Answer: Feedback, also known as the Larsen effect, occurs when the amplified sound from any loudspeaker reenters the sound system through an open microphone and is amplified again and again, causing a loop.

What causes feedback on a microphone?
Microphone feedback is a positive gain loop between a microphone and a loudspeaker. Speakers amplify the mic signal, and then the mic picks up the sound from the speakers. This positive gain loop continues and the system overloads, resulting in the terrible screech of microphone feedback.
How do I get rid of microphone feedback?
12 Methods To Prevent & Eliminate Microphone/Audio Feedback.
- Do Not Position The Microphone In Front Of A Loudspeaker.

Can feedback damage speakers?
Yes it can if unchecked. Not because it’s ‘feedback’ but because of the consequences. When you get severe feedback, it often results in a high level tone at the frequency that’s causing the feedback. It may result in overdriving one of your speakers, usually a high frequency driver.
How does audio feedback work?
The continuous sound created by the initial resonance that ends up coming out of the speakers is then picked up by the microphone, which creates a circular audio loop that amplifies its own frequency—and creates the uncomfortable, high-pitched screech known as feedback.
How does a feedback suppressor work?
Automatic Feedback Suppression works like this: The algorithm monitors incoming audio for signs of feedback; when it detects feedback behavior, it places a narrow notch filter at each frequency that feeds back, reducing the gain of that frequency.
Why am I getting feedback on my computer speakers?
Feedback is frequently caused when speakers face the microphone or a reflective surface — like a window or mirror. Halt this continuous sound looping with a slight repositioning of either device.
