FEEDBACK: A LOUD SQUEALING, SHRILL
OR HOWLING SOUND THAT IS SELF

•
Feedback occurs when a microphone is
too close to the speaker or the
microphone volume is too high, or the
microphone is pointed towards the
speaker. It is also caused by sound
reflecting off hard surfaces.
•
Reduce or eliminate Feedback by
- Pointing the microphone in a different
direction.
- Keeping the microphone BEHIND the
speakers.
- Turn down the volume levels.
