Abstract (en)
[origin: EP1995990A2] The device has a radio device for transmitting signals to another hearing device, where the radio device comprises an antenna circuit (2) for transmitting and receiving the signals. The antenna circuit comprises a self-exciting oscillation circuit. The antenna circuit consists exclusively of an inductance capacitance (LC) oscillation circuit. A receiver circuit (3) device comprises a median filter (34), which is configured to reduce noise signals. A half-duplex transmission line is established with the radio device. The signal transmission is implemented in the long-wave range with the radio device.
