Abstract

Es soll eine Hörvorrichtung mit geringer Rückkopplungsneigung bei gleichzeitig offener Versorgung und Ausnutzung der natürlichen Richtwirkung der Pinna bereitgestellt werden. Dazu ist vorgesehen, die Hörvorrichtung mit einem rohrförmigen Ohrpassstück (OP) zum Einsetzen in einen Gehörgang auszustatten. In dem Ohrpassstück (OP) ist ein Lautsprecher (LS) angeordnet. Weiterhin befinden sich in dem Ohrpassstück (OP) mindestens zwei Mikrofone, die im eingesetzten Zustand der Hörvorrichtung in dem Ohrpassstück (OP) akustisch symmetrisch zu dem Lautsprecher (LS) angeordnet sind. Damit lässt sich der von dem Lautsprecher (LS) abgestrahlte Schall von dem Nutzschall unterscheiden, so dass der Rückkopplungsgrad reduziert werden kann. Gleichzeitig ist dabei die offene Versorgung und die Ausnutzung der natürlichen Richtwirkung der Pinna gewährleistet.
