This International Standard specifies a method for determining the sound power levels of sound sources in situ, especially if non-movable. A comparison method is used and all measurements are carried out in octave bands. The measurement uncertainty depends on the test environment. The measurement uncertainty 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.
