Sound Power Levels of Noise Sources in Anechoic and Hemi-Anechoic Rooms, Determination of
Describes a precision method for determination of the sound power levels of noise sources in laboratory anechoic or hemi-anechoic rooms. The standard contains information on instrumentation, installation, and operation of the source; methods for determination of the sound pressure level on the measurement surface; procedures for the calculation of sound power level, directivity index, and directivity factor; and techniques that may be used to qualify the laboratory facilities used for the measurements.
