<p>The arrangement has an external unit (15) i.e. hearing aid remote control, producing an unmodulated carrier signal (20). A hearing aid (11) comprises a transponder (13), which receives the unmodulated carrier signal. Data to be transferred is modulated by the unmodulated carrier signal. The hearing aid backscatters a modulated carrier signal (21). Another hearing aid (12) comprises another transponder (14), which adjusts the backscattered and modulated carrier signal. Frequency of the unmodulated and modulated carrier signals lies in UHF range. An independent claim is also included for a method for wireless transmission between two hearing aids.</p> |
