    Abstract: Disclosed herein are embodiments of a hearing aid configured to be worn by a user at or in an ear of the user and having an ITE-part adapted for being located at or in an ear canal of the user. The hearing aid can include an active occlusion cancellation system (AOCS) for providing an acoustic anti-occlusion signal configured to cancel or diminish a sense of occlusion of the user when the user is speaking, or otherwise is using his or her voice, or when otherwise moving the jaws. Methods of operating a hearing aid are further disclosed.

    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, configured to be worn by a user, comprises a) two or more input transducers (e.g. microphones) wherein said two or more input transducers during use of the hearing device are arranged with a distance between them; b) a directional system comprising a directional algorithm configured to provide a directional pattern in dependence of said distance. The hearing device is configured to estimate a current value of said distance, or an equivalent acoustic delay, or beamformer weights of said directional system, thereby the directional performance can be optimized to the individual user.

    Abstract: The application relates to a hearing device, e.g. a hearing aid, adapted for being arranged at least partly on a user's head or at least partly implanted in a user's head. The hearing device comprises a) an input unit comprising first and second input transducers for picking up sound from the environment of the user and providing first and second electric input signals, the first and second input transducers being located on the head, (e.g. at or behind an ear) and at or in an ear canal of the user, respectively, b) a signal processing unit providing a processed signal based on one or more of said multitude of electric input signals, and c) an output unit comprising an output transducer for converting said processed signal or a signal originating therefrom to a stimulus perceivable by said user as sound. The hearing device further comprises an own voice detector comprising first and second signal strength detectors for providing signal strength estimates of the first and second electric input signals. The own voice detector comprises 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 said signal strength estimates; and a control unit for providing an own voice detection signal indicative of a user's own voice being present or not present in the current sound in the environment of the user, the own voice detection signal being dependent on said signal strength comparison measure. Thereby an alternative scheme for detecting a user's own voice is provided. The invention may e.g. be used for the hearing aids, headsets, active ear protection systems, etc.
