    Abstract: The present disclosure regards a hearing device comprising a power source, electric circuitry, a loudspeaker, at least one microphone for sound from an acoustic environment, and at least one wireless receiver for wirelessly received sound signals. The microphone is configured to generate an environment sound signal. The wireless receiver is configured generate a source sound signal. The electric circuitry is configured to estimate at least one parameter of an impulse response from the location of the origin of the wirelessly received signal to the location of a user of the hearing device in dependence on the source sound signal and the environment sound signal. The electric circuitry is further configured to process the environment sound signal in dependence on the estimated at least one impulse-response parameter, thereby generating an output sound signal. The output sound signal is processed into sound by the loudspeaker.

    Abstract: The application relates to a method of reducing reverberation in an audio processing device and to an audio processing device. The object of the present application is to provide an alternative method of reducing noise, e.g. reverberation, in a sound signal. The method comprises the steps of a) providing a time variant electric input signal representative of a sound; b) providing a logarithmic representation of said electric input signal; c) providing a predefined statistical model of the likelihood that a specific slope of the logarithmic representation of the electric input signal is due to reverberation; d) identifying time instances of the electric input signal being reverberant according to the statistical model; and e) applying an attenuation to the time instances identified as reverberant. This has the advantage of providing an enhanced sound signal. The invention may e.g. be used for enhancing noisy, e.g. reverberant, signals.

    Abstract: A hearing aid system comprising a pair of hearing devices, e.g. hearing aids, worn at the ears of a user receives a target signal generated by a target signal source and transmitted through an acoustic channel to microphones of the hearing aid system. Due to (potential) additive environmental noise, a noisy acoustic signal is received at the microphones of the hearing system. An essentially noise-free version of the target signal is simultaneously transmitted to the hearing devices of the hearing system via a wireless connection. Based on a sound propagation model of the acoustic propagation channel from the target sound source to the microphones of the hearing aid system, and on relative transfer functions representing direction-dependent filtering effects of the head and torso of the user in the form of direction-dependent acoustic transfer functions from a microphone on one side of the head, to a microphone on the other side of the head, a direction-of-arrival (DoA) of the target sound signal relative to the user is determined using a maximum likelihood approach.

    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.
