| 中文摘要: |
| 本文提出采用无耳壳、封闭耳道的头相关传输函数(HRTF)进行虚拟声信号处理的方法。理论分析表明,在包含功率均衡的扬声器虚拟声信号处理中,采用无耳壳、封闭耳道的头相关传输函数可有效地减少信号处理函数的谷点,从而减少声重发的音色改变．心理声学的实验结果表明,新处理方法的声像定位与传统的带耳壳、耳道的HRTF处理无显著区别,但音色较后者有所改善．因而新的方法更适合实际的虚拟声信号处理应用。 |

| A new virtual sound signal processing algorithm using pinna-less HRTF mea- sured by the blocked-ear-cannel method is proposed.Theoretical analysis demonstrates that the pinna-less HRTF can effectively cancel the zeros of signals processing function in power equalization,and therefore,decrease the change of timbre in reproduction.Results of psychoacoustic experiment also show that the HRTF without pinnae has almost the same localization effect as the HRTF with pinnae,while has less change in timbre. |
