Hi-Fi Tests-with 1/3 Octave Pink Weighted Random Noise

Authors: Møller, Henning

AES Convention 47 · Paper A-5 · March 1974

Abstract

Measurements on Hi-Fi systems are relevant when they give the same results as listening tests. The measuring method most suited for this requirement is the 1/3 octave, pink weighted, random noise method used in the actual listening room. Another consideration may be phase response. When this method is used in the actual room, it gives information about the combination loudspeaker-room. Measurements on five different speakers in three different rooms show a considerable room dependence, but good correspondence with listening tests; that is, the combination loudspeaker-room must be optimized. In practice the measurements can be carried out in many ways, the simplest method requiring only a test record and a portable sound level meter.
