Abstract (de)

Bei einem Hörgerät mit einem Ohrpassstück (20; 30) ist ein Schallaustritt (18) für den verstärkten Schall vorgesehen. Zur Vermeidung eines Okklusionseffekts weist das Ohrpassstück ein Venting (36; 38) auf. Das Venting ist mit einem frequenzabhängigen Schalldämpfungselement (50; 60, 70; 80; 90; 100) versehen, derart dass eine Rückkopplung von höherfrequentem Schall vermieden wird. <IMAGE>
