Control of auditory distance perception based on the auditory parallax model

摘要

Simulation of the distance of a sound image within 2 m from a listener, in the absence of reflec- tions and a loudness cue, was investigated. To do this, a model named the "auditory parallax model', which focuses on the role of parallel angle information involved in head-related transfer functions (HRTFs), was examined with psychoacoustical experiments. For purposes of com- parison, experiments were also done on an actual sound source, sound with digitally synthe- sized HRTFs, and sound with the interaural time difference (ITD) and interaural level difference (ILD) synthesized by the Hirsch-Tahara model.
