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.

Figure imgaf001
It is a hearing device with low feedback tendency while open supply and use of the natural directivity of the pinna are provided. For this purpose, it is provided to equip the hearing device with a tubular earmold (OP) for insertion into an auditory canal. In the earmold (OP) a loudspeaker (LS) is arranged. Furthermore, at least two microphones, which are arranged acoustically symmetrically to the loudspeaker (LS) in the earmold (OP) in the inserted state of the hearing device, are located in the earmold (OP). Thus, the sound emitted by the loudspeaker (LS) can be distinguished from the useful sound, so that the degree of feedback can be reduced. At the same time, the open supply and the utilization of the natural directivity of the pinna are guaranteed.
