| 中文摘要: |
| 本文利用立体声像的相关理论分析方法;分析了用扬声器重发虚拟声时,倾听者的头部尺寸对声像定位的影响。结果表明,当实际倾听者的头部尺寸与虚拟声信号处理所用头部模型的尺寸有差别时,前方范围内的声像位置畸变较小,但侧向的声像位置畸变较大。因而本文特别指出,倾听者头部尺寸的不同是虚拟声重发时测向的声像位置畸变的重要原因。声像定位实验证实了理论分析。 |
| 英文摘要: |
| By using the method of correlation analysis of stereophonic sound image, this paper studies the effect of listener’s head size on virtual sound image localization in loudspeaker reproduction. It is shown that, when the size of listener’s head is different from that of head model used in the signal processing, the directional distortion of the front image is small, but the directional distortion of the side image is large. Therefore, an unmatched listener’s head size is the main cause of side image directional distortion in virtual sound reproduction. Results of sound image localization experiment verify the above theoretical analysis. |
