Abstract: A hearing aid (100) comprises first wireless link means configured to receive a first data signal using a first carrier frequency and second wireless link means configured to receive a second data signal using a second carrier frequency and wherein a first electrical antenna of the first wireless link means also forms part of a first band pass filter of the second wireless link means. The invention provides a hearing aid, a binaural hearing aid system and a method of receiving a first and second wireless signal.

Abstract: An frequency shift keying (FSK) transceiver for use in a hearing aid is capable of automatic tuning of the transceiver frequency. The automatic tuning makes use of a phase difference detector and a tuning manager adapted to control the frequency of a resonant circuit of the FSK transceiver according to information received from the phase difference detector. The phase difference detector measures the phase difference across a component of the resonant circuit of the FSK transceiver. If the phase difference of a binary FSK symbol is equal to the phase difference of the opposite binary FSK symbol, the resonant circuit is tuned, otherwise the tuning manager performs a tuning procedure in order to minimize the difference in phase differences, and adjusts the frequency of the resonant circuit accordingly.

Abstract: A storage system for storing a hearing aid comprises means for providing power (101), a storage space (102) for containing a hearing aid, output means, communication means through which data from the hearing aid is received wirelessly and a processing unit for processing data received from the hearing aid. The output means is capable of providing functioning and guiding information (104) concerning the functioning of the hearing aid and for guiding the user through positioning of the hearing aid, respectively. The invention further provides a hearing aid, a kit and a method of testing a hearing aid.
