    Abstract: A hearing device comprises an ITE-part adapted for being located at or in an ear canal of the user comprising a housing comprising a seal towards walls or the ear canal, the ITE part comprising at least two microphones located outside the seal and facing the environment, and at least one microphone located inside the seal and facing the ear drum. The hearing device may comprise a beamformer filter connected to said at least three microphones comprising a first beamformer for spatial filtering said sound in the environment based on input signals from said at least two microphones facing the environment, and a second beamformer for spatial filtering sound reflected from the ear drum based on said at least one electric input signal from said at least one microphone facing the ear drum and at least one of said input signals from said at least two microphones facing the environment.

    Abstract: A hearing device, e.g. a hearing aid, comprises a) a multitude of input transducers for providing respective electric input signals representing sound in an environment of the user; b) an output transducer for providing stimuli perceivable to the user as sound based on said electric input signals or a processed version thereof; c) an adaptive beamformer filtering unit connected to said input unit and to said output unit, and configured to provide a spatially filtered signal based on said multitude of electric input signals and adaptively updated beamformer weights; and d) a feedback estimation unit providing feedback estimates of current feedback paths from said output transducer to each of said input transducers. The hearing device is configured to provide that at least one of said adaptively updated beamformer weights of the adaptive beamformer filtering unit is/are updated in dependence of said feedback path estimates. The application further relates to a method of suppressing feedback.

    Abstract: A hearing device comprising a first and a second input sound transducers, a processing unit, and an output sound transducer. The first transducer is configured to be arranged in an ear canal or in the ear of the user, to receive acoustical sound signals from the environment and to generate first electrical acoustic signals from the received acoustical sound signals. The second transducer is configured to be arranged behind a pinna or on, behind or at the ear of the user, to receive acoustical sound signals from the environment and to generate second electrical acoustic signals from the received acoustical sound signals. The processing unit is configured to process the first and second electrical acoustic signals and apply a direction dependent gain. The output sound transducer is configured generate acoustical output sound signals in accordance with the applied direction dependent gain.
