Abstract

Abstract The purpose of this paper is to investigate whether or not the degree of interaural cross-correlation can be widely applied as a physical factor to estimate auditory source width (ASW) perceived in any sound field. Results of two hearing tests infer the following. ASW perceived in different sound fields with the same degree of interaural cross-correlation are equal to each other, regardless of number and arriving direction of reflection. But, ASW perceived in a sound field where a direct sound arrives from 30°, 60° and 90° in azimuth is narrower than ASW in a sound field where a direct sound arrives from the front direction.
