根据立体声重放系统的波前再现能力来考察它的性能。提出了一种新的声像定位理论,并用它得出了对高频段也适用的更有普遍意义的立体声正弦定律。考察了中央声像消失现象并证明其分析结果与主观感受的一致性。建立了频率界限,高于此频率时,立体声系统将不再提供高保真重放。为了验证所提之理论,给出了一些实际结果。
According to the stereo reproduction system wavefront reproduction ability to examine its performance. A new theory of sound image localization is put forward and used to derive the more generalized sinusoidal law of stereo that is also applicable to high frequency bands. Examines the disappearance of the central sound image and proves the consistency of its analysis results and subjective feelings. A frequency limit was established above which the stereo system will no longer provide hi-fi playback. In order to verify the proposed theory, some practical results are given.
