Description
Sets out a survey method for determining the weighted sound power level of a device or a machine. The method should not be used when it is feasible to use a more precise method, e.g. where a laboratory hemi-anechoic room is available for the measurements. The method requires that the background noise be at least 3 dB lower than the noise produced by the source.
