    Abstract: A hearing system configured to be located at or in the head of a user, comprises a) at least two microphones providing at least two electric input signals, b) an own voice detector, c) access to a database (Ol, Hl) comprising c1) relative or absolute own voice transfer function(s), and corresponding c2) absolute or relative acoustic transfer functions for a multitude of test-persons, d) a processor connectable to the at least two microphones, to the own voice detector, and to the database. The processor is configured A) to estimate an own voice relative transfer function for sound from the user's mouth to at least one of the at least two microphones, and B) to estimate personalized relative or absolute head related acoustic transfer functions from at least one spatial location other than the user's mouth to at least one of the microphones of the hearing system in dependence of the estimated own voice relative transfer function(s) and the database (Ol, Hl). The hearing system further comprises e) a beamformer configured to receive the at least two electric input signals, or processed versions thereof, and to determine personalized beamformer weights based on the personalized relative or absolute head related acoustic transfer functions or impulse responses. A method of determining personalized beamformer coefficients (wk) is further disclosed.

    Abstract: A hearing device, e.g. a hearing aid, comprises a) an input unit comprising a1) at least one first input transducer for picking up said sound user and providing respective at least one first electric input signals, and a2) a second input transducer for picking up said sound and providing a second electric input signal, the second input transducer being located at or in an ear canal of the user; b) an output unit comprising an output transducer for converting a processed electric signal representing said sound to a stimulus perceivable by said user as sound; c) a near-field beamformer applied to said multitude of electric input signals and implementing a feedback suppression system for suppressing feedback from said output unit to said at least one first input transducer, and comprising an adaptation unit for modifying the second electric input signal in approximation of an acoustic transfer function, or an impulse response, from the second input transducer to the at least one first input transducer and providing a modified second electric input signal representative of an estimate of said feedback. This has the advantage of allowing an increased gain to be applied to the input sound signal without a risk of feedback. A method of operating a hearing device is furthermore provided.

    Abstract: The application relates to a hearing device comprising a) first and second input transducers for picking up sound signals from the environment and providing first and second electric input signals, b) a first and signal strength detectors for providing signal strength estimates of the first and second electric input signal, the first input transducer being located at or behind an ear of the user, and the second input transducer being located at or in an ear canal of the user. The hearing device further comprises c) a signal processing unit providing a processed signal based on the first and second electric input signals, and d) an output unit comprising an output transducer for converting the processed signal or a signal originating therefrom to a stimulus perceivable by said user as sound. The hearing device further comprises e) a feedback detector comprising e1) a comparison unit operationally coupled to the first and second signal strength detectors and configured to compare the signal strength estimates of the first and second electric input signals and to provide a signal strength comparison measure indicative of the difference between the signal strength estimates, and e2) a decision unit for providing a feedback measure indicative of current acoustic feedback from the output transducer to the first and/or second input transducers based on the comparison measure. In an embodiment, the feedback measure is used to control processing in the signal processing unit, e.g. a beamformer unit and/or a feedback cancellation system, and/or an amplification unit. The invention may e.g. be used in hearing aids, in particular hearing aids comprising an ITE-part adapted for being located at or in an ear canal of a user and a BTE-part adapted for being located at or behind an ear or the user.

    Abstract: A hearing aid device is disclosed. The hearing aid device comprises a receiver configured to be arranged in the ear canal. The hearing aid device comprises a directional microphone system comprising two microphones or one microphone having two sound inlets. The hearing aid device comprises means for counteracting acoustic feedback on the basis of sound signals detected by the two microphones or the two sound inlets. The hearing aid device comprises an “open fitting” providing ventilation. The two microphones or the two sound inlets of the directional microphone (forming part of a directional system) are arranged in the ear canal at the same side of the receiver and sound is allowed to propagate freely between the microphones or between the inlets of the directional microphone and the receiver. Preferably, the hearing aid device comprises a procedure (such as an adaptive procedure) for optimizing the directional system of the hearing aid device. An improved feedback reduction is thereby achieved, while allowing a relatively large gain to be applied to the incoming signal.
