How does microphone feedback work?
In: Technology
A bit of sound enters the mic, plays out the speaker which is then picked up by the mic. Oh course the speaker will play that again like an echo almost but feedback does this thousands of times a second-playing the sound and picking back up, repeat.
I cannot explain for certain why the tone climbs to a higher pitch; but I have, for fun, held a mic up to a speaker when it’s really quiet and still seems to happen when close enough.
