AES Convention 117 · Paper 6236 · October 2004

Abstract

The applications of an accurate objective measure of subjectively perceived loudness are many. Accordingly, the ITU-R has initiated a study to identify such a measure for a new recommendation. A new objective loudness measure based on modifications to a traditional psychoacoustic model of perceived loudness was developed for this study. When compared to subjective loudness matching data generated outside the ITU-R, the new measure is found to perform better than simpler weighted power measurements and the unmodified psychoacoustic model.
