Abstract

Die Erfindung gibt Anordnungen und zugehörige Verfahren zur Erkennung (22) von akustischen Rückkopplungen bei einer Hörvorrichtung (1) an. Eine Ausführungsform umfasst eine erste Rückkopplungserkennungseinheit (61), die eine Rückkopplungswahrscheinlichkeit (16) ermittelt, eine zweite Rückkopplungserkennungseinheit (62), die einen Gewichtungsfaktor (17) ermittelt, und eine Recheneinheit (63), die die Rückkopplungswahrscheinlichkeit (16) mit dem Gewichtungsfaktor (17) multipliziert. Alternativ zum Ermitteln des Gewichtungsfaktors (17) kann auch ein Schwellwert (20) geregelt werden. Die Erfindung bietet den Vorteil der Verbesserung einer akustischen Rückkopplungserkennung (22) durch eine Kombination zweier unterschiedlicher Rückkopplungserkennungsverfahren (61, 62).
