Abstract

Ein Hörgerät soll zweckbestimmt angewendet werden können, ohne dass es als Ganzes oder sein Hörmodul zur Vermeidung akustischer Rückkopplung zum Mikrophon des Systems hin bzw. zur akustischen Entkopplung in den Gehörgang ausreichend schalldicht und deswegen mit Hautkontakt eingesetzt werden müssen, sondern vor dem Eingang des Gehörgangs getragen werden können.A hearing aid should be able to be used in a purposeful manner, without it having to be used soundly and therefore with skin contact as a whole or its hearing module to avoid acoustic feedback to the microphone of the system or for acoustic decoupling in the ear canal, but worn in front of the entrance of the ear canal can be.

Das Hörgerät (1) nutzt hierfür den Effekt der Bildung von Kombinationstönen aus zwei unterschiedlichen Tönen innerhalb des Ohres selbst aufgrund des von diesem dargestellten Übertragungssystems mit nichtlinearen Übertragungseigenschaften, von welchen Tönen der Differenzton, also der Ton mit der Differenzfrequenz, am stärksten auftritt. Hierzu werden die von dem im Gehäuse (2) des Hörgerätes (1) an der Stelle (3) befindlichen Mikrophon aufgenommenen und in elektrische Signale gewandelten Schallsignale nach einer dem Hördefizit des Hörgeräteträgers gemäßen Signalverarbeitung mittels einer Trägerfrequenz in einen Frequenzbereich oberhalb des Hörbarkeitsbereiches transponiert und zusammen mit der Trägerfrequenzschwingung nach der Wandlung durch den an einer anderen Stelle (4) befindlichen Schallstrahler in akustische Signale (6") dem Ohr zugeführt, in welchem durch den Effekt der Differenztonbildung die Transposition wieder rückgängig gemacht wird, und so das anwendungsgemäß verarbeitete Schallsignal wieder im hörbaren Frequenzbereich zur Verfügung steht.

Figure imgaf001
The hearing aid (1) uses for this purpose the effect of the formation of combination sounds of two different tones within the ear itself due to the transmission system shown by this with non-linear transmission characteristics, of which tones the difference tone, ie the sound with the difference frequency, the strongest occurs. For this purpose, the sound signals recorded by the microphone (2) of the hearing aid (1) at the location (3) and converted into electrical signals are transposed into a frequency range above the audibility range by means of a carrier frequency in accordance with a hearing aid wearer's hearing deficit with the carrier frequency oscillation after the conversion by the sound emitter located at another location (4) into acoustic signals (6 ") supplied to the ear, in which the transposition is canceled again by the effect of difference tone formation, and so again the sound signal processed according to the application audible frequency range is available.
