ASA S12.5-2006 /ISO 6926:1999 (R2011) American National Standard Acoustics - Requirements for the Performance and Calibration of Reference Sound Sources Used for the Determination of Sound Power Levels

standard by American National Standards of the Acoustical Society of America, 12/18/2006

Full Description

Reference sound sources are used extensively in "comparison methods" for determining the noiseemissions of physically stationary sound sources. A reference sound source, of known sound poweroutput, is used to establish the numerical relationship between the sound power level of a source, in agiven location in a given acoustical environment and the space- and time-averaged sound pressurelevel at a set of microphone positions. Once that relationship is established, it is straightforward tomeasure the average sound pressure level produced by an "unknown source" and to determine thesound power level produced by that source.
