A cochlear implant (CI) is a device that can help people with severe to profound hearing loss hear better. This device is meant for those with single-sided deafness, and severe to profound mixed or sensorineural hearing losses. Often, people who have these conditions are unable to use traditional hearing aids or have limited success with them.
WHAT IS A Cochlear Implant?
A cochlear implant (CI) is a surgically implanted medical device that replaces the function of the inner ear (cochlea) and is designed to bypass the damaged portions of the ear to deliver sound to the hearing nerve. The device has an external and an internal component. The external portion is known as the processor and is worn above and behind one or both ears. The internal portion is called the implant. The implant is placed into the inner ear (cochlea) by a surgeon and communicates with the external processor through a magnet placed directly under the skin.
HOW A CI WORK
Microphones on the sound processor pick up sounds, and the processor converts them into digital information. This information is transferred from the processor to the implant. The implant sends digital sound signals down the electrode into the cochlea. The hearing nerve fibers in the cochlea pick up the signals and sends them to the brain. The brain then decodes the signals and processes the information as incoming sound.
The cochlear implant is easy for the user to operate and can connect with cellphones, wireless devices, music, etc.
