Hearing Aid Acoustic Feedback Solution #5 – Notch Filtering Because acoustic feedback is not evident at all high frequencies, it would appear appropriate to reduce gain at the specific frequency or frequency range at which it occurs, without affecting significantly adjacent frequencies. A technique to perform this is the use of a notch filter. A…
