Abstract: A binaural hearing system comprising left and right hearing devices is provided, each comprising an input unit providing an electric input signal representing an environmental sound; a noise reduction system for estimating and reducing a noise component of the electric input signal; antenna and transceiver circuitry allowing the exchange of data between the hearing devices. The binaural hearing system is—in a mode of operation, where a sound source is predominantly audible at a first one of the hearing devices—configured to transmit the estimate of the noise component determined in a second one of the hearing devices to the first hearing device and to use said estimate to reduce the noise component in the electric signal of the first hearing device and to provide a noise reduced signal in the first hearing device. Thereby improved noise reduction is provided for use, e.g. in hearing aids, in non-symmetric acoustic situations.

Abstract: The application relates to a hearing device comprising a beamformer of the generalized sidelobe canceler (GSC) type. The application further relates to a method of operating a hearing device. The disclosure addresses a problem which occurs when using a GSC structure in a hearing device application. The problem arises due to a non-ideal target-cancelling beamformer. As a consequence, a target signal impinging from the look direction can—unintentionally—be attenuated by as much as 30 dB. To resolve this problem, it is proposed to monitor the difference between the output signals from the all-pass beamformer and the target-cancelling beamformer to control a time-varying regularization parameter in the GSC update. This has the advantage of providing a computationally simple solution to the non-ideality of the GSC beamformer. The invention may e.g. be used in hearing aids, headsets, ear phones, active ear protection systems, or combinations thereof.

Abstract: The application relates to a binaural hearing assistance system comprising left and right hearing assistance devices, and a user interface, to its use and to a method. The left and right hearing assistance devices comprises a) at least two input units for providing a time-frequency representation of an input signal in a number of frequency bands and a number of time instances; and b) a multi-input unit noise reduction system comprising a multi-channel beamformer filtering unit operationally coupled to said at least two input units and configured to provide a beamformed signal. The binaural hearing assistance system is configured to allow a user to indicate a direction to or location of a target signal source relative to the user via said user interface. This has the advantage that interaural cues of the target signals can be maintained, while the ambient noise is reduced.

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.

Abstract: A method of operating an audio processing device to improve a user's perception of an input sound includes defining a critical frequency fcrit between a low frequency range and a high frequency range, receiving an input sound by the audio processing device, and analyzing the input sound in a number of frequency bands below and above the critical frequency. The method also includes defining a cut-off frequency fcut below the critical frequency fcrit, identifying a source frequency band above the cut-off frequency fcut, and extracting an envelope of the source band. Further, the method identifying a corresponding target band below the critical frequency fcrit, extracting a phase of the target band, and combining the envelope of the source band with the phase of the target band.
