Abstract

BC hearing aids are the only non-surgical devices used for conductive hearing loss. We proposed a bone conduction hearing aid that is manufactured in the form of a dental implant type, and the excitation is directly transmitted to the bone by integrating it via bone conduction through the tooth. This doesnt require any of your teeth to be altered, and the device can be inserted and removed easily. This hearing device is designed to use the natural amplification of your ear. Any sound coming from Modem is attenuated and it uses a digital processor (PIC16F877A) to transmit the signals to the soundbite module 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.We measured the thresholds of bone conduction hearing (via the teeth) with the use of a bone conductive actuator. The findings indicated that our design was more acceptable for users with SSD due to its effectiveness, providing excellent concealment, which could increase users equity and confidence.
