Shangqiu stage sound equipment prices Zhengzhou 1, into the dual-channel technology (binaural) single speaker system, the source of the sound is always a position, we all of a sudden be able to determine its location, multi-speaker systems of the past, they rely on while voices from different locations, to trick the brain for sound location identification. Two-channel system by two different signal processing sound, ears accepted, and mistaking it reaches the two ears of different signal is sent from the same location, in order to determine a sound position . Stereo and obviously this is the essential difference. Different and stereo, when two external speakers are used to send the two-channel effects, sound must be sent to a particular ear, rather than as two speakers sound to both ears at the same time like a stereo. Is the difference between this sound localization accuracy between the two key factors. Shangqiu stage sound equipment prices Zhengzhou Tel Jiaming Yang 1503 +71780 +75 QQ2579114209 two speakers to produce a true 3D sound is very difficult. First, the effect of such a position is vulnerable the listeners position of different and greatly reduced; Secondly, the audience proved the exact location of the two speakers will sound stream two shares a sense of location identification resentment. Most successful from an external sound source transmitted able to accurately express directional sound system with four speakers configuration, but unfortunately even with four speakers rarely system is really in the 4-way 3D sound, and the use of 4-channel crosstalk cancellation technology. The vast majority of systems are two stand alone 1111 dual-channel design, and then mixed front and rear speakers audible stereo. Moreover only the front speakers with a true 3D sound, while other parts are to be mixed with the traditional 4-channel or surround sound.

When a voice in the audience side of the body, the closer this side of the ear can hear a greater voice, and can advance a little to hear. This difference in the acoustics two terms IAD (Inter-aural Amplitude Difference) and ITD (the Inter-aural Time Difference) to be described. The brain is relying on these two subtle differences to determine the location of the sound. The inherent shape of the ears will actually enhance or weaken a different sound frequencies. Rely on the the voice location of different, external ear, is responsible for the solution to the different front and rear direction, because the ears are forward, natural in front of the sound will be bigger, while the back will be smaller. And because of the shape of the outer ear up and down asymmetry can also take this sound to determine the height of the Shangqiu stage sound equipment prices Zhengzhou Tel Jiaming Yang 1503 +71780 +75 QQ2579114209
