ABSTRACT:
In a transmission apparatus for transmitting signals to a hearing device, as well as transmission and operating methods thereof, and a hearing aid apparatus, not only the acoustic path but also an electromagnetic path are used to transmit the same signal. So that the data rate can be reduced for low power consumption, only the envelope of the useful signal is transmitted electromagnetically. This allows a useful signal to be transmitted from one hearing device to another hearing device electromagnetically with low power consumption. The reception-end hearing device then restores the source signal, containing interference, with the electromagnetically transmitted envelope to produce an output signal.
