  1. Microphone and speaker are used at the same time;

  2. The sound played by the stereo can be transmitted to the microphone through space;

  3. The sound energy from the speaker is large enough, and the pickup sensitivity of the microphone is high enough.

  Unnegligible howling hazard

  Once howling occurs, it will cause that the volume of the microphone channel cannot be increased. The howling will be very serious after the volume is increased, which will have a bad impact on the live performance. When the critical point of howling is reached, the sound will ring when the microphone is turned on. The sound will have a reverberation sense, which will damage the sound quality; In severe cases, the speaker or power amplifier will be burnt due to strong signal. It is not uncommon to burn the tweeter unit of the speaker due to howling, because in the howling state, strong signals will cause clipping (top cutting) distortion of the power amplifier and generate a large number of high-frequency harmonics. If the tweeter unit cannot withstand such strong high-frequency signals, the voice coil will be burned; In addition, in the howling state, if the output of the power amplifier is overloaded, it may also be burned.

  How to restrain howling?

  Whistling is a special acoustic problem of sound reinforcement system, which cannot be completely eliminated. In practice, audio experts have summarized many methods to suppress the squeal of the audio system. By taking effective measures and using some electroacoustic equipment, the aim of suppressing, reducing and eliminating the squeal is achieved. The idea is to avoid the three conditions of simultaneous squeal of the audio system.

  1. Make the sound of the speaker difficult to transmit to the microphone.

  a. Keep the microphone away from the speaker.

  b. Decrease the volume of the microphone. If the microphone volume is too high, the probability of ringing will increase. Reduce the volume in time to avoid howling. another

  In addition, if you want to hold or wear a microphone through the speaker, you should also pay attention to controlling the volume, otherwise you will cause serious howling due to too close distance.

  c. Make rational use of the directional characteristics of speakers and microphones

  Both the microphone and the speaker are directional. If the microphone is not used in the radiation area of the speaker, the sound of the speaker will not be easily transmitted to the microphone; Similarly, if the speaker is not in the pickup area of the microphone, it is difficult for the microphone to pick up the sound of the speaker. Therefore, by properly adjusting the angle of the speaker, making it avoid the playback area of the speaker when using the microphone, or making the sound radiation area of the speaker do not overlap with the use area of the microphone, you can suppress whistling.
