Hearing device comprising a microphone adapted to be located at or in the ear canal of a user

A hearing device 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 comprising

• an input unit for providing a multitude of electric input signals representing sound in an environment of the user, the input unit comprising
• at least one first input transducer for picking up said sound and providing respective at least one first electric input signals, the at least one first input transducer being located at a first location away from an ear canal of the user;
• 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;
• 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, and
• a near-field beamformer applied to said at least one first and said second 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,
• wherein said feedback suppression system comprises a filter for providing a filtered modified second electric input signal representative of an estimate of said feedback.

• a beamformer filtering unit providing a far-field beamformed signal based on at least two of said multitude of electric input signals or signals derived therefrom,
• wherein said beamformer filtering unit receives a possibly low pass filtered version of the second electric input signal, so that the beamformed signal is based on a combination of said at least one first electric input signal(s) and said second, low pass filtered, electric input signal.

A method of operating a hearing device adapted for being arranged at least partly on a user's head or at least partly implanted in a user's head, the method comprising

• providing a multitude of electric input signals representing sound, including
• picking up a sound signal from the environment at a first location away from an ear canal of the user and providing at least one first electric input signal,
• picking up a sound signal from the environment at a second location at or in said ear canal of the user and providing a second electric input signal, and
• modifying the second electric input signal in approximation of an acoustic transfer function or an impulse response for sound from said ear canal to said location away from said ear canal, and providing a modified second electric input signal,
• providing a feedback corrected signal based on said modified second electric input signal and on said at least one electric input signal, or a signal originating therefrom;
• and
• converting said feedback corrected signal or a processed version thereof to a stimulus perceivable by said user as sound,
• wherein the second electric input signal is delayed corresponding to a delay of an acoustic propagation path of sound from the second to the at least one first input transducer.
