What is Feedback?

Feedback is the screeching/squealing/hooting sound heard when there is an accidental loop in the PA system. That is when the sound from a microphone is amplified and fed to the speakers and then picked up again by the microphone, this sound then carries on round and round resulting in the nasty noise. The feedback frequency depends on a number of factors such as: the resonant frequency of the room, distance of microphone and speakers, frequency response of the microphone, characteristics of musical instruments.
To reduce or eliminate feedback this loop needs to be broken, here are a few ways of doing that.
