Abstract: A hearing aid system may include an ear-mould for a child, an output transducer, and an electrical feedback path. A forward path includes a signal processor that modifies an electrical input signal to a specific hearing profile over a predefined frequency range which includes a number of frequency bands. Maximum forward gain values IGmax for each band are stored in a memory, restricting loop gain to a predetermined value 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, and to subsequently adapt the maximum forward gain values IGmax in each of the frequency bands in accordance with a predefined scheme. The feedback manager unit is thus reduces the risk of howling by decreasing the maximum forward gain values IGmax in said ear-mould for a child.
