What is Feedback?
Feedback is the “squealing” or “howling” generated between microphones and loudspeakers. Feedback occurs if a mic is too close to the front of a loudspeaker.
One way to avoid feedback is through proper microphone and loudspeaker placement. The best strategy is to place microphones near the origin of the sound to be reinforced and physically as far from, and behind the loudspeakers as possible.
