FEEDBACK ELIMINATION IN A HEARING AID

FEEDBACK ELIMINATION IN A HEARING AID

A hearing aid includes an input unit, an output unit, a signal processing unit connected to the input unit and output unit, where the input unit, the signal processing unit and the output unit form part of a forward path of the hearing aid, where the signal processing unit is configured to apply a f...

description A hearing aid includes an input unit, an output unit, a signal processing unit connected to the input unit and output unit, where the input unit, the signal processing unit and the output unit form part of a forward path of the hearing aid, where the signal processing unit is configured to apply a forward gain to the at least one electric input signal or a signal originating therefrom. The hearing aid further includes a feedback reduction unit configured to reduce risk of howl due to acoustic, electrical, and/or mechanical feedback of an external feedback path from the output unit to the input unit. The feedback reduction unit is configured to modulate the forward gain in time to provide that the forward gain exhibits an increased or unchanged forward gain in one or more first time periods and a reduced forward gain in one or more second time periods.
