Feedback cancellation is a process used in audio systems to eliminate unwanted feedback loops that can cause distortion or audio artifacts, often employing adaptive filtering techniques. It is crucial in hearing aids, public address systems, and telecommunication devices to improve sound quality and prevent the annoying 'howling' noise caused by feedback.
