What are Cochlear Implants?
Cochlear implants are electronic medical devices that aims to replace the damaged inner ear. More specifically, they function as a simpler cochlea that processes sounds and turns them into electronic signals, which can then be sent to the brain as perceptions of sound.
The cochlear implant consists of:
- A sound processor
- Worn behind the ear or on the body
- Captures sound through a microphone and turns it into digital code
- Sends the digital code to the implanted receiver through the transmitter system
- An implant
- Converts the digital code into electrical impulses
- Sends the electrical impulses to the implanted electrode in the cochlea
- Stimulates the auditory nerve, which interprets the electrical impulses as sounds
