Abstract

Mit dem Verfahren werden akustische Signale bspw. in Hörgeräten auf eine solche Weise lautheitsgesteuert verarbeitet, dass die vom Hörbehinderten subjektiv empfundene Lautheit wieder stets der von Normalhörenden empfundenen Lautheit entspricht. Die Signalverarbeitung erfolgt ohne Fouriertransformation und ohne Aufteilung des Signals in Teilbandsignale auf iterative Weise vollständig im Zeitbereich. Damit wird der Nachteil inakzeptabel langer Signalverzögerungszeiten bekannter Verfahren eliminiert und eine praktische Nutzung überhaupt erst ermöglicht. Die Vorrichtung zur Durchführung des Verfahrens enthält eine Verarbeitungsstufe (4) zur iterativen Berechnung einer für die Lautheit charakteristischen Steuergrösse (ψ) und eine damit zeitabhängig gesteuerte Korrekturfilterstufe (7). Das erfindungsgemässe Verfahren erfordert gegenüber bekannten Verfahren nur drastisch reduzierte Verarbeitungsressourcen, was hauptsächlich auf die besonders effiziente und unkonventionelle Ausführung der Verarbeitungsstufen zurückzuführen ist.

With the method, acoustic signals are, for example, processed in a manner controlled by sound in hearing aids in such a way that the loudness subjectively perceived by the hearing impaired again always corresponds to the loudness perceived by normal hearing persons. The signal processing takes place without Fourier transformation and without dividing the signal into subband signals in an iterative manner completely in the time domain. This eliminates the disadvantage of unacceptably long signal delay times of known methods and makes practical use possible in the first place. The device for carrying out the method comprises a processing stage (4) for the iterative calculation of a loudness characteristic control variable (ψ) and thus a time-dependent controlled correction filter stage (7). The inventive method requires only drastically reduced processing resources compared to known methods, which is mainly due to the particularly efficient and unconventional execution of the processing stages.
