    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.

    Abstract: The present invention regards a hearing aid device at least one environment sound input, a wireless sound input, an output transducer, electric circuitry, a transmitter unit, and a dedicated beamformer-noise-reduction-system. The hearing aid device is configured to be worn in or at an ear of a user. The at least one environment sound input is configured to receive sound and to generate electrical sound signals representing sound. The wireless sound input is configured to receive wireless sound signals. The output transducer is configured to stimulate hearing of the hearing aid device user. The transmitter unit is configured to transmit signals representing sound and/or voice. The dedicated beamformer-noise-reduction-system is configured to retrieve a user voice signal representing the voice of a user from the electrical sound signals. The wireless sound input is configured to be wirelessly connected to a communication device and to receive wireless sound signals from the communication device. The transmitter unit is configured to be wirelessly connected to the communication device and to transmit the user voice signal to the communication device.

    IPC: H04R25/00

    Abstract: A hearing aid configured to be worn by a user, the hearing aid comprising a user interface allowing the user to control functionality of the hearing aid, and a feedback sensor for repeatedly providing a feedback signal indicative of a current estimate of feedback from an output transducer to an input transducer of the hearing aid, wherein the user interface is based on changes to the current estimate of the feedback path, e.g. provided by the user. A method of operating a hearing aid is further disclosed. Thereby an alternative user interface for a hearing aid may be provided. The invention may e.g. be used in hearing aids or headsets, or a combination thereof.

    Abstract: A hearing system comprises a hearing device, e.g. a hearing aid, configured to be worn by a particular user at or in an ear, or to be fully or partially implanted in the head at an ear of the user. The hearing device comprises at least one microphone for converting a sound in the environment of the hearing device to an electric input signal. The hearing system, e.g. the hearing device, comprises a processor comprising an own voice analyzer configured to characterize the voice of a person presently wearing the hearing device based at least partly on said electric input signal, and to provide characteristics of said person's voice, and an own voice acoustic channel analyzer for estimating characteristics of an acoustic channel from the mouth of the person presently wearing the hearing device to the at least one microphone based at least partly on said electric input signal, and to provide characteristics of said acoustic channel of said person. The hearing system further comprises a user identification unit configured to provide a user identification signal indicating whether or not, or with what probability, the person currently wearing the hearing device is said particular user in dependence of said characteristics of said person's voice and said characteristics of said acoustic channel of said person.

    Abstract: A hearing system comprises a hearing device worn on the head, or fully or partially implanted in the head, of a user, and external audio transmitters. The hearing system allows wireless communication to be established between the hearing device and the audio transmitters. The hearing device comprises microphones providing respective electric input signals; a beamformer filter providing a beamformed signal from the electric input signals; and an output unit. The hearing system further comprises a selector/mixer for selecting and possibly mixing one or more of the electric input signals or the beamformed signal and external electric signals from the audio transmitters, and providing a current input sound signal based thereon for presentation to the user. The selector/mixer is controlled by a source selection processor, which determines the source selection control signal based on a comparison of the beamformed signal and the external electric sound signals or processed versions thereof.
