Abstract

Verfahren zur Elimination von Störsignalanteilen (SS) in einem Eingangssignal (ES), wobei das Verfahren darin besteht, das in einer Signalanalysephase (I) die Störsignalanteile (SS) und ein im Eingangssignal (ES) enthaltenes Nutzsignal (NS) charakterisiert werden und dass in einer Signalverarbeitungsphase (II) aufgrund der in der Signalanalysephase (I) erhaltenen Charakterisierung das Nutzsignal (NS) bzw. ein geschätztes Nutzsignal (NS') ermittelt bzw. erzeugt wird, wobei die Charakterisierung der Signalanteile (SS, NS) zumindest unter Verwendung von auditorisch-basierten Merkmalen (M1 bis Mj) erfolgt. Des weiteren ist eine Anwendung des erfindungsgemässen Verfahrens und ein Hörgerät, das nach dem erfindungsgemässen Verfahren arbeitet, angegeben.
