Acoustics. Determination of sound power levels of noise sources using sound pressure. Engineering methods for small, movable sources in reverberant fields. Methods for special reverberation test rooms (British Standard)
Cancels and replaces ISO 3743 (1988). Specifies a relatively simple engineering method for determining the sound power levels of small, movable noise sources. In this direct method the A-weighted sound power level of the source under test is determined from a single A-weighted sound pressure level measurement at each microphone position, rather than from a summation of octave-band levels. This method eliminates the need for a reference sound source, but requires the use of a special reverberation test room.
