This American National Standard describes a method for the determination of sound power levels of
noise sources that emit broadband sound and/or discrete frequency sounds/tones using reverberation
rooms. The standard applies when it is either undesirable or unfeasible to move the source to decrease
the uncertainty of the measurement. The method described requires reverberation room pre-qualification
through test and requires the use of the comparison method to determine sound power levels. This
standard specifies the physical environment, procedures, and equipment used to qualify the reverberation
room by test. Pre-qualifying the room ensures adequate modal density for the use of one source location
to obtain acceptable accuracy and repeatability of results. The reference sound source (RSS) used for
the comparison method relies on AHRI Standard 250 to accurately describe the requirements for and
characterize sound power of the RSS at all frequencies of interest.
