ANSI/ASA S12.55-2006 / ISO 3745:2003

This American National Standard specifies methods for measuring the sound pressure levels on ameasurement surface enveloping a noise source in anechoic and hemi-anechoic rooms, in order todetermine the sound power level or sound energy level produced by the noise source. It givesrequirements for the test environment and instrumentation, as well as techniques for obtaining thesurface sound pressure level from which the sound power level or sound energy level is calculated,leading to results which have a grade 1 accuracy.

The methods specified in this American National Standard are suitable for measurements of all typesof noise.

The noise source can be a device, machine, component or sub-assembly. The maximum size of thesource under test depends on the radius of the hypothetical sphere (or hemisphere) used as theenveloping measurement surface.
