【摘要】 声源定位因素包括双耳时间差、双耳声级差、谱因素等,文章在介绍声源定位因素的基础上,引出了人体头部相关传输函数HRTF定义及其特性。基于美国MIT Media Lab发布的HRTF数据库,利用计算机合成两声道虚拟三维音频,并对虚拟声源进行了定位测试实验,12名听觉正常者参与了主观听音实验,选取10个具有方位信息的音频信号作为刺激信号,听音者将听到的方位记录下来,与预设方位进行对比。最后对实验结果进行了总结分析。更多还原

【Abstract】 Binaural sound source localization factors including Interaural Time Difference,Interaural Level Differential,Spectral factors,et al. This paper introduces sound source localization factors first,and then leads to the human head- related transfer function HRTF’s definition and its characteristics. The raw data of HRTF are offered by MIT Media Lab and multi- media computers are used for generating virtual three- dimensional audio. In the virtual sound source localization test,12 subjects are hired for subjective listening test,and 10 directional audio signals are used as the stimulus signal. Subjects hear and record the position. Finally,the experimental results were analyzed.更多还原
