Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb eines Hörhilfesystems (100) sowie ein Hörhilfesystem (100) mit wenigstens zwei Hörhilfegeräten (110, 110'), zwischen denen ein Signalpfad vorgesehen ist, und mit wenigstens einer Signalverarbeitungseinheit (3, 3'), die zur Verarbeitung von Audiosignalen vorgesehen ist. In dem erfindungsgemäßen Verfahren filtert die Signalverarbeitungsvorrichtung (3, 3') erste Audiosignale mit einem für eine gegebene Raumrichtung, aus der ein Nutzsignal eintrifft, vorbestimmten Filter (31, 31'), sodass zweite Audiosignale erzeugt werden, in denen die Anteile des Nutzsignals in den zweiten Audiosignalen in einem höheren Maß aneinander angeglichen sind als in den ersten Audiosignalen. Anschließend werden die zweiten Audiosignale mit einem adaptiven Filter (32, 32') gefiltert, sodass dritte Audiosignale erzeugt werden, in denen die Anteile des Nutzsignals in einem noch höheren Maß aneinander angeglichen sind als in den zweiten Audiosignalen.
