適用范圍：Describes a method for determining sound power levels of noise sources that emit broadband sound and/or discrete frequency sounds/tones using reverberation rooms. Applies when it's undesirable or unfeasible to move the source to decrease uncertainty of measurement. Described method requires reverberation room pre-qualification through test and requires use of comparison method to determine sound power levels. Specifies environment, procedures and equipment used to qualify the room by test.
