Subjective listening tests of digital audio codecs rely on a panel of expert listeners. Experience has shown that members of the listening panel vary in their sensitivities to the various types of coding artifacts. The paper describes the development of psychoacoustic techniques designed to characterize these listeners in order to predict their sensitivities to audio reproduction defects. Results of subjective tests show that expert listeners typically have enhanced sensitivity to one or more particular classes of coding artifacts.
