Abstract: A hearing aid comprises 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 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.
