Scope

This International Standard specifies a method for measuring the sound pressure levels on a measurement surface envelonping the source in order to calculated the sound power level produced by the noise source.It gives requirements for the test environment and instrumentation as well as techniques for obtaining the surface sound pressure level from which the sound power level of the source is calculated,leading to results which have a grade 3 accuracy. It is important that specific noise test codes for various types of equipment be established and used in accordance with this International Standard.For each type of equipment,such noise test codes will give detailed requirements on mounting,loading and operating conditions for the equipment under test as well as a selection of the measurement surface and the microphone array as specified in this International Standard.
