What is Sound?
When a stone is thrown in water, waves spread in circles. Similarly a sound source spreads waves, which are perceived by the ears. Sound pressure is measured in Decibels. For example, rustling of leaves is low decibel sound, and loud sounds, like crackers (about 120 decibel), produce discomfort to the ears and then to the brain.
Anatomy of the ear
How do we hear
The sound passes through the ear canal to fall on the parchment like structure called ear drum (Tympanic membrane). The sound pressure vibrates the membrane, which moves the three bones attached to it. The bones are named after their looks i.e. hammer (Malleus), anvil (Incus) and stirrup (Stapes). Incidentally, Stapes is the smallest bone in the body. The sound energy is then passed on to the inner ear.
COCHLEAR implant is a small intricate electronic device, used in patients who are profoundly deaf or severely hard of hearing. It is implanted surgically to produce useful hearing in these patients who do not benefit from hearing aids.
How does COCHLEAR IMPLANT work
The sound is picked up by the microphone and interpreted by the sound processor. The interpreted sound is delivered through transmitter coil to the implanted receiver. The implanted receiver sends the electrical signals through the electrodes placed in cochlea. These electrical signals are then send to the brain.
Who is eligible to receive COCHLEAR IMPLANT
A number of medical and audiological assessments are required to determine if a person is candidate for Cochlear Implant.
Generally, the following criteria apply:
- The potential recipient must have a severe to profound sensori-neural hearing loss in both ears.
- They must gain little or no benefit from the use of hearing aids.
- The ears must be free from infection.
- The inner ear must be reasonably well-formed.
- They must be medically suitable to undergo surgery for a Cochlear Implant.
