Acoustics. Determination of sound power levels of noise sources using sound pressure. Engineering methods for small, movable sources in reverberant fields - Methods for special reverberation test rooms1 Scope This document specifies a relatively simple engineering method for determining the sound power levels of small, movable noise sources. The methods specified in this document are suitable for measurements of all types of noise within a specified frequency range, except impulsive noise consisting of isolated bursts of sound energy which are covered by ISO 3744 and ISO 3745. NOTE A classification of different types of noise is given in ISO 12001.
