Abstract

Die Erfindung gibt ein Hörgerät (1) mit einer Rückkopplungsunterdrückungseinheit (17) und ein zugehöriges Verfahren an.
Das Hörgerät umfasst des Weiteren ein durch eine erste Grenzfrequenz (GF1) charakterisiertes Tiefpassfilter (18), das aus einem Ausgangssignal (103) des Hörgeräts (1) einen niederfrequenten Signalanteil (105) auskoppelt, ein durch eine zweite Grenzfrequenz (GF2) charakterisiertes Hochpassfilter (19), das aus dem Ausgangssignal (103) des Hörgeräts (1) einen hochfrequenten Signalanteil (104) auskoppelt, eine Frequenzverschiebeeinheit (20), welche die Frequenz (F) des hochfrequenten Signalanteils (104) zu höheren Frequenzen verschiebt.
Zwischen der ersten und der zweiten Grenzfrequenz (GF1, GF2) besteht eine Lücke. Infolge der unterschiedlichen Grenzfrequenzen (GF1, GF2) werden durch Frequenzverschiebung verursachte Signalverzerrungen effektiv unterdrückt. Eine Rückkopplungsunterdrückung erfolgt bei höheren Frequenzen kontinuierlich und schnell.
