| 摘 要： | 提出了立体声重发声像的相关理论分析法。通过对双耳听觉互相关函数的计算，得到声重发时双耳声信号的时间差以及听觉互相关系数Ｉ，从而对声像位置和声像的明晰度进行分析，得到了同主观评价实验相一致的结果。

| Abstract: | This paper proposes a method of correlation theoretical analysis on stereophonic sound image. By calculating interaural cross-correlation function, interaural time difference and cross-correlation coefficient I for sound reproduction are obtained. Therefore, the position as well as definiteness of sound image is analysed. These theoretical results are in agreement with those of subjective assessment experiments. |
