Cochlear Implants

According to the National Institute on Deafness and Other Communication Disorders, “A cochlear implant is a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard-of-hearing. The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin (see figure). An implant has the following parts:
• A microphone, which picks up sound from the environment.
• A speech processor, which selects and arranges sounds picked up by the microphone.
• A transmitter and receiver/stimulator, which receive signals from the speech processor and convert them into electric impulses.
• An electrode array, which is a group of electrodes that collects the impulses from the stimulator and sends them to different regions of the auditory nerve.

An implant does not restore normal hearing. Instead, it can give a deaf person a useful representation of sounds in the environment and help him or her to understand speech.” To read more: see Cochlear Implants

I use to work in Audiology and those Audiologists were specialized in detecting loss of hearing. I learned there about the Cochlear Implants. Sounds very promising and useful for people with hearing impairment. Great post!
