Тезис

Specifies a method for measuring the sound pressure levels on a measurement surface enveloping the noice source. 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. Cancels and replaces the first edition, which has been technically revised.
