Title Acoustics - Determination of sound power levels of noise sources - Engineering methods for special reverberation test rooms
Original title Acoustique - Détermination des niveaux de puissance acoustique émis par les sources de bruit - Méthodes d'expertise en salles réverbérantes spéciales [in French]
Bibliographic information International Organization for Standardization, Case postale 56, 1211 Genève 20, Switzerland, 12 Jan. 1988. iii, 19p. Illus. 14 ref.
Abstract This international standard specifies relatively simple engineering methods for determining the weighted and octave-band sound power levels of small noise sources. The methods are not suitable for noise sources which emit impulsive noise consisting of single noise bursts. Contents: definitions; test room requirements; instrumentation; installation and operation of source; measurement of noise emitted by source; calculation of sound power levels. Annexes include characteristics and calibration of a reference sound source.
