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 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.

Abstract: An adaptive level estimator for providing a level estimate of an electric input signal representing sound is provided. The adaptive level estimator comprises a first level estimator that provides a first level estimate of the electric input signal in a first number K1 of frequency bands; a second level estimator that provides attack/release time constants associated with a second level estimate of the electric input signal in a second number K2 of frequency bands, wherein K2 is smaller than K1; and a level control unit that provides a resulting level estimate based on said first level estimates and said attack/release time constants associated with said second level estimates. The level estimator may be used in devices or applications that benefit from a dynamic adaptation of an input signal level to a listener's dynamic range of sound level perception, or to any other specific dynamic range deviating from that of the environment sound.
