| 摘 要： | 头相关传输函数（HRTF）是自由场情况下点声源到双耳的声学传输函数,包含有声源定位的主要物理信息,在双耳听觉物理的研究中是非常重要的.虚拟听觉重放是HRTF的一个重要应用,它采用HRTF信号处理的方法模拟声源到双耳声学传输过程,从而在声重放中产生相应的空间听觉事件.目前HRTF与虚拟听觉重放已成为物理学（声学）、信号处理、听觉生理等研究领域的热门与前沿课题,受到国内外多学科研究工作者的共同关注,并在众多的领域得到广泛的应用.该文综述HRTF与虚拟听觉重放的基本原理与国内外研究进展,并概述了虚拟听觉重放的一些重要应用.

| Abstract: | Head-related transfer functions （HRTFs） are acoustical transfer functions from sound source to two ears and embody the main cues for sound source localization. They are therefore vital to the researches on binaural hearing. One of the important applications of HRTFs is virtual auditory display, in which input stimulus is filtered by a pair of HRTFs and then reproduced by headphone to create spatial auditory events. HRTFs and virtual auditory display are now the hot topics in the fields of acoustics, signal processing and hearing and have been widely used. The present article reviews the principle and advance in HRTFs and virtual auditory display, including some recent works in China, and then outlines the main applications of virtual auditory display. |
