Abstract

Nebenläufige Signalpfade am Hörgerät vorbei bewirken Störungen im Ohrkanal. Diese Störungen werden durch Schätzen eines Störsignals (n̂) aus dem gestörten Eingangssignal (x) von einem Mikrofon (2) und Beaufschlagen des Störsignals (n̂) mit einer Übertragungsfunktion (Ĥ), mit der der nebenläufige akustische Signalpfad nachgebildet wird, unter Bildung eines Störausgangssignals (n̂Ĥ) sowie Verknüpfen eines Nutzausgangssignals von einer Signalverarbeitungseinrichtung (1) mit dem Störausgangssignal (n̂Ĥ) kompensiert. Damit kann eine Störunterdrückung durch Richtmikrofonverschaltungen auch dann ermöglicht werden, wenn nebenläufige Signalpfade dies bei herkömmlichen Ansätzen nicht ermöglichen.
