The human Hearing sense
The outer ear picks up the sound vibrations
The Sound vibrations are directed to the middle ear by the ear channel
The human Hearing sense
The Ear drum sets the Ossicular chain in motion
Ossicular Chain
The Ossicular chain in its turn sets the Perilymph (Fluid in the cochlear) in the cochlear in motion
The human Hearing sense
The Mechanical vibrations are converted to the electrical pulses by the hair cells
The electrical pulses are sent to the auditory cortex by the auditory nerves
Cochlear Implant
Alessandro Volta
Some facts about the Cochlear Implant:
Around 1790 Alessandro Volta experimentally discovered that electrical stimulation in the auditory system can create a perception of sound.“ It is like a thick boiling soup“, He said.
André Djourno performs the first cochlear implantation in France,
Dr. Michelson's patents and device are thought as the first cochlear implants.

Cochlear Implant
A cochlear implant consists of two parts:- The sound processor- The implant
A flexible electrode array is inserted into the entire cochlear
Cochlear Implant
The sound vibrations are converted to electrical signals and transmitted through the skin into the implant via the coil.
The implant creates electrical pulses from the received signals and sends them to Auditory Cortex via Cochlear and auditory nerves.

Brief overview
Who is a CI Candidate?
For young children: 12 months to 2 years Have profound sensorineural hearing loss (nerve deafness).Receive limited benefit from hearing aids.
Children: 2 to 17 years Have severe-to-profound sensorineural hearing loss (nerve deafness). Receive limited benefit from hearing aids.
Adults: 18 year and overHave moderate-to-profound sensorineural hearing loss (nerve deafness).
Receive limited benefit from hearing aids.
Score 50 percent or less on speech recognition tests in the ear to be implanted and 60 percent or less in the non-implanted ear when using hearing aids.
