RE: Using infrared light to help deaf people hear and blind people see
"Perhaps someday an optical cochlear implant will allow deaf people to once again enjoy music and hear all the nuances in sound that a hearing person would enjoy.?
Huh? Deaf people never did hear... that's why they're deaf. They don't have the "parts" to enable them to hear. This is not a matter of "once again" enjoying music. (my daughter works with the deaf).
Can this work on someone without an inner ear to attach to?
Besides, as a musician, I'm not too sure I want to be able to hear "hundreds or thousands of frequencies". Imagine the confusion.
