Specification of a survey method for measuring the sound pressure levels produced at specified measurement points by the noise source under test and by a reference sound source. The sound power level of the source under test is calculated form the measured values of the sound pressure level by using environmental corrections. These environmental corrections are calculated from the differences between the values obtained with a reference sound source and those given by its calibration.
