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: The invention refers to a hearing aid system that comprises an electric audio signal input, an audio input signal processing unit that is configured to process electric audio input signals in the first processing mode or in the second processing mode and to provide an electric audio output signal, and an output transducer. The hearing aid system further comprises an audio input signal analysing unit that is configured to continuously monitor the electric audio input signal as a function of time and to determine and to provide a number of audio signal values each representing a characteristic of the electric audio input signal at a given time instance.The hearing aid system further comprises a plurality of electrodes that are configured to be brought into contact with the skin of a user and which are configured—when operationally mounted—to receive an electric signal that rep-resents a user's brain activity and to provide a respective EEG-related signal. The hearing aid system further comprises an EEG-related signal analysing unit that is configured to continuously monitor the EEG-related signal as a function of time and to determine and to provide a number of EEG-related values each representing the EEG-related signal at a given time instance, a memory unit which is configured to store a number of audio signal values such that a first history of respective audio signal values is created and/or to store a number of EEG-related values such that a second history of respective EEG-related values is created and a signal comparison unit that is configured to compare a current audio signal value with at least one preceding audio signal value of the first history to determine and to provide a deviation signal and/or to compare a current EEG-related value with at least one preceding EEG-related value of the second history to determine a measure of a user's current cognitive load and to provide a cognitive load representing output signal accordingly.The audio input signal processing unit is further configured to apply the first processing mode or the at least second processing mode depending on said deviation signal and/or depending on said cognitive load representing output signal

Abstract: The application relates to a portable electronic system comprising a first electronic device and an auxiliary device. The first electronic device comprises a first antenna defining a first spatial direction, and a first wireless unit operationally coupled to the first antenna. The auxiliary device comprises a second antenna defining a second spatial direction, the second antenna comprising a multitude of antenna elements, each defining a specific spatial direction, a second wireless unit operationally coupled to the second antenna, a direction detector configured to provide a direction-signal indicating an estimate of a current value of said second spatial direction relative to a reference direction, and a control unit configured to selectively control the connection of said multitude of antenna elements of the second antenna to said second wireless unit based on said direction-signal from the direction detector. Thereby a wireless link between a hearing assistance device and an auxiliary device can be optimized.
