ABSTRACT
(PIC16F877A) PIC Microcontroller based digital electronic system to allow deaf people to hear the sounds via bone conduction by wearing an intra-oral device and a small microphone in the deaf ear to regain lost hearing. This device consists of GSM modem, PIC microcontroller and audio amplifier unit. GSM modem will receive the incoming calls and answer the calls automatically Via AT commands. The incoming voice signal converted in to low frequency vibration signals that is fed through the teeth to the cochlea via bone conduction. The system is implemented by PIC midrange controller based hardware and low cost GSM module, which makes it economic, reliable and efficient. It is the world’s first removable and non-surgical hearing solution to use the Well-established principle of bone conduction to imperceptibly transmit sound via the teeth. It is simple, Removable, and very Non-Invasive. This hearing device is designed to use the natural amplification of your ear. Any sound in that that coming from GSM Modem. It uses a digital processor (PIC16F877A) to transmit to the sound to a piezoelectric actuator, which needs very little power to generate the vibrations that travel through bone, which in turn sends those sound vibrations into your cochlea through your teeth. This way, the sound is transported from your impaired ear directly to your hearing ear this hearing device is a flat piece that contains a sealed rechargeable battery, and electronics and wireless capabilities that can pick up sound transmissions from the behind-the-ear microphone.
