5.1通路(3/2)环绕声系统的改进
An improvement on the 5.1 channel (3/2) surround sound system
  
中文摘要:
      本文利用环绕声重发的声像定位理论,探讨了对5.1通路(3/2)环绕声系统的改进方法.理论和实验结果表明,通过改变系统现有的分立-对信号馈给方法,而采用文中所提出的新的信号馈给方法,就可以在一定的程度上克服现有方法的缺陷,使系统不但可重发稳定、明晰的前方声像,而且可重发稳定的侧向声像。并且听音区域有所扩大.因而改进后的系统既可用于伴随图像的声音重发,又可作为通用系统(兼容地)用于不伴随图像的声音重发.文中最后还讨论了系统信号的记录和传输问题.
英文摘要:
      By using the image localization theory for surround sound reproduction, this paper proposes a way to improve 5.1 Ch (3/2) surround sound system. Theoretical and experimental results show that, by changing current pair-wise signal fed and using a new signal fed, system is not only able to reproduce a distinct and stable front image, but also able to provide a stable side image. Listening area is also widened. Therefore, improved system can be used both for sound system with picture, and more generally, for sound system without picture compatically. Last, the problem of signal recorded and transmitted is also discussed.
