Abstract:
1. A wireless transmission system comprising: a plurality of hearing devices, each hearing device comprising a signal processing unit and an electro-acoustic transducer, the signal processing unit being operatively connected to the electro-acoustic transducer; means for transmitting a plurality of audio signals to the hearing devices, wherein each audio signal is transmitted at a configured carrier frequency; each hearing device further comprising means for receiving at least one of the plurality of audio signals, said means for receiving at least one of the plurality of audio signals being operatively connected to at least one of the signal processing unit and the electro-acoustic transducer; means for remotely generating and wirelessly transmitting configuration parameters to the hearing devices, for configuring the means for receiving at least one of the plurality of audio signals; each hearing device further comprising means for receiving said configuration parameters, said means for receiving said configuration parameters being comprised in said means for receiving at least one of the plurality of audio signals; and each hearing device further comprising means for tuning the means for receiving at least one of the plurality of audio signals to an audio signal according to the configuration parameters, wherein the plurality of audio signals as well as the configuration parameters are transmitted wirelessly via independent transmission channels, whereby the configuration parameters are transmitted at a predefined carrier frequency via a common transmission channel shared by all said means for remotely generating and wirelessly transmitting configuration parameters and all said means for receiving the configuration parameters.
