Background technology
Usually, " stereo " is the abbreviation of " stereo sound ", refers to three dimensional sound.Therefore, briefly, stereophonic sound system is exactly the system that is made up of two passages (for example, left and right passage).Comparatively speaking, only the system that is made up of single channel is called as " monophonic " system.
Because binaural effect, majority can both tell the intensity of the sound that transfers to two ears and the difference in propagation time, determine the direction of sound source with this.In other words, because people's ear is positioned at the both sides of head, so the effect of and sound that time difference hear big or small according to acoustic pressure is different.Because this binaural effect, even microphonia, people also can tell the direction and the distance of sound.
Stereophonic sound system is utilized people's this binaural effect, and a pair of microphone is arranged apart with left and right sides passage as the bilateral ear, is similar to the sound sense that has ambient environment effects of people's ear with realization, thereby makes the audience think that he just at the scene.More lively with the stereo sound of recording than sound with recorded in mono.If hear stereo sound in position, then can make its effect reach maximization.Therefore, up to the present, record substantially or reproduction mode in all using this stereo mode.
With reference to Fig. 1, the audio signal that receives in the microphone of a pair of the above-mentioned type is transferred to a pair of loud speaker of arranging with preset distance (for example, 2 or 3 meters) each interval 1 and 2, so that loud speaker 1 and 2 is reproduced as sound S1 and S2 with this audio signal.When the user is positioned at the summit P of adjacent triangle (this leg-of-mutton base is limited by this line of drawing between to loud speaker 1 and 2), and listen to simultaneously by loud speaker 1 and 2 sound S1 and the S2 that reproduce, sound S1 and the ears of S2 with different intensity and time arrival user, thus he can feel to have reproduced seemingly the position of sound source.According to the position of distance between loud speaker 1 and 2 or listener summit P of living in, transmit sound intensity and time change.Therefore, on degree, has difference by loud speaker 1 and 2 sound that reproduce, this difference is determined according to the position (that is the position of vertex of a triangle P) and the angle θ that the position limited of user and loud speaker that the distance between loud speaker 1 and 2, user listen to sound.The degree difference (level difference) that reproduces has changed the frequency of synthetic video, thereby obtains stereophonic effect.
Like this, as shown in Figure 1, position and distance difference between the loud speaker 1 and 2 of reproduced sound signal S1 and S2, promptly position and distance difference provide the key factor of perfect stereophonic effect.If the distance between the microphone on two passages less than the predetermined confined value, then will reduce stereophonic effect to a great extent.If audience's position is away from the loud speaker 1 and 2 that is located at the place, fixed position, then he may be difficult to the distance of perceived sounds.Like this, sound is not distinguished exactly, thereby perfect stereophonic effect can not be provided.
