3D立体音效原理 传统的立体声喇叭只能让声音有左右的区别,且立体音场的表现都在两只喇叭中央的区域内,因此声音似乎都只由前方发出,感觉较为平面而且空间不足。而新一代的3D音效技术,是基于使用一对立体喇叭,采用数位讯号处理以及听觉心理学的原理,创造出三度空间音场的效果。其原理则是将音色经过数位讯号处理后,让左、右声道造出综合及差异音讯号,中央声音出现在总和讯号(左声道加右声道)内,反射或背景声音又出现在两种差异讯号(左声道减右声道、右声道减左声道)中,这些差异可提供方向感,并增强听者对空间的感觉,即使喇叭摆设于电脑荧幕两侧,也可明显感受到音场空间的扩大与层次
The 3D Stereo Sound Principle The traditional stereo speakers can only make a difference between sound and sound, and the performance of the stereo sound field is in the central area of the two speakers. Therefore, the sound seems to be emitted only from the front, which is more flat and space-less. The new generation of 3D audio technology, is based on the use of a pair of stereo speakers, using digital signal processing and auditory psychology to create a three-dimensional sound field effect. The principle is the sound through digital signal processing, so that the left and right channels to create integrated and differential audio signal, the central sound appears in the sum signal (left channel plus right channel), reflection or background sound again In the two different signals (left channel minus right channel, right channel minus left channel), these differences provide a sense of direction and enhance the listener’s sense of space, even if the speaker is placed on both sides of the computer screen, Can also clearly feel the expansion and level of sound field space
