Rush Limbaugh received cochlear implant.
Invented by Professor Graeme Clark, author of
Sounds From Silence
First successful implant 1978
Clark and University of Melborne developed the first multi-channel implant, Cochlear Nucleus 22 in 1984.
Since then 45,000 people worldwide have received them
Clark now heads the Bionic Ear Institute
How do we hear?
Sound vibrates ear drum
Ear drum vibrates three bones (malleus, incus, stapes) in the inner ear
These bones vibrate the cohlear spiral shell (with lower frequencies at the base)
Hairs in cochlea vibrate and send signals to auditory nerve
How do implants work?
22 electrode array that is inserted into cochlear spiral shell.
External processor performs signal processing function to extract 22 frequencies that make up incoming sound (i.e. perform discrete 22 term Fourier transform).
These signals are passed to the appropriate sensor in the array
Electrical interaction of the sensor and nerve excites the auditor nerve
For the profoundly deaf, this is a clear option
For those with partial hearing, the option is not so clear
