Acoustic Feedback Cancellation and Suppression
https://www.vocal.com/echo-cancellation/acoustic-feedback-cancellation-and-suppression/
Acoustic Feedback Cancellation and Suppression. Acoustic feedback can be well demonstrated by the public address system, as illustrated in the following diagram. When the microphone and speakers are positioned in close distance and oriented in a certain direction, howling may occur. In those situations people usually make howling disappear by varying the microphone orientation.

The audio signal at the top has been recorded in a room where sound reinforcement is used at moderate amplifier gain with the Acoustic Feedback Canceller switched OFF. In this case the coupling between the loudspeaker and microphone is already too high and oscillation at around 5.8 kHz and many other frequencies are easily excited.

Advanced Feedback Suppression (AFS) takes the guesswork out of controlling feedback, which is not only annoying but can even damage speakers – and ears. AFS is flexible and easy to use: just choose the level of suppression you want, and you’re done. AFS automatically stops feedback in its tracks. Products.

You may also be able to reduce the feedback loop by selecting the Enhancement tab in the microphone's properties page and enabling one of the following options: Enable Noise Suppression. Enable Acoustic Echo Cancellation. Note: These settings are audio hardware and software specific and may not be available for all microphones.

Adaptive feedback cancellation. The AFC concept consists in placing an FIR adaptive filter F ^ ( q, t) in parallel with the acoustic feedback path, having the far-end signal as its input and the microphone signal as its desired signal, see Fig. 1 (b).
Acoustic Feedback Cancellation For Public Address Systems
https://ccrma.stanford.edu/~eberdahl/Projects/FeedbackCancellation/FeedbackCancellation.pdf
PA systems are often plagued by acoustic feedback, which is also sometimes referred to as howling. This occurs when the signal in the feedback loop grows unboundedly, or at least until elements of the system begin clipping. Since howling is usually very loud, it is unpleasant. Here systems for canceling acoustic feedback are investigated.
