Sound Quality Analyzer conducts psychoacoustic loudness analysis of audio WAV files.
Loudness (sones) – A measure of the perceived sensation of the volume of a sound. The loudness of the sound considers not only the level of the sound but the frequency composition of the sound. Broadband sounds will have a lower loudness than narrowband signals for a given level. Loudness in Sones is a linear quantity, meaning that a sound with a Loudness of 2 Sones is perceived as twice as loud as a sound with a Loudness of 1 Sone. Loudness has been standardized in the ISO 532B standard.
