Cochlear Implant

What is a cochlear implant?

A cochlear implant is an implanted device that provides access to sound to those who have severe or profound hearing loss by electrically stimulating nerves in the inner ear. It works for both children and adults.

Our cochlear implant has the two following components:

External Part:

The sound processing unit comprises of a battery pack and a sound processor.

The sound processor has an in-built microphone and innovative technology that provides a pure and a natural sound by using unique algorithms.

Internal Part:

The internal implant is surgically placed, with electrode array positioned in the cochlea.

Receiver of the implant, which is completely free from electronics, receives electric signals from the external part and sends them to the electrodes which further stimulate the inner ear.

How a cochlear implant works

  • Microphone & Processor: Microphone picks up the sound signals and the processor convert them into electric analog signals.
  • Receiver : These electric signals are sent to the receiver of the internal implant.
  • Cochlea : The receiver transmits these signals to the electrodes stimulating the cochlea.
  • Auditory Nerve : The auditory nerve sends these signals to the brain, which interprets them as sound.


  • Directly stimulates the auditory nerve.
  • Treats Severe to profound hearing loss
  • Effective even if inner-hair cells are damaged


  • Amplifies sounds in order to be detected by damaged ears.
  • Treats mild to severe hearing loss
  • Not much effective in case inner-hair cells are damaged.

Candidacy of cochlear implants

In Babies & Children:1

  • A baby of 12 months- 23 months of age with profound hearing loss.
  • A child over 2 years with severe to profound hearing loss

In Adults :

  • Adults that have Moderately Severe to Profound hearing loss
  • Open-set sentence recognition scores less than or equal to 50-60%

Know if you or your child is a candidate:

I am a parent and wish to see if my child is a prospective candidate

a) Does your child have a delay in his/her speech and/or language skills?

b) Do others (ex. Family members, friends or neighbours) have difficulty understanding his/her speech?

c) Does your child have difficulty interacting and communicating with same-age peers?

d) Does your child show a delay in reading acquisition and/or reading fluency?

e) Does your child show irritation with poor communication results at home, school, or social settings?

f) Does your child depend on visual signs to interact successfully at home or school?

I am an adult and I wish to see if I am a prospective candidate:

a) It is challenging for me to follow conversations without lip reading

b) I struggle hearing properly in a noisy environment or a group as compared to hearing in a quiet surrounding

c) It is difficult for me to follow most of my telephone conversations

d) I find it difficult to follow conversations or noises in situations where lip reading is not available

e) I separate myself socially as the effort to listen and understand is overwhelming & irritating

Listening with two ears

While a unilateral cochlear implant can give you access to hearing, listening with two ears has multiple benefits2,3,4


Bilateral implants help you with identifying the source of sound from a distance while you are crossing roads, driving, identifying alarming sounds etc.

Performance in school

Listening with two cochlear implants provides better sound intensity, which can possibly help children to learn faster & easier at school.

Speech Understanding

The increased loudness & sensitivity to differences in intensity & frequency improves speech understanding in both quiet & noise. This may improve speech outcomes like a normal hearing child.

Reduced listening efforts

Two cochlear implants can reduce the extra concentration on a recipient’s mind as less effort and focus is needed while listening continuously.

Social Life

Going out with a group of friends to a social event or place like a café becomes more fun and interactive as two implants provide better hearing in noise.

Enjoy Music

Listening from both ears is better than one. Music can be fully enjoyed and appreciated by listening from both ears.

If hearing loss is not addressed in a child

Not addressing hearing loss also has an impact on a child. Apart from the ability to acquire language skills, obstacles in communication for a child may have emotional consequences like stress, feeling of anger and loneliness.5

Neubio strongly believes that each child must have an opportunity to hear and experience the world through sound.
