This harsh sound is called "howling", or "feedback gain". The reasons for this phenomenon are as follows:
① The speaker has a peak at a certain frequency in the sound characteristics. The peak value in the three red circles is the root cause of whistling. What happens when there is a peak? The microphone will continuously receive the peak value, and the audio will continuously replay the peak value. Many times a second, the peak value will be infinitely amplified until the equipment is damaged.
② The input signal is too large to distort the released sound and cause howling. In the final analysis, it is the first reason. Ok, here is a small editor to tell you how to solve this problem.
① Use good microphone and sound.
Why do you say that? Because the sound characteristics of good sound and microphone are very smooth, this smoothing does not mean that its curve is straight. But the slope of the waveform is too smooth. In this way, there will be no hairdressing filtering, and there will be no narrow band peaks, and whistling will naturally occur rarely.
② The microphone should not be too close to the stereo and should not point to the stereo. In this way, even whistling points with certain frequencies can be effectively avoided.

③ Use the equalizer to reduce the whistling point that can be found by several db, so that the comb can become a smooth wave curve in the sound curve. This also reduces the chance of howling. These basic considerations are sufficient in daily applications.
