. Measurement uncertainty depends on the test environment. This is evaluated by comparing with an indicator describing the spatial sound distribution. The accuracy will either be that of an engineering method or a survey method. Primarily applies to sources which radiate broad-band noise. May also be used for sources radiating narrow-band noise or discrete tones, although the measurement uncertainty might become larger than stated.
