Design student develops first dental MP3 player
from Dental Tribune International
A young artist has developed a device that combines a digital music player with mouthpiece jewelry known as a grill, usually associated with the hip-hop and rap culture. It is worn like a retainer over the teeth and transmits sound using bone conduction hearing instead of earphones. The innovative device, called Play-A-Grill, works similarly to a cochlear implant, which is surgically implanted to provide people who are deaf or severely hearing impaired with a sense of sound.
