Abstract: A method of conducting a fitting session for fitting a hearing device to a hearing device user's needs is provided. The method comprises S1. providing an estimate of, a current feedback from said output transducer to said input transducer, while the hearing device is in an operational state; S2. evaluating said estimate of a current feedback and providing a value of a feedback risk indicator in dependence of said estimate of a current feedback; S3. determining whether said value of the feedback risk indicator fulfils a high-risk criterion; and S4. if said high-risk criterion is fulfilled providing at least one of a warning, a recommendation, and an action in relation to said feedback risk. Steps S1 to S4 are configured to be automatically performed as background processes.
Thereby a simplified scheme for fitting a hearing device to a user's needs may be provided.

Abstract: A hearing aid includes an input unit, an output unit, a signal processing unit connected to said input unit and output unit, where the input unit, the signal processing unit and the output unit are forming 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 control unit configured to reduce a risk of howl due to acoustic, electrical, and/or mechanical feedback of an external feedback path from the output unit to the input unit of said hearing aid, where the hearing aid is configured to receive motion data characterising movement and/or acceleration and/or orientation and/or position of the hearing aid to control processing.

Abstract: 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.
