There are many difficulties that arise when one is faced with a hearing disability. New applications of advancing technology have the potential to enable designs capable of assisting the hearing impaired with the ability to see sound. This project seeks to provide a user with a visual representation of loud noises detected using small directional microphones. The microphones determine the location of the sound above a set decibel level and a microprocessor determines the approximate location of the sound source and displays a vertical colored bar on a video image in the direction of the noise using virtual reality glasses. Two sources of input are combined in the display: the sound that is measured with the microphones, and a camera video image of what the user sees. This information is processed using an ATmega 328P micro controller and the result is displayed on the screens of the user’s virtual reality glasses.
