6.1通路通用平面环绕声系统的研究

Study on 6.1 channel general planar surround sound system

提出了一种新的６．１通路环绕声系统及系统的两种不同的信号馈给法。通过理论和实验证明了系统可重发水平面内３６０°的声像，特别是侧向和后方的声像效果较现有的５．１通路系统有明显的改善，因而适合作为通用的环绕声系统。文中同时证明了新系统与５．１通路系统完全兼容，利用现有的方法即可实现信号的兼容记录与重发。

This paper proposes a new 6.1 channel surround sound system and its signal mixing methods. Theoretical and experimental results show that the system is able to recreate 3600 sound image in horizontal plane. Especially,compared with current 5.1 channel system, lateral and rear images of the new system are obviously improved. Therefore it is suitable to be used as a general surround sound system. It is also proved that the new system is fully compatible with 5.1 channel system. Current methods are available to record 6.1 channel signals.
