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 detects whether an ear mould of a listening device is correctly mounted in the ear of a user. An indication of whether or not a mould of a listening device is correctly mounted in an ear canal of a user is provided. The method comprises a) providing a long term estimate of the feedback path; b) providing an estimate of the current feedback path; c) comparing the long term feedback path estimate with the current feedback path estimate, and providing a measure of their difference, termed the feedback difference measure FBDM; and optionally d) providing an alarm indication, if the feedback difference measure exceeds a predefined threshold.

    Abstract: The application relates to a hearing assistance device and to a method of performing a real ear measurement. The method comprises providing a first controlled acoustic feedback path from an output transducer to a measurement input transducer via a standard acoustic coupler; generating a first probe signal; estimating and storing a first estimate of the first controlled acoustic feedback path; and providing a second controlled acoustic feedback path from the output transducer to the measurement input transducer via the residual volume between the ITE part of the hearing aid device and the user's eardrum; generating a second probe signal; estimating and storing a second estimate of the second controlled acoustic feedback path; and determining a real ear to coupler difference from said first and second acoustic feedback estimates. An alternative and relatively simple method of determining an RECD-value in hearing assistance device of a particular user is thereby provided.

    Abstract: A hearing aid adapted for being worn by a user at or in an ear of the user comprises a) at least one input transducer for converting sound in an environment around the user to at least one electric input signal representing said sound; b) an output transducer for converting a processed output signal provided in dependence of said at least one electric input signal to stimuli perceivable to the user as sound; c) a feedback control system comprising an adaptive filer, the feedback control system being configured to provide an adaptively determined estimate (h*(n)) of a current feedback path (h(n)) from said output transducer to said at least one input transducer in dependence of c1) said at least one electric input signal, c2) said processed output signal, and c3) an adaptive algorithm. The hearing aid further comprises d) a database comprising a multitude (M) of previously determined candidate feedback paths (hm); and e) a controller configured to identify a change in the current feedback path (h(n)) based on the adaptively determined estimate (h*(n)) of the current feedback path and at least one of said multitude of previously determined candidate feedback paths (hm). A method of operating a hearing aid is further disclosed. The invention may e.g. be used in hearing aids, e.g. binaural hearing aid systems or headsets, or speakerphones, or combinations thereof.
