Description

ASA S12.12 – American National Standard for Engineering Method for the Determination of Sound Power Levels of Noise Sources Using Sound Intensity.

This standard describes a method for in situ determination of the sound power level of noise sources in indoor or outdoorenvironments using sound intensity measurements. The standard contains information on instrumentation, installation andoperation of the source, procedures for the selection of a measurement surface, methods for the sampling of sound intensity onthe measurement surface, procedures for the calculation of sound power level, and techniques that can be used to qualify themeasurement environment.
