Abstract (en)
[origin: EP1983800A2] The hearing device has a transmission device for wireless data transmission in a main frequency band. A control device controls a loudspeaker with a control signal, where a frequency spectrum of the control signal possesses a notch (E) in a region of the main frequency band. The control signal of the control device is pulse-width-modulated. The transmission device has a band pass filter, where the data transmission by the transmission device takes place in a wide band of the frequency spectrum. An independent claim is also included for a method for operating a hearing device.
