Extended Definition of Adaptive Feedback Cancellation
Adaptive feedback cancellation is an audio feedback cancellation method commonly used in hearing aids, which uses an adaptive filter to cancel feedback from a microphone. Feedback is defined as a system of inputs and outputs creating a feedback loop. Audio feedback is a positive feedback loop and is responsible for screeching noises heard from speakers and hearing aids.

Description of Adaptive Filter
The adaptive filter is an algorithm unique to adaptive feedback cancellation and it is used to mitigate audio feedback. Research for the ideal adaptive filter is ongoing but the basic principle is cancelling the total mechanical and audio feedback from a microphone.

=== Phases in the Adaptive Feedback Cancellation Process ===


 * 1) Understand audio feedback
 * 2) Create an algorithm to cancel audio feedback
 * 3) Implement that algorithm in a device where a microphone and speaker are connected
