Title Acoustics - Measurement of the in situ sound attenuation of a removable screen
Original title Acoustique - Mesurage de l'atténuation acoustique in situ d'un écran amovible [in French]
Bibliographic information International Organization for Standardization, Case postale 56, 1211 Genève 20, Switzerland, 1997. iv, 10p. Illus. 9 ref.
Abstract This international standard specifies methods for evaluating the in situ sound attenuation performance of a removable screen, either indoors or outdoors. This engineering grade method is based on an insertion loss measurement that can be carried out either with shielding of the actual sound source(s) or using an artificial sound source. Contents: scope; normative references; definitions; instrumentation; determination of in situ sound attenuation; uncertainty; information to be recorded; information to be reported.
