Several hearing aids have been invented for outer ear drum problems whereas inner ear drum problem is permanent and it can be fixed only by surgical means. This hearing aid is designed to use the natural amplification of ear. This device consists of a AVR controller, a GSM module, a playback module and a relay. Any signal that is received by the GSM module is transmitted to the piezoelectric actuator by the AVR controller which generates the vibrations that is sent to cochlea through the teeth. This way the sound is imported from the impaired ear to hearing ear. This device can be fixed on the teeth and no alteration of the teeth is required. It is completely non-invasive. The GSM module receives incoming calls and automatically answers the calls via AT commands. The playback module allows the user to hear music and receive the incoming calls giving priority to calls. A relay is used to switch between the music playback and GSM module. It is simple, removable and customizable according to the users will.
