立体声耳机重发中头中定位效应的消除

Elimination of Effect of Inside-The-Head Localization In Sound Reproduction by Stereophonic Earphone

探讨双通路立体声耳机重发中头中定位效应的消除。实验结果表明，如果仅用人头传输函数（HRTF）对声音信号进行处理，能产生一定的声像方向感，但还不能很好地消除头中定位效应。而通过加混响信号使声像有深度感，可在一定程度上起到改善的作用。

This paper studies the method of eliminating the effect of inside-the-head local- ization in sound reproduction by stereophonic earphone. Experimental result shows that procesed audio signal only with HRTF can create sound image in certain directional impression but can not completely eliminate the effect of inside-the-head localization. If suitable reverberation is added to the signal, the effect can be eliminated to some extent.
