Abstract

Die Störgeräuschunterdrückung bei Hörervorrichtungen soll optimiert werden. Daher wird eine Hörervorrichtung, insbesondere ein Hörgerät (HG), vorgeschlagen, das eine Richtungsdetektionseinrichtung (RM)zum Detektieren einer Richtung, aus der von einer Schallquelle (Q) ein Schallsignal eintrifft, und eine Signalverarbeitungseinrichtung (VE) zum Verarbeiten des eintreffenden Schallsignals in Abhängigkeit von der detektierten Richtung aufweist. Eine Geräuschklassifikationseinrichtung (GK) zum Klassifizieren des von der Schallquelle (Q) eintreffenden Schallsignals in Signalklassen ermöglicht, dass das eintreffende Schallsignal auch in Abhängigkeit von der Signalklasse verarbeitet wird. Mit Hilfe eines Signalgenerators (SG) und eines Hörers (H) kann beispielsweise ein Hörgeräteträger über die Art und Richtung eines Geräusches informiert werden, das andernfalls durch die Störgeräuschunterdrückung so stark gedämpft würde, dass das Geräusch für ihn nicht mehr wahrnehmbar wäre.

The noise suppression in handset devices should be optimized. Therefore, a hearing device, in particular a hearing aid (HG) is proposed, which comprises a direction detection device (RM) for detecting a direction from which a sound signal from a sound source (Q) arrives, and a signal processing device (VE) for processing the incoming sound signal in dependence from the detected direction. A noise classification device (GK) for classifying the sound signal arriving from the sound source (Q) into signal classes makes it possible for the incoming sound signal to also be processed as a function of the signal class. With the aid of a signal generator (SG) and a receiver (H), for example, a hearing aid wearer can be informed about the type and direction of a noise that would otherwise be so strongly attenuated by the noise suppression that the noise would no longer be perceptible to him.
