摘要
在基于耳机的虚拟听觉重放中,头相关传输函数滤波会引起音色损伤,需要增加音色均衡的信号处理。但均衡处理可能会对虚拟源定位有负面影响。因此需要通过综合主观评价,对各种均衡方法及参数进行评价与优选,从而在音色和定位两方面做一定的折衷。本文在使用通用和定制HRTF两种情况下,比较不同音色均衡方法的效果。相应的实验表明,在耳机稳态虚拟听觉重放中,功率均衡法可明显改善重放音色,且在音色与定位方面是较好折衷。
In headphone-based virtual auditory display,head-related transfer function filtering may cause timbre damage,which requires additional signal processing for timbre equalization.However,equalization may have a negative effect on virtual source localization.Therefore,it’s necessary to evaluate and select equalization methods and parameters through comprehensive subjective evaluation,so as to make a certain compromise between timbre and localization.The present paper compares the perceptual performances of different timbre equalization methods using general and customized HRTF,respectively.The experimental results indicate that the power equalization is able to obviously improve timbre in the static virtual auditory display with headphone,and it provides good compromise between timbre and localization.
