摘要
提出了一种与5.1通路平面环绕声兼容的三维空间环绕声系统。声像定位分析与实验结果表明该系统可重发上半空间范围的声像。系统不但前后区域声像稳定,还改善了5.1通路系统侧向声像不稳定的问题,并且听音区域也较宽。该系统可以用于产生特殊声效和重现音乐厅的空间感效果。
A spatial surround sound system which is compatible with 5.1 channel horizontal surround sound system is proposed. The results of sound image analysis and experiment show that, the system is able to recreate sound image in the upper hemispherical space. It can not only reproduce stable image in the front and rear direction, but also eliminate the defect of poor lateral image of 5.1 channel system. Furthermore it has a wide listening area. Hence the system can be used to reproduce special 3D sound effect and the spaciousness of hall.
