Just thought I would talk about the components of the CI (cochlear implant) and how it works.
After I ran into two people who thought that once I had the internal implant in, I was going to automatically start hearing "normally." It's not like a pair of prescription glasses-presto-your vision is corrected. The internal implant alone does not work by itself. It needs the external components of the CI, too-the processor and the magnet in order to work. And I still needed to be activated and get a map at the time. (A map is a personal, individualized programming of the CI. Like fingerprints and snowflakes, no two are the same, even for bilateral implantees. Everyone has their own comfort level of what they can hear and it is adjusted to fit that threshold.)
I copied this from the Cochlear Freedom literature I got from the audiologist.
Each caption in the above graphic talks about the implant: MRI safe, up to 1.5 Tesla with the magnet removed, built with titanium and platium (tested by the US Military), has 22 electrodes, and a soft tip to minimize force during surgery thus it could preserve residual hearing.
The picture below gives you an idea of the internal implant's size.
In the above picture, numbers 1 and 2 are described1) BTE (behind the ear) speech processor
2) cable and coil
1) Sound Processor - external component that converts sounds into digital signals 2) Digital signals are sent to the internal implant 3) Electrode array - internal implant converts digital signals into electrical energy, sending it to an elctrode array inside the cochlea 4) Hearing nerve - Electrodes stimulate hearing nerve, bypassing damaged hair cells, and the brain perceives signals as sound.
