There are many reasons for echo, one is the unreasonable design of indoor sound reinforcement environment, the other is the unreasonable layout of speakers, and the third is the poor debugging of sound equipment and sound system. Specifically, it includes the following four aspects:
(1) The microphone is directly placed in the radiation area of the speaker, and its axis is directly aligned with the speaker.
(2) Sound reflection is serious in the sound reinforcement environment, and the surrounding and ceiling are not decorated with sound-absorbing materials.
(3) The sound equipment is mismatched, the signal reflection is serious, the connecting wire is faulty, and the sound signal flows through the contact point.
(4) Some audio equipment is in critical working state, and oscillation occurs when the sound signal is large.
Acoustic feedback is a headache in stage sound reinforcement. Whether in theatres, venues or song and dance halls, once acoustic feedback occurs, it will not only destroy the normal working state of the entire sound system, destroy the sound quality, but also destroy the effect of meetings and performances. Therefore, the suppression of acoustic feedback is an extremely important problem that must be paid attention to in the debugging and application of sound reinforcement system. Audio workers should understand acoustic feedback and find better ways to avoid or minimize the howling caused by acoustic feedback
In addition, if there are many different types of speakers in a sound system, and there is no electronic frequency divider, and different types of speakers use full frequency signals without frequency division, there will be a lot of frequency superposition and repetition between different speakers. Speakers. In this part, the acoustic interference will also become very serious, the sound will become blurred, the sound field is very poor, and the microphone is prone to sound feedback.
If the electronic frequency divider is used for reasonable frequency division, different loudspeakers will be in good working condition, and the sound frequency range between different loudspeakers will hardly repeat, so as to reduce the mutual interference of sound waves. The sound will become particularly clear, and the timbre will be better and more layered!
