ABSTRACT:
In acoustic systems, especially with hearing aids, feedback whistling keeps occurring. To avoid this, a limit gain frequency response of the amplification device, which represents the limits of feedback whistling, is thus recorded. On the basis of the curve recorded a required gain frequency response with a number of interpolation points is created, with each interpolation point having a predetermined minimum distance in each case to the limit gain frequency response in at least two different directions. This enables feedback whistling to be largely avoided, even with shifts in resonant frequencies.
