When the speaker sound in a room

When the speaker sound in a room, the bookshelf speaker can hear directly from the speaker's voice, this is the direct sound field (indirectfield), but can also be heard from the wall, ceiling and floor reflected sound, this is called reflection sound field (reverberantfield). Listeners hear the direct sound field, reflect the voice of the sound field, the more hours, the sound is better, because the voice of the sound field can be controlled directly, but reflect the voice of the sound field is unable to control, can only put the direct a breeder to sound and bookshelf computer speaker, originally the clarity of sound is reduced, so sit nearer the speakers closer to the audience will feel a little better sound effect, and the audience is likely to be in the rear they heard the reflection of sound more sound than the direct sound field, sound effect will be more bad and lower resolution. Sometimes a band performance on the stage, because they are not listening to the speaker, and on both sides of the main sound box is positioned near the location of the mouth, bands and singers have heard no sound from the direct sound field put, they don't stand position is called direct sound field, sound effect will not good, of course, this will also affect the band's performance level, make the audience hear is not very good performance.
