Elimination of acoustic feedback using an adaptive filter algorithm slot.

摘要

Techniques are presented to reduce unwanted acoustic feedback in a space that is performed by an algorithm of adaptive filter adjusts a notch (S12, S20) to a series of values ​​of different notch to position feedback. The results performing the algorithm with different values ​​of notch are compared (S26). Based on the comparison, the algorithm parameters are adjusted to process the input signals to reduce feedback.
