Abstract: A sound capture device configured to be worn by a person and/or to be located on a surface is configured to pick up target sound from a target sound source s. The sound capture device comprises a) an input unit providing a multitude of electric input signals, each comprising a target signal component and a noise signal component; b) a directional noise reduction system comprising a beamformer unit coupled to said multitude of input signals and configured to provide an estimate of the target sound s. The beamformer unit comprises b1) target maintaining, reference beamformer providing a current reference signal; and b2) a target cancelling beamformer providing a current target cancelling sign. The directional noise reduction system is configured to operate in at least two modes in dependence of a mode control signal, 1) in a directional mode and 2) in a non-directional, omni-directional mode. The sound capture device further comprises c) antenna and transceiver circuitry for establishing an audio link to another device, and to transmit said estimate of the target sound s to said another device, and d) a mode controller for determining said mode control signal in dependence of said current reference signal and said current target cancelling signal. A method of operating a sound capture device is further disclosed.

Abstract: The application relates to: A hearing system comprising first and second hearing aid systems, each being configured to be worn by first and second persons and adapted to exchange audio data between them. The application further relates to a method of operating a hearing system. The object of the present application is to provide improved perception of a (target) sound source for a wearer of a hearing device (e.g. a hearing aid or a headset) in a difficult listening situation. The problem is solved in that each of the first and second hearing aid systems comprising an input unit for providing a multitude of electric input signals representing sound in the environment of the hearing aid system; a beamformer unit for spatially filtering the electric input signals; antenna and transceiver circuitry allowing a wireless communication link between the first and second hearing aid systems to be established to allow the exchange of said audio data between them; and a control unit for controlling the beamformer unit and the antenna and transceiver circuitry; wherein the control unit—at least in a dedicated partner mode of operation of the hearing aid system—is arranged to configure the beamformer unit to retrieve an own voice signal of the person wearing the hearing aid system from the electric input signals, and to transmit the own voice signal to the other hearing aid system via the antenna and transceiver circuitry. This has the advantage of eliminating the need for a partner microphone while still providing a boost in SNR of a target speaker. The invention may e.g. be used for the hearing aids, head sets, active ear protection devices or combinations thereof.

Abstract: A hearing aid for comprises an ITE-module and a BTE-module. The ITE module is adapted for being located at or in an ear canal of a user and comprises functional elements for providing a normal function of the hearing aid. The BTE-module is adapted for being located at or behind an ear of the user and comprises a rechargeable battery for providing electric energy to the ITE-module. The hearing aid further comprises a connecting part for mechanically and electrically connecting the ITE-module and the BTE-module. The connecting part comprises at least two electric conductors connected to the rechargeable battery and to the ITE-module to allow provision of electric energy to the ITE-module. The BTE-module may comprise a wireless interface to another device.

Abstract: A hearing aid system configured to compensate for a hearing impairment of a use comprises A) a wearable device adapted for being worn by the user and comprising a1) an input stage comprising at least one input transducer for converting sound around the user to at least one electric input signal representing said sound, and a2) an input stage for providing stimuli representative of a processed version of said least one electric input signal to said user, said stimuli being perceivable by said user as sound; and B) a non-wearable device comprising b1) a processor, and b2) a power supply interface for providing power to the processor. The wearable device and the non-wearable device comprise respective transceiver circuitry for establishing a low latency wireless audio communication link between them. The processor of the non-wearable device comprises an audio processor configured to process said at least one electric input signal, or a signal originating therefrom, to at least partially compensate for the hearing impairment of the user and to provide said processed version thereof. The power supply interface of the non-wearable device is electrically connected to an electricity network. Thereby an improved processing power of a hearing aid may be provided. The invention may e.g. be used in flexible hearing aid systems with a situation-dependent configurable processing power.

Abstract: The invention relates to an audio assist system, comprising a hearing aid, an external handheld device and an audio system comprising a Bluetooth audio transmitter, wherein the hearing aid comprises a Bluetooth receiver. The hearing aid and the external handheld device are temporarily connected via a wireless data link, and both the audio system and the external handheld device each comprise an infrared receiver and/or transmitter for establishing an at least unidirectional IR link between the external handheld device and the audio system. The external handheld device is adapted to transmit an automatic Bluetooth pairing trigger signal to the hearing aid via the wireless data link, when the external handheld device receives and/or transmits an IR signal via the IR link from or to the audio system, respectively, and the hearing aid is configured to perform Bluetooth pairing with the Bluetooth audio transmitter in response to receiving the automatic Bluetooth pairing trigger signal from said external handheld device.

Abstract: An external microphone array is configured to be used with a hearing aid and comprises a number of microphones configured to detect one or more sound signals from a sound source and means for wirelessly sending the detected sound signal to at least one hearing aid. The external microphone array comprises means for automatically determining the direction of the sound source either by: a) receiving a wireless signal transmitted from a remote control; b) by receiving acoustic signals picked up by the hearing aid(s) and by further comparing the signals with signals received by the external microphone array. The external microphone array may e.g. take the form of a sphere, a hemi-sphere or a neckband.
