Abstract

Die Feedbackkompensation bei Hörgeräten soll verbessert werden. Hierzu wird der Kompensationsumfang gesteuert. Ein Schätzsignal wird gewonnen, mit dem die Intensität des Rückkopplungssignals geschätzt wird. Die Dämpfung des Rück-kopplungssignals läßt sich somit anhand des Schätzsignals steuern. Damit ist es beispielsweise möglich, die Feedbackkompensation bei nicht vorhandener Rückkopplung abzuschalten, so dass Artefakte vermieden werden können.
