: Brown Technical

: 1110000017055

: Book


The purpose of this standard is to provide the methodology for the determination of Sound Power Levels of noise sources using the sound intensity method. The standard contains information on instrumentation, installation and operation of the source and procedures for the calculation of Sound Power Level. This standard describes the methodology for determination of Sound Power Levels of broad-band, and/or discrete-frequency noise sources using the intensity method. It is based on sound tests utilizing the sound intensity method as described in ISO 9614-1 (measurement at discrete points, grade 2) or ISO 9614-2 (measurement by scanning, grade 2).
