<p>Techniques for reducing unwanted acoustic feedback in a space are carried out by an adaptive filter algorithm that adjusts a notch (S12, S20) to a plurality of different notch values in order to locate feedback. The results obtained by performing the algorithm at various notch values are compared (S26). Based on the comparison, the parameters for the algorithm are adjusted for processing of the input signals to reduce the feedback.</p> |
