Who can they help?

Cochlear implants can help people who:

• have moderate to profound hearing loss in both ears
• receive little or no benefit from hearing aids
• score 50% or less on sentence recognition tests done by hearing professional in the ear to be implanted
• score 60% or less on sentence recognition tests done by hearing professionals in the non-implanted ear or in both ears with hearing aids.

Many people have cochlear implants in both ears (bilateral). Listening with two ears can improve your ability to identify the direction of sound and separate the sounds you want to hear from those you don’t.

How do they work?

Many people suffer hearing loss because their hair cells in the inner ear or (or cochlea) are damaged. The cochlear implant enables the sound to be transferred to your hearing nerves and enables you to hear. The process is described below:

1. A sound processor worn behind the ear or on the body captures the sound and turns it into digital code. The sound processor has a battery that powers the entire system.
2. The sound processor transmits the digitally-coded sound through the coil on the outside of your head to the  Cochlear implant cost in Pakistan.
3. The implantconverts the digitally-coded sound into electrical impulses and sends them along the electrode array placed in the cochlea (the inner ear).
4. The implant’s electrodes stimulate the cochlea’s hearing nerve, which then sends the impulses to the brain where they are interpreted as sound.
