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.

Abstract: A hearing device, e.g. a hearing aid, comprises first and second hearing device parts having separate first and second housings and being electrically connectable by a connecting element. The second hearing device part is available in a multitude of variants. The connecting element comprises an electric cable comprising a multitude of electric conductors, and a first electric connector comprising a multitude of first electric termination elements. The second hearing device part comprises a loudspeaker, and/or a number of sensors each providing an electric sensor signal representative of a current property of the environment of the hearing device and/or a current state of the user wearing the hearing device. The first hearing device part comprises a configuration extractor electrically connected to said second hearing device part via said connecting element and adapted to identify a current configuration of sensors in said second hearing device part.
