Abstract: A hearing device with an adjustable vent is disclosed. The device includes at least one microphone configured to provide an input signal representing sound, a processor configured to process the input signal and provide a processed signal, at least one loudspeaker configured to receive the processed signal from the processor and to provide an acoustic signal based on the processed signal to the ear of a user, an earpiece comprising a vent, and an electrically controllable valve configured to control the vent, and a valve control unit configured to receive one or more control signals in dependence of a current hearing situation of the hearing device, wherein the valve control unit is configured to adjust the electrically controllable valve in dependence of the one or more control signals to provide the vent to be in a state between an acoustically more open and an acoustically less open state.

Abstract: 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.

Abstract: A hearing aid includes at least two microphones, providing respective at least two electric input signals representing sound around the user; a filter bank converting the electric input signals into signals as a function of time and frequency; a directional system connected to the microphones and being configured to provide a filtered signal in dependence of the 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 the microphones is selected as a reference microphone, thereby providing a reference input signal for each frequency band. The reference microphone may be selected in dependence of directional data related to directional characteristics of the microphones. The reference microphone may be different for at least two frequency bands. The reference microphone may be adaptively selected based on a logic criterion.
