Implementation and verification of a platform for bluetooth linked hearing aids system with smart phone and multimedia devices

Binaural hearing aids manufacturers have been developed control and communication technology by utilizing the smart-phone and multimedia devices. However, those systems need to use a wireless repeater system or remote control. In this paper, we´ve designed and implemented a hearing aids open platform system that can combine smart phone and multimedia devices through a small sized bluetooth adaptor for the development of binaural hearing aids. And also, we implemented android based control GUI (graphical user interface) for hearing aids volume and fitting parameters control. From the experiment results, we verified open platform board and bluetooth adaptor that was successfully controlled the hearing aids, thus, it doesn´t need to a wireless repeater system and remote control.
