More Information
Summary:A hearing aid adapted for being worn by a user comprises at least two microphones, providing respective at least two electric input signals representing sound; a filter bank converting the at least two electric input signals into signals as a function of time and frequency; a directional system connected to said at least two microphones and being configured to provide a filtered signal in dependence of said at least two electric input signals and fixed or adaptively updated beamformer weights. At least one direction to a target sound source is defined as a target direction. For each frequency band, one of said at least two microphones is selected as a reference microphone, thereby providing a reference input signal for each frequency band. The reference microphone for a given frequency band may be selected in dependence of directional data related to directional characteristics of the at least two microphones.
