WidexLink is used for the transmission of sound from external devices to the hearing aids when the user watches TV, talks on his mobile phone, or listens to music.
The technology is also used for the transmission of data between the remote control (RC-DEX) and hearing aid, and in the exchange of synchronisation data between hearing aids (InterEar communication).
We are convinced that wireless technology is the future in the hearing aid industry. However, the success of any given wireless transmission technology will depend on at least three key issues when applied to hearing aids: Sound quality, transmission robustness, and power consumption.
It is no simple matter to design a system that is able to maintain high audio quality, low battery drain, and robustness against transmission errors at the same time.
In order to achieve these goals, several key components of the wireless system have been carefully designed.
The Audibilty Extender has been tested with adults as well as children by Widex research facilities, including ORCA US. We have positive results from these clinical trials suggesting that the linear frequency transposition facilitates better speech intelligibility and access to environmental sounds.
