Abstract

Psychoakustische Randbedingungen sollen bei der Verstärkung von Eingangssignalen einer Hörvorrichtung besser berücksichtigt werden. Dazu wird ein Verfahren zum Verstärken eines Eingangssignals in einer Hörvorrichtung durch Vorgeben je einer kanalspezifischen Kompressionskennlinie (12) in mehreren spektral getrennten Verarbeitungskanälen der Hörvorrichtung, die einen Zusammenhang zwischen einem Eingangspegel (LE) und einem Ausgangspegel (LA) im jeweiligen Verarbeitungskanal der Hörvorrichtung definiert, und Verstärken eines jeweiligen Eingangssignalanteils der Hörvorrichtung in jedem Verarbeitungskanal in Abhängigkeit von einer kanalspezifischen Betriebs-Kompressionskennlinie (10) vorgeschlagen. Dabei wird eine kanalspezifische Eingangspegelschwelle (LS) für jeden Verarbeitungskanal vorgegeben. Anschließend erfolgt ein Festlegen der jeweiligen kanalspezifischen Betriebs-Kompressionskennlinie (10) entsprechend der vorgegebenen kanalspezifischen Kompressionskennlinie (12) unterhalb der kanalspezifischen Eingangspegelschwelle (LS) und ein Festlegen des jeweiligen Verlaufs der kanalspezifischen Betriebs-Kompressionskennlinie (10) mit einem Kompressionsverhältnis größer 8 oberhalb der kanalspezifischen Eingangspegelschwelle (LS).
