A study for 3D audio technique to share immersive space

AVS是一种将声音图像局部化的方法，即使是在听众面前的两个扬声器。本研究发现：(1)通过搜索ICLD和ICTD，即使在强侧向反射的情况下，声像也被局部化；(2)找到了ICTD的余量，这是传统的声像定位理论所不能解释的；(3)用AVS再现的三个语音表现出与分别用三个扬声器再现的相同的易听性。

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.
