Abstract

Die Erfindung betrifft ein Hörhilfesystem (100) mit mindestens zwei Hörhilfegeräten (110, 110') zur Anordnung an beiden Seiten eines Kopfes eines Trägers (201) sowie ein Verfahren zum Betrieb desselben. Die Hörhilfegeräte (110, 110') weisen einen Wandler (2, 2') zur Aufnahme eines akustischen Signals und Wandlung in ein jeweils erstes Audiosignal auf. Das Hörhilfesystem (100) weist weiterhin eine Signalverarbeitungsvorrichtung (3, 3') zur Verarbeitung von Audiosignalen und eine Signalverbindung (6) zur Übertragung eines ersten Audiosignals von jedem Hörhilfegerät (110, 110') zu der Signalverarbeitungseinrichtung (3, 3') auf. Die Signalverarbeitungsvorrichtung (3, 3') bewertet einen Signalanteil aus einer Vorzugsrichtung in Bezug auf den Kopf des Trägers (201) in den ersten Audiosignalen, wobei die Signalverarbeitungsvorrichtung (3, 3') mit den ersten Audiosignalen ein erstes binaurales direktionales Mikrofonsignal erzeugt, und stellt dessen Richtcharakteristik (220) in Abhängigkeit von der Bewertung ein.
