  • Cochlear Implants
    • Rush Limbaugh received cochlear implant.
    • Invented by Professor Graeme Clark, author of Sounds From Silence

      • 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
    • Collection of case studies, Cochlear Implantation for Infants and Children
