Abstract (en)
[origin: US2010278367A1] A configuration and an associated method for the wireless transmission of data between hearing devices include an external unit which generates and emits a carrier signal, a first hearing device with a first transponder which modulates and back-scatters the carrier signal and a second hearing device with a second transponder which receives the carrier signal that is scattered backwards and forwards and modulated by the first transponder. The external unit is, for instance, a hearing device remote control. Advantageously, little or no additional energy is needed in the hearing device for the wireless data transmission. The energy for the supply of the first transponder is delivered by the carrier signal of the external unit.
