Abstract: A binaural hearing system comprises first and second hearing aids, each comprising antenna and transceiver circuitry allowing the exchange of audio signals between them and a BTE-part adapted for being located at or behind the external ear (pinna) of the user and comprising front and rear input transducers providing respective front and rear electric input signals. Each 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. The inputs to the primary 2-channel beamformers are, locally generated, front and rear electric input signals. The inputs to the secondary 2-channel beamformer may be beamformed signals from the first and second hearing aids respectively. The spatially filtered signal of the secondary 2-channel beamformer may comprise an estimate of a target signal in the environment of the user.

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.

Abstract: The application relates to a binaural hearing assistance system comprising left and right hearing assistance devices, and a user interface, to its use and to a method. The left and right hearing assistance devices comprises a) at least two input units for providing a time-frequency representation of an input signal in a number of frequency bands and a number of time instances; and b) a multi-input unit noise reduction system comprising a multi-channel beamformer filtering unit operationally coupled to said at least two input units and configured to provide a beamformed signal. The binaural hearing assistance system is configured to allow a user to indicate a direction to or location of a target signal source relative to the user via said user interface. This has the advantage that interaural cues of the target signals can be maintained, while the ambient noise is reduced.
