Abstract: A hearing aid microphone system includes M microphones providing corresponding electric input signals. Environmental sound at a given microphone includes a target sound signal propagated via an acoustic propagation channel from a direction to or a location of a target sound source to the microphone, and possible additive noise signals. The acoustic propagation channel is modeled. The hearing aid system includes: a processor connected to the microphones, and a database Θ having a multitude of dictionaries Δp, p=1, . . . , P, where p is a person index, of vectors, termed ATF-vectors, whose elements ATFm, m=1, . . . , M, are frequency dependent acoustic transfer functions representing direction- or location-dependent, and frequency dependent propagation of sound. The processor is configured to, at least in a learning mode of operation, determine personalized ATF-vectors based on the multitude of dictionaries Δp, the electric input signals, and the model of the acoustic propagation channels.

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 device, e.g. a hearing aid, adapted for being located at or in an ear, or to be fully or partially implanted in the head, of a user, the hearing device comprises a) an input unit providing at least two input audio data streams, each comprising a mixture of a target signal component from a target sound source and a noise component from one or more noise sources; b) a mixing processor for receiving said at least two input audio data streams, and for mixing said at least two input audio data streams, or processed versions thereof, and for providing a processed input signal based thereon; c) an output unit providing output stimuli perceivable to the user as sound based on said processed input signal or a processed version thereof. The processor is configured to process said noise component of said at least two input audio data streams, or processed versions thereof in order to reduce or avoid artefacts in said processed input signal due to said mixing. A method of operating a hearing device is further disclosed. The invention may e.g. be used in hearing aids, e.g. hearing aids configured to communicate with another device, e.g. binaural hearing aid systems.

Abstract: A hearing device adapted to be worn by a user and for picking up sound containing the user's own voice is provided. The hearing device comprises a) an input unit comprising first and second input transducers for converting sound to first and second electric input signals, respectively, representing said sound; b) a processor configured to receive said first and second electric input signals and to provide a combined signal as a linear combination of the first and second electric input signals, wherein the combined signal comprises an estimate of the user's own voice, and c) wherein said hearing device is configured to provide that said first and second input transducers are located on said user at first and second locations, when worn by said user; and d) wherein said first and second locations are selected to provide that said first and second electric signals exhibit substantially different directional responses for sound from the user's mouth as well as from sound from sound sources located in an environment around the user. A method of operating a hearing device is further disclosed. Thereby an improved quality of an own voice estimate may be provided.

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.
