Title Acoustics - Determination of sound power levels of noise sources using sound pressure - Precision methods for reverberation rooms
Original title Acoustique - Détermination des niveaux de puissance acoustique émis par les sources de bruit à partir de la pression acoustique - Méthode de laboratoire en salles réverbérantes [in French]
Bibliographic information International Organization for Standardization (ISO), Case postale 56, 1211 Genève 20, Switzerland, 3rd ed., 1999. vi, 32p. 28 ref.
Abstract This international standard specifies laboratory methods for determining sound power radiated by sources as a function of frequency, using a reverberation test room having specified acoustical characteristics. The method is suitable for steady noise with broad-band, narrow-band and discrete-frequency components. The noise may be emitted from a device, machine, component or sub-assembly.
