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 sound capture device configured to be worn by a person and/or to be located on a surface is configured to pick up target sound from a target sound source s. The sound capture device comprises a) an input unit providing a multitude of electric input signals, each comprising a target signal component and a noise signal component; b) a directional noise reduction system comprising a beamformer unit coupled to said multitude of input signals and configured to provide an estimate of the target sound s. The beamformer unit comprises b1) target maintaining, reference beamformer providing a current reference signal; and b2) a target cancelling beamformer providing a current target cancelling sign. The directional noise reduction system is configured to operate in at least two modes in dependence of a mode control signal, 1) in a directional mode and 2) in a non-directional, omni-directional mode. The sound capture device further comprises c) antenna and transceiver circuitry for establishing an audio link to another device, and to transmit said estimate of the target sound s to said another device, and d) a mode controller for determining said mode control signal in dependence of said current reference signal and said current target cancelling signal. A method of operating a sound capture device is further disclosed.
