Abstract (en)
The device has a tone generator e.g. sinus-wave generator, generating a continuous tone for a sound signal with a constant frequency of 2-10 kiloHertz set to adjust the hearing device to a hearing-device wearer. The tone generator comprises a switching element that generates an electrical voltage with a characteristic time response. An electro-acoustic output converter e.g. micro-loudspeaker, outputs the continuous tone to the hearing-device wearer. An electroacoustic input converter e.g. microphone, receives the sound signal that is amplified by an amplifying unit. An independent claim is also included for a method for operating a hearing device.
Abstract (de)
Die Erfindung betrifft ein Hörgerät, aufweisend einen elektroakustischen Ausgangswandler, dadurch gekennzeichnet, dass das Hörgerät einen Tongenerator zur Erzeugung eines Dauertons mit konstanter Frequenz aufweist. Durch Erzeugen des Dauertons können im Innenohr über nicht-lineare Transformationsprozesse Hochtonfrequenzen in hörbare Bereiche transformiert werden.
