Audio feedback is the ringing noise (often described as squealing, screeching, etc) sometimes present in sound systems. It is caused by a “looped signal”, that is, a signal which travels in a continuous loop. In technical terms, feedback occurs when the gain in the signal loop reaches “unity” (0dB gain).
