Abstract: A hearing aid including a multitude M≥2 microphones adapted for providing M electric input signals (x) representative of an environment of a user, at least one beamformer for generating at least one beamformed signal in dependence of beamformer weights (w) configured to be applied to said electric input signals, thereby providing said at least one beamformed signal (Y) as a weighted sum of the M of electric input signals. The beamformer weights (w) are adaptively optimized to a plurality of target positions (θ) by maximizing a target signal to noise ratio (SNR) for sound from the target positions (θ). The signal to noise ratio may be determined in a number of different ways, e.g. in dependence of first and second output variances (|YT2, |YV|2) of said beamformer, when said electric input signals (x) or said beamformed signal (Y) are/is labelled as target (T) and noise (V), respectively.

Abstract: Disclosed herein are embodiments of a method performed by a hearing aid and a hearing aid including one or more processors, a memory, two or more microphones, and an output transducer. The hearing aid is configured to generate a first processed signal (y) based on input signals from the two or more microphones and a steering value, wherein a target direction is associated with the steering value. The steering value can be changed depending on certain criterion.

Abstract: A hearing device, e.g. a hearing aid, is configured to be worn by a user, e.g. fully or partially on the head of the user, comprises a) an input transducer for converting a sound comprising a target sound from a target talker and possible additional sound in an environment of the user, when the user wears the hearing device, to an electric sound signal representative of said sound, b) an auxiliary input unit configured to provide an auxiliary electric signal representative of said target signal or properties thereof, c) a processor connected to said input transducer and to said auxiliary input unit, and wherein said processor is configured to apply a processing algorithm to said electric sound signal, or a signal derived therefrom, to provide an enhanced signal by attenuating components of said additional sound relative to components of said target sound in said electric sound signal, or said signal derived therefrom. The auxiliary electric signal is derived from visual information, e.g. from a camera, containing information of current vibrations of a facial or throat region of said target talker, and the processing algorithm is configured to use the auxiliary electric signal or the signal derived therefrom to provide the enhanced signal.
