1. A listening instrument adapted for being worn by a user and comprising,a) a microphone unit for picking up an input sound from the current acoustic environment of the user and converting it to an electric microphone signal;

  • b) a microphone gain unit for applying a specific microphone gain to the electric microphone signal and providing a modified microphone signal;

    c) a direct electric input signal representing an audio signal;

    d) a direct gain unit for applying a specific direct gain to the direct electric input signal and providing a modified direct electric input signal;

    e) a detector unit for classifying the current acoustic environment of the user and providing one or more classification parameters;

    f) a control unit for controlling the specific microphone gain applied to the electric microphone signal and/or the specific direct gain applied to the direct electric input signal based on the one or more classification parameters;

    wherein the detector unit comprises an own-voice detector (OVD) for determining whether or not the user is speaking at a given point in time.
