Abstract: The problem of estimating the direction to one or more sound sources of interest relative to a user wearing a pair of hearing devices, e.g. hearing aids, is dealt with. A target signal is generated by a target signal source and transmitted through an acoustic channel to a microphone of a hearing system. Due to 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 transmitted to the hearing devices of the hearing system via a wireless connection. Each of the hearing devices comprises a signal processing unit comprising a sound propagation model of the acoustic propagation channel from the target sound source to the hearing device when worn by the user. The sound propagation model is configured to be used for estimating a direction-of-arrival of the target sound signal relative to the user.

The application further relates to a method of operating a binaural hearing assistance system. The object of the present application is to provide an improved binaural hearing assistance system. The problem is solved in that each of the first and second hearing assistance devices comprises a) a first wireless interface comprising first antenna and transceiver circuitry adapted for establishing a first communication link to the respective other hearing assistance device based on near-field communication; b) a second wireless interface comprising second antenna and transceiver circuitry adapted for establishing a second communication link to an auxiliary device based on far-field communication; c) a link control unit operatively coupled to the second antenna and transceiver circuitry and configured to repeatedly provide a second link quality measure indicative of a link quality of the second communication link; wherein the first and second hearing assistance devices are configured to exchange said respective second link quality measures between them via said first and/or second communication links. This has the advantage of providing a robust and flexible system. The invention may e.g. be used for binaural hearing assistance systems, e.g. binaural hearing aid systems, where audio quality and power consumption has to be mutually optimized.
