Title Acoustics - Determination of sound power levels of noise sources - Precision methods for broad-band sources in reverberation rooms
Original title Acoustique - Détermination des niveaux de puissance acoustique émis par les sources de bruit - Méthodes de laboratoire en salles réverbérantes pour les sources à large bande [in French]
Bibliographic information International Organization for Standardization, Case postale 56, 1211 Genève 20, Switzerland, 21 Jan. 1988. 16p. 14 ref.
Abstract This international standard specifies in detail 2 laboratory methods for determining the sound power radiated by a source. It applies primarily to sources which produce steady broad-band noise. Contents: definitions; test room requirements; instrumentation; installation and operation of sources; measurement of mean-square sound pressure; calculation of sound power level. Annexes include a test room qualification procedure for the measurement of broad-band sound, and characteristics and calibration of a reference sound source.
