| Research Abstract |
AVS is a method of localizing a sound image aside even by two loudspeakers in front of a listener. In this study, it was found that (1) by searching ICLD and ICTD, the sound image localized aside even in strong lateral reflections, (2) an allowance of ICTD was found, which cannot be explained by conventional theory of sound image localization, (3) three speeches reproduced by AVS shows same easiness of hearing as reproduced those by three loudspeakers separately.
