为了改进三维空间环绕声重发系统中的一些缺点,文中提出一种三维声的4-4-8重发方式,以消除声象在重发中并不完全均称和应用全景声信号重发时产生摺变现象等缺点。此外,文中还简略地描述了三维声的菱体重发和棱锥重发两种方式;这与4-4-8重发方式可以视为分别是方形排列、菱形排列和三角形排列平面声重发体系在三维空间的推广。
In order to improve some shortcomings in three-dimensional surround sound retransmission system, a 4-4-8 retransmission method of three-dimensional sound is proposed in this paper to eliminate the incomplete symmetry of the sound image in retransmission and to apply the panorama signal retransmission When the phenomenon of change and other shortcomings. In addition, this paper also briefly describes the three-dimensional acoustic rhombic retransmission and pyramid retransmission two ways; This and 4-4-8 retransmission can be considered as square arrangement, rhombus arrangement and triangular arrangement plane acoustic retransmission system Promotion in three-dimensional space.
