Why does the monitor earphone emit a howling sound?

For LARK MAX 2
The reason cause of howling produced by a wireless microphone is the feedback loop of the sound, that is, after the microphone picks up the sound from the Speaker, the signal is repeatedly amplified to form a closed loop. The following are the specific reasons and corresponding solutions:
  1. Improper position of microphone and speaker
    1. Reason: The microphone is too close to the speaker (monitor headset) or the mic points directly at the speaker, causing the sound to be repeatedly picked up and amplified.
    2. Solution: Adjust the position of the microphone and speaker to avoid the two being too close.
  1. Gain (volume) set too high
    1. Cause: The microphone sensitivity is set too high, causing the signal to be over-amplified, triggering feedback.
    2. Solution: appropriate to reduce the microphone gain, TX gain small.
