F Bibliography
Specifies a method for measuring the sound pressure levels on a measurement surface enveloping a noise, in essentially free field conditions near one or more reflecting planes, in order to calculate the sound power level produced by the noise source. Coverage includes acoustic environment, measurement of sound pressure levels, instrumentation, and installation and operating of source under test. Also gives detailed definitions and annexes.
