Abstract (en)

The system has two hearing aid devices (1, 11) with microphones (2, 12), signal processing units (3, 13) and headsets (4, 14). Transmission-and-control units (5, 15) and transmitting-and-receiving coils (7, 17) are provided for wireless signal transmission between the aid devices. The aid devices exhibit respective sensor units for detecting an outer magnetic field. One aid device is automatically switched into an operating mode when one sensor unit detects the magnetic field. Both the aid devices are switched-off when the sensor units simultaneously detect the magnetic field. An independent claim is also included for a method for operating a hearing aid device system.

Abstract (de)

Bei einem Hörhilfegerätesystem mit zwei am Kopf tragbaren Hörhilfegeräten (1, 11) soll sowohl ein automatisches Erkennen der Hörsituation "Telefonieren" als auch ein automatisches Abschalten der Hörhilfegeräte (1, 11) für den Fall, dass diese vom Kopf genommen werden, realisiert werden. Erfindungsgemäß umfassen die Hörhilfegeräte (1, 11) hierfür Sensoreinrichtungen (6, 16) mittels derer erkannt wird, ob sich das betreffende Hörhilfegerät (1, 11) in einem Magnetfeld, das eine bestimmte Feldstärke überschreitet, befindet. Durch Mittel zur drahtlosen Signalübertragung (5, 7; 15, 17) lassen sich diesbezügliche Daten zwischen den Hörhilfegeräten (1, 11) austauschen. Wird nur von einem der beiden Hörhilfegeräte (1, 11) ein Magnetfeld detektiert, so kann daraus geschlossen werden, dass die Hörsituation "Telefonieren" vorliegt. Detektieren hingegen beide Hörhilfegeräte (1, 11) gleichzeitig ein Magnetfeld, so befinden sich beide Hörhilfegeräte (1, 11) in einer Aufbewahrungsbox, die mit einem Permanentmagnet ausgestattet ist, und werden automatisch abgeschaltet.
