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
Ossicular Chain
The Ear drum sets the Ossicular chain
in motion
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
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.
Alessandro Volta
André Djourno performs the first cochlear implantation in France,
André Djourno
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 over
Have 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.
