    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: The application relates to a hearing device comprising an ITE-part adapted for being located at or in an ear canal of a user, a configurable signal processing unit for processing an input signal, and a feedback estimation unit for providing a current estimate of an acoustic feedback path from an output transducer to an input transducer, a memory for storing frequency dependent reference estimates of the acoustic feedback path the real ear to coupler difference, when the ITE-part is correctly mounted, an optional probe signal generator for generating a probe signal at least in a specific measurement mode, wherein the hearing device is configured to perform measurement of the current estimate of the acoustic feedback path. The hearing device further comprises a control unit operatively connected to said memory and to said signal processing unit, and configured to compare said current estimate of the acoustic feedback path with said reference estimate of the acoustic feedback path, and to provide a current feedback path difference measure, and to determine a current estimate of real ear to coupler difference from the current feedback path difference measure. This has the advantage facilitating the mounting of the ear ITE-part. The invention may e.g. be used in hearing aids for compensating a user's hearing impairment.

    Abstract: A hearing aid includes a forward path for processing sound from the user's environment. The forward path includes a) a first microphone providing a first electric input signal representing sound as received at the first microphone, the first microphone being located away from an ear canal of the user, b) an audio signal processor for processing the first electric input signal, or a signal or signals originating therefrom, and for providing a processed signal, c) an output transducer for providing stimuli perceivable as sound to the user in dependence of the processed signal, and d) a second microphone configured to provide a second electric input signal representing sound received at the second microphone, the second microphone being located at or in the user's ear canal, and e) a feature extractor for extracting acoustic characteristics of the user's ear from the second electric input signal, or a signal originating therefrom.

    Abstract: A hearing system comprises a hearing device, e.g. a hearing aid or a headset, configured to be worn by a user. The hearing device comprises at least one input transducer for providing at least one electric input signal representative of sound in the environment of the hearing device, wherein said at least one electric input signal comprises a target signal component assumed to be of current interest to the user, and a noise component. The hearing device further comprises a noise control system configured to provide an estimate of said target signal component and an estimate of said noise component and to apply a statistical structure to said noise component to thereby provide a modified noise component comprising said statistical structure; and to determine a modified estimate of said target signal component in dependence of said modified noise component. Thereby an improved segregation of sound sources may be provided.

    Abstract: A binaural hearing aid system includes first and second hearing aids configured to be worn by a user at or in respective first and second ears of the user, each of the first and second hearing aids including: at least one input transducer configured to pick up a sound at the at least one input transducer and to convert the sound to at least one electric input signal representative of the sound, the sound at the at least one input transducer including a mixture of a target signal and noise; a controller for evaluating the sound at the at least one input transducer and providing a control signal indicative of a property of the sound; a transceiver configured to establish a communication link between the first and second hearing aids allowing the exchange of the control signal between the first and second hearing aids; a transmitter for establishing an audio link for transmitting the at least one electric input signal, or a processed version thereof, to another device. The controller is configured to: transmit the locally provided control signal to, and receive a corresponding remotely provided control signal from the opposite hearing aid via the communication link, and to compare the locally provided and the remotely provided control signals and to provide a comparison control signal in dependence thereof, and to transmit the at least one electric input signal, or a processed version thereof, to the another device via the audio link in dependence of the comparison control signal.

    Abstract: A hearing aid includes an input providing an input signal representing sound in an environment, the input signal including no speech signal, or one or more speech signals from one or more speech sound sources and additional signal components, termed noise signal, from one or more other sound sources, an own voice detector, a voice activity detector, and a talker extraction unit to determine and/or receive one or more speech signals as separated one or more speech signals from speech sound sources other than the hearing aid user and to detect the speech signal originating from the voice of the user. The talker extraction unit provides separate signals, each including, or indicating presence of, one of the one or more speech signals. A noise reduction system determines speech overlap and/or gap between the speech signal originating from the user's voice and each of the separated one or more speech signals.
