Hearing can be identified as the ability of the ear to perceive sound by detecting vibrations and changes in the pressure, and convert sound waves into information the brain understands and interprets as sounds. Sounds above 88 dB are considered to be harmful and can damage hearing. Musician are exposed to the loud noise and are more likely to have a noise-induced hearing loss. As a human ear has a vital role, our group AHAAR aims to help the DJ's to prevent the ear damages.
