Listening room specifications exist to make psychoacoustic test results comparable across sites

Evidence

A number of specifications for listening room acoustics and loudspeaker set-ups therein have been proposed. The main purpose for such specifications is to make the results of psychoacoustic listening tests conducted in rooms comparable between different academic and industrial sites. The specifications are relatively detailed. For example, ITU-R BS.1116-1 (1997) gives the details for the geometry of the room, the reverberation time, the amount of allowed background noise, the loudspeaker set-up geometry, listening positions, and audio system performance. Most of the values are given with tolerance rates, like how much the reverberation time can deviate from the optimal value depending on frequency. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1817
