  an indoor sound field can be divided into three kinds of voices: the first is the direct sound; the second is the early reflection sound; the second is the reverberation sound.
1, direct sound:
In our ear in the direct sound is the direct sound, it is easy to understand, we must be the location near the sound source, it may be as much as possible to hear the direct sound. In the process of communication, the direct sound is not affected by the indoor reflection interface, we now require the direct sound as much as possible the use of speakers in the field of design, the reasonable control of the reflected sound, in order to achieve the perfect effect.
2, early reflection sound
Refers to a sound, a sound, a sound field around the interface after two or several times after the reflection of sound, early reflected sound and direct sound delay time is not more than 70ms, more than 70ms of the human ear can hear the sound and reverberation sound box. In the sound field, the appropriate early reflection sound can make the sound more vigorous and plump.
In 3, in the reverberant sound
He is in the reverberant sound early reflected sound after the arrival of the sound field, the sound reflection interface. The suitable reverberation sound can make the sound has the different environment feeling, is advantageous in enhances the sound fullness; the too strong reverberation sound can destroy the sound clarity.
