Measurement of Small Impairments of Perceptual Audio Coders Using a 3-Facet Rasch Model

Authors: Moulton, David; Moulton, Mark

AES Convention 104 · Paper 4709 · May 1998

Abstract

The subjective measurement of small audible differences has been hampered by experimental conflict between applicability and reproducibility. The Rasch Model offers a unique means of controlling the statistical analysis of experimental data in order to maximize reproducibility and applicability across listeners, audio material, and devices under test. The authors describe their testing of five codecs for Lucent Technologies.
