Patent ID: 8923540

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, wherein the forward path includes a signal processing unit configured to modify an electrical input signal to a specific hearing profile over a predefined frequency range, the predefined frequency range includes 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 restricting loop gain to a predetermined value in each band, the electrical feedback path includes an adaptive filter configured to estimate acoustical feedback from the output to the input transducer in each band, the hearing aid system further includes a relatively slow online feedback manager unit configured to, with a predefined update frequency, identify current feedback gain in each frequency band of the feedback path, and to subsequently adapt the maximum forward gain values IG max in each of the frequency bands in accordance with a predefined scheme, and 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.
