Recently, the development of binaural hearing aids are rapidly developing with the improvement of wireless communication technology and integrated circuit design. The binaural hearing aids manufacturers are developing control technology using the multimedia equipment and smart-phone for its hearing aids control. In this paper, we designed and implemented the hearing aids system that is combined open platform board and bluetooth dongle for 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 dongle that was successfully controlled the hearing aids system volume using smart-phone GUI.
