    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.

    Abstract: A method of estimating a real-ear-to-coupler-difference (RECD) in a hearing is provided. The hearing aid comprises an input transducer; an output transducer; and an ITE-part configured to define a residual volume when mounted in an ear canal of a user. The method comprises providing an earpiece configured to fit tightly to walls of an ear canal of the user and to provide said residual volume; that the earpiece comprises at least one ventilation channel or opening; a sound outlet allowing sound from said output transducer to be played into said residual volume; characteristics of the at least one ventilation channel or opening; a frequency dependent feedback path estimate from said output transducer to said input transducer through said ventilation channel or opening; and estimating a low-frequency and high frequency RECD values in dependence said feedback path estimate; and determining estimated frequency dependent RECD values in dependence of said estimated low-frequency RECD value, and said estimated high-frequency RECD value.

    Abstract: A hearing aid comprises a forward path comprising a) at least two input transducers, each for picking up sound from the environment of the hearing aid and providing respective at least two electric input signals; b) a beamformer filter for filtering said at least two electric input signals or signals originating therefrom and providing a spatially filtered signal; c) a signal processor for processing one or more of said electric input signals or one or more signals originating therefrom, and providing one or more processed signals based thereon; and d) an output transducer for generating stimuli perceivable by the user as sound based on said one or more processed signals. The hearing aid further comprises e) a feedback estimation system for estimating a current feedback from the output transducer to each of the at least two input transducers and providing respective feedback measures indicative thereof; and f) a controller configured to receive said feedback measures from said feedback estimation system and to switch between two modes of operation of the hearing aid, a one-input transducer (e.g. omni-directional) mode of operation, and a multi-input transducer (directional) mode of operation, in dependence of the feedback measures. to. The application further relates to a method of operating a hearing aid. Thereby the gain provided by the hearing aid to the user (without a significant risk of howl) can be maximized.

    Abstract: The application relates to a hearing device comprising an ITE-part adapted for being located at or in an ear canal of a user, a configurable signal processing unit for processing an input signal, and a feedback estimation unit for providing a current estimate of an acoustic feedback path from an output transducer to an input transducer, a memory for storing frequency dependent reference estimates of the acoustic feedback path the real ear to coupler difference, when the ITE-part is correctly mounted, an optional probe signal generator for generating a probe signal at least in a specific measurement mode, wherein the hearing device is configured to perform measurement of the current estimate of the acoustic feedback path. The hearing device further comprises a control unit operatively connected to said memory and to said signal processing unit, and configured to compare said current estimate of the acoustic feedback path with said reference estimate of the acoustic feedback path, and to provide a current feedback path difference measure, and to determine a current estimate of real ear to coupler difference from the current feedback path difference measure. This has the advantage facilitating the mounting of the ear ITE-part. The invention may e.g. be used in hearing aids for compensating a user's hearing impairment.
