Abstract

A virtual auditory space can be presented to a listener by synthesizing binaural signals with head-related transfer functions and reproducing the signals at listener's ears. Especially, a transaural system is able to realize the binaural signal reproduction with two or more loudspeakers by utilizing a crosstalk canceller. In the transaural system, however, a listener is forced to be still while listening because the crosstalk canceller is highly sensitive to listener's head movements. This paper proposes a dynamic transaural system that responds to a listener's head rotation using non-contact head tracking. A localization experiment was performed with the developed system. The experimental results show that source directions are perceived accurately when the listeners are allowed to rotate their heads with the system, thereby indicating that the system works correctly with a listener's head rotation.
非接触式头部跟踪动态跨耳复制系统的研制
通过合成具有头部相关传递函数的双耳信号,并在听者耳中再现该信号,可以将虚拟听觉空间呈现给听者。特别是,跨耳系统可以利用串音消除器实现两个或多个扬声器的双耳信号再现。然而,在穿耳系统中,听者在听时被迫保持静止,因为相声消除器对听者的头部运动高度敏感。本文提出了一种动态跨耳系统,该系统使用非接触式头部跟踪来响应听者的头部旋转。利用开发的系统进行了定位实验。实验结果表明,当听者随系统旋转头部时,可以准确地感知到源方向,从而表明该系统在听者旋转头部时工作正确。
