Binaural speech transmission index with spatialized virtual speaker in near field: Distance and direction dependence
发布时间: 2020-08-10 浏览次数: 80

Abstract: As well as background noise and reverberation, speaker-to-listener relative location

affects the binaural speech transmission index (BSTI) considerably, especially in the

near field. To highlight how speaker location influences the BSTI, binaural room impulse

responses measured in a low-reverberation listening room are used to obtain the BSTI indirectly

and analyze its near-field dependence on distance and direction. The results show that

the BSTI based on the better-ear rule is higher when the virtual speaker is located laterally

rather than in the anterior or posterior. When the distance-dependent intensity factor is

introduced, the distance is the dominant factor, not the azimuth.
