对非中心倾听位置的立体声像进行了理论和实验分析。结果表明,非中心倾听位置的声像定位结果和信号的频率有关。当倾听者偏离中心位置超过一定距离Xmax或信号频率超过某一上限fmax时,就有可能出现声像位置超出扬声器布置之外,从而破坏立体声的空间信息的情况。而Xmax和fmax是互成反比关系。缩小左右扬声器之间的张角或增加中置扬声器(如5.1通路系统)可扩大听音区域,提高声像的稳定性。 The theoretical and experimental analysis of stereo images of non-central listening positions was conducted. The results show that the non-central listening position of the sound image localization results and signal frequency. When the listener deviates more than a certain distance Xmax from the center position or the signal frequency exceeds an upper limit fmax, there is a possibility that the sound image position exceeds the speaker arrangement and the spatial information of the stereo sound is destroyed. While Xmax and fmax are inversely proportional to each other. Reduce the angle between the left and right speakers or increase the center speaker (such as the 5.1 channel system) to expand the listening area, improve the stability of the sound image.
