Abstract

Durch die getaktete Arbeitsweise gehen von digitalen Hörhilfegeräten oder Hörgerätesystemen elektromagnetische Störsignale mit der Taktfrequenz und deren Harmonische aus. Diese können die drahtlose Signalübertragung zwischen dem Hörhilfegerät oder Hörgerätesystem und einem weiteren Gerät stören. Zur Vermeidung dieser Störungen sieht die Erfindung eine Jitter-Einheit (14) vor, die mit dem Taktgenerator (6) verbunden ist und Frequenzschwankungen bei dem Taktsignal verursacht. Dadurch werden die durch das Taktsignal verursachten Störsignale in ihren Amplituden abgesenkt, womit eine störungsfreie Signalübertragung zwischen einer mit dem Hörhilfegerät verbundenen Sende- und/oder Empfangseinheit (12) und einem externen Gerät ermöglicht wird.
