文中应用三维(立体)声场中,声像位置φ_I、θ_I与各扬声器位置φ_n~ψ、θ_n~ψ及其发出声音振幅An之间的关系,分析计算了一种六输出通路、一种四输出通路和普遍的多输出通路半三维空间立体声系统。从其分析的结果得知,声像在水平平面内没有位置畸变现象发生,而在竖直方向上却有位置不定或模糊的感觉。但是,各种声场的畸变情况却是等效的,并不因为系统不同而有本质上的区别。 文中也确定了,任何一个无声像位置畸变的立体声系统所须的独立信号m等于其声音的重发维数k加1,即 m=k+1
In the three-dimensional (stereo) sound field, the relationship between the sound image position φ_I, θ_I and each speaker position φ_n ~ ψ, θ_n ~ ψ and the sound amplitude An is analyzed. A six-output channel, Pathways and Universal Multiple Output Paths Semi-three-dimensional spatial stereo system. According to the result of the analysis, no distortion of the position of the sound image in the horizontal plane occurs, but the position of the sound image is indefinite or fuzzy in the vertical direction. However, the distortion of various sound fields is equivalent and does not differ essentially due to different systems. It has also been established that the independent signal m of any stereo system with no sound like position distortion is equal to the re-issued dimension k of its sound plus 1, ie m = k + 1
