Abstract

Die Adaptierung der Signalverarbeitung zur aktiven Okklusionsreduktion bei Hörvorrichtungen und insbesondere bei Hörgeräten soll weiter automatisiert werden. Dazu wird vorgeschlagen, eine Wandlerfunktion (RVM), die definiert ist für die Übertragungsstrecke (19) vom Eingang eines Hörers (16) über den Gehörgang (11, 13) zum Ausgang eines Mikrofons (17), einer automatischen Plausibilitätsprüfung zu unterziehen. Ein einstellbares Filter (18) über das das Mikrofonsignal rückgekoppelt wird, wird nur verändert, wenn die Wandlerübertragungsfunktion gemäß einem vorgegebenen Kriterium plausibel ist. Hierdurch können ungünstige Konvergenzen des Adaptionsalgorithmus vermieden und unnötig hohe Rechenzeiten verhindert werden.

The adaptation of the signal processing for active occlusion reduction in hearing devices and in particular in hearing aids should be further automated. For this purpose, it is proposed to subject a converter function (RVM), which is defined for the transmission path (19) from the input of a receiver (16) via the auditory canal (11, 13) to the output of a microphone (17), to an automatic plausibility check. An adjustable filter (18) over which the microphone signal is fed back, is only changed if the transformer transfer function is plausible according to a predetermined criterion. As a result, unfavorable convergence of the adaptation algorithm can be avoided and unnecessarily high computation times can be prevented.
