摘要:
在用声像法求双耳房间冲激响应的过程中融入了个人化与头相关传递函数,研究了基于个人化双耳房间冲激响应的外部化虚拟声系统.首先通过个人人体参数获取个人化与头相关传递函数,然后用声像法得到前4阶个人化的早期双耳反射声,最后截取前80 ms早期反射声作为个人化双耳房间冲激响应加入到虚拟声系统.主观测听实验结果表明,使用假人双耳房间冲激响应可以改善头中效应而不降低定位精度,而使用个人化双耳房间冲激响应不仅可以改善头中效应,而且可以提高近13%的定位精度.
Abstract:
An externalized virtual sound localization system based on personalized binaural room impulse response(PBRIR)is proposed to simulate spatial hearing environment. To obtain the PBRIR, personalized head related transfer functions(HRTFs)were used in the image method. First, personalized HRTFs were obtained via the anthropometrics measurement; secondly, image method was applied to obtain the first four-order personalized reflections; finally, only the first 80ms of those reflections were remained as the PBRIR. Subjective listening experiments were designed and the results show that out-of-head localization can be obtained without decreasing the localization accuracy when the dummy head binaural room impulse response(BRIR)is used. When the PBRIR is used, the out-of-head localization is improved, and the localization accuracy is increased of about 13 percent.
