Acoustic-Image Lateralization Judgments with Binaural Tones

Abstract

Experiments on the lateralization of soundimages, established by binaural single or multiple tones, are reported. It is argued that the concept of soundimages having perceived position in an auditory space usefully describes relevant auditory experience and that the phenomena concerned can be conveniently parallelled by a correlation‐type fusion model. The concept is used to clarify effects such as the occurrence of multiple images, discontinuities of lateralization judgments, and the interacting influence of interaural time delay and amplitude difference.
