Abstract: A binaural hearing system comprises a first and second hearing aids. The hearing aids each comprises antenna and transceiver circuitry allowing the exchange of audio signals between them. At least one of the hearing aids comprises primary and secondary adaptive 2-channel beamformers each providing a spatially filtered signal based on first and second beamformer-input signals. The primary and secondary 2-channel beamformers are coupled in a cascaded structure. In an embodiment, the spatially filtered signal of the secondary 2-channel beamformer may comprise an estimate of user's own voice. In an embodiment, the spatially filtered signal of the secondary 2-channel beamformer may comprise an estimate of a target signal in the environment. In an embodiment, the inputs to the secondary 2-channel beamformer may be beamformed signals from the first and second hearing aids respectively.

Abstract: A hearing aid comprises a resulting beam former (Y) for providing a resulting beamformed signal YBF based on first and second electric input signals IN1 and IN2, first and second sets of complex frequency dependent weighting parameters W11(k), W12(k) and W21(k), W22(k), and a resulting complex, frequency dependent adaptation parameter β(k). β(k) may be determined as / +c), where * denotes the complex conjugation and (·) denotes the statistical expectation operator, and c is a constant, and wherein said adaptive beam former filtering unit (BFU) comprises a smoothing unit for implementing said statistical expectation operator by smoothing the complex expression C2*·C1 and the real expression |C2|2 over time. Alternatively, β(k) may be determined from the following expression β = w C ⁢ ⁢ 1 H ⁢ C v ⁢ w C ⁢ ⁢ 2 w C ⁢ ⁢ 2 H ⁢ C v ⁢ w C ⁢ ⁢ 2 , where wC1 and wC2 are the beamformer weights representing the first (C1) and the second (C2) beamformers, respectively, Cv is a noise covariance matrix, and H denotes Hermitian transposition. Corresponding methods of operating a hearing aid, and a hearing aid utilizing smoothing β(k) based on adaptive covariance smoothing are disclosed.

Abstract: A hearing device, e.g. a hearing aid, comprises a) an input unit comprising a1) at least one first input transducer for picking up said sound user and providing respective at least one first electric input signals, and a2) a second input transducer for picking up said sound and providing a second electric input signal, the second input transducer being located at or in an ear canal of the user; b) an output unit comprising an output transducer for converting a processed electric signal representing said sound to a stimulus perceivable by said user as sound; c) a near-field beamformer applied to said multitude of electric input signals and implementing a feedback suppression system for suppressing feedback from said output unit to said at least one first input transducer, and comprising an adaptation unit for modifying the second electric input signal in approximation of an acoustic transfer function, or an impulse response, from the second input transducer to the at least one first input transducer and providing a modified second electric input signal representative of an estimate of said feedback. This has the advantage of allowing an increased gain to be applied to the input sound signal without a risk of feedback. A method of operating a hearing device is furthermore provided.

Abstract: A hearing device, e.g. a hearing aid, comprises first and second separate, interconnectable parts comprising first and second input transducers, respectively, for providing first and second electric input signals, respectively, representative of sound in an environment of the user, and a beamformer filtering unit configured to provide a spatially filtered signal based thereon, and a memory comprising a previously determined own voice transfer function corresponding to a target sound source located at said user's mouth. The hearing device is configured to determine an updated own voice transfer function according to activation of a predefined trigger, when the user's own voice is present, and to store an updated own voice transfer function in said memory. The hearing device further comprises at least one combination unit configured to apply a first multiplication factor to at least one of the first and second electric input signals, and a control unit configured to determine the first multiplication factor so as to decrease, e.g. minimize a difference measure representative of a difference between the previously determined own voice transfer function and the updated own voice transfer function.

Abstract: The disclosure relates to binaural hearing instruments and more particularly to reduction of processing time required in a binaural hearing aid system. According to the disclosure, there is provided a method comprising mono-directional transmission of data blocks comprising audio and/or information frames from one hearing instrument to the other hearing instrument or vice versa in a binaural hearing aid. According to the disclosure, the direction of transmission is determined by a quantity characterizing the presence of usable information content in the sound signal picked up by the hearing instruments of the binaural hearing aid. It is proposed to use one or more of local SNR, local voice activity detection indication, local level, local speech intelligibility estimate to determine the direction of transmission, although other quantities may be used.
