The composition and characteristics of stereo
Stereo sound refers to the sound with three-dimensional effect. The sounds in nature are stereo, but if we replay these stereo sounds after recording, amplifying, etc., all the sounds will come out from one speaker, and this replay sound (compared with the original sound source) is not stereo up. At this time, since all kinds of sounds are emitted from the same speaker, the original sense of space (especially the sense of spatial distribution of the sound group) also disappears. This playback is claimed to be monophonic. If the entire system from recording to playback can restore the original sense of space to a certain extent (it is impossible to restore completely), then this kind of playback sound with spatial distribution characteristics such as a certain degree of orientation and layering is called sound technology. stereo.
Composition
direct sound
Direct sound refers to the sound that travels directly to the left and right ears of the listener.
reflected sound
It refers to the sound that reaches the listener's ears after the first reflection from the indoor surface, about ten to tens of milliseconds later than the direct sound
Reverb sound
It means that after the sound is repeatedly reflected irregularly by various boundaries and obstacles in the hall, it forms a lingering reverberation that is directionless and permeates the entire space.
Stereo features
Compared with mono, stereo has the following advantages:
(1) Have a sense of orientation and distribution of each sound source
(2) Improve the clarity and intelligibility of information
(3) Improve the presence, layering and transparency of the program.
