摘要
本文考虑了双耳相位差的高级近似,导出了在中频情况下也适用的具有更普遍意义的立体声声像定位公式。新的公式在低频时将简化为通常的正弦定理,而随着声音频率的增加,声像位置将与声音的频率有关。文中还给出了频率上限(1500Hz～1700Hz),当声音的频率高于此上限时,单靠双耳相位差就难以决定立体声的声像位置。文中最后还给出了上述理论的实验验证。
In this paper, by considering the higher approximation of binaural phase differ-ence, a more general localization equation for stereo sound image which is applicable to mid-fre-quency is derived. At low frequency, this equation can be simplified to the stereo law of sines, but as the frequency increases the sound image position has reference to frequency. A frequency high-limit (1500～1700Hz) is assumed. When the frequency of sound is higher than this limit,it is difficult to determin the sound image position by simply using the binaural phase difference.At last, the experimental verification is given to the above-mentioned theory.
