The principle of howling: The microphone repeatedly picks the sound reproduced by the speaker to form positive feedback. When the volume exceeds a certain limit, this same frequency signal will cause the amplifier circuit to feedback and then howl will be generated
Causes of howling: The incident angle of the microphone is close to the radiation angle of the speaker, or the distance between the microphone and the speaker is too close, or the frequency response characteristics of the venue are not good
How to eliminate howling: Automatically track the feedback point frequency, automatically adjust the Q value bandwidth, automatically eliminate the sound feedback and maximize the protection of the sound quality
