Patent ID: 8503705

Claim:
A hearing aid system comprising: an ear-mould for a child, an input transducer, a forward path, an output transducer and an electrical feedback path, the forward path comprising a signal processing unit for modifying an electrical input signal to a specific hearing profile over a predefined frequency range, wherein the predefined frequency range comprises a number of frequency bands, for which maximum forward gain values IG max for each band are stored in a memory, the maximum forward gain values IG max used to restrict loop gain to a predetermined value in each band, the electrical feedback path comprising an adaptive filter for estimating acoustical feedback from the output to the input transducer in each band, wherein the hearing aid system further comprises a relatively slow online feedback manager unit for—with a predefined update frequency—identifying current feedback gain in each frequency band of the feedback path, and for subsequently adapting the maximum forward gain values IG max in each of the frequency bands in dependence thereof in accordance with a predefined scheme, wherein the predefined update frequency is smaller than or equal to 0.01 Hz, and wherein the relatively slow online feedback manager unit is configured to reduce the risk of howling by decreasing the maximum forward gain values IG max in said ear-mould for a child.
