Abstract

Die Signalverarbeitung einer Hörvorrichtung und insbesondere eines Hörgeräts soll besser der Situation angepasst werden können. Hierzu wird ein Verfahren zum Verarbeiten eines Eingangssignals (e) gemäß einem ersten Verarbeitungsalgorithmus (11) zu einem ersten Zwischensignal (a11) und Verarbeiten des Eingangssignals (e) gemäß einem zweiten Verarbeitungsalgorithmus (13) zu einem zweiten Zwischensignal (a13) parallel zu dem Verarbeiten des Eingangssignals (e) gemäß dem ersten Verarbeitungsalgorithmus (11) vorgeschlagen. Das Eingangssignal wird mit einem Klassifikator (14) klassifiziert. Schließlich wird ein Ausgangssignal (a) mit einem konstanten Mischverhältnis sowohl aus dem ersten als auch aus dem zweiten Zwischensignal (am. a13) unter Berücksichtigung des Ergebnisses des Klassifizierens gebildet. Damit können gleichzeitig die Vorteile mehrerer Algorithmen genutzt werden.

The signal processing of a hearing device and in particular a hearing aid should be able to be better adapted to the situation. For this purpose, a method for processing an input signal (e) according to a first processing algorithm (11) to a first intermediate signal (a 11 ) and processing the input signal (e) according to a second processing algorithm (13) to a second intermediate signal (a 13 ) in parallel to the processing of the input signal (e) according to the first processing algorithm (11) proposed. The input signal is classified with a classifier (14). Finally, an output signal (a) having a constant mixing ratio from both the first and second intermediate signals (am.a 13 ) is formed in consideration of the result of classifying. At the same time, the advantages of several algorithms can be used.
