First, rule out whether the speaker is too near to the microphone, and whether the distance is more than 3 meters. Check to see if the speaker volume or microphone volume is too loud, and try turning the volume down. The volume can be adjusted according to the on-site environment to meet the needs. If the volume of the speaker is too large, it will not only damage the hearing of the students, but also easily produce howling.
