Write An Essay On Cochlear Lear
Just like in any population there is always something that threatens the well being of the group especially when the group is in the minority. For the deaf community the cochlear implant has caused an uproar over the years. A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear. But unlike its counterpart hearing aids, which makes sound louder, cochlear implants do the work of damaged parts of the inner ear(cochlea) to provide sound signals to the brain.
It all started with Alessandro Volta when he managed to stimulate his internal ear by using an electrical current the year 1800. Since that time there have been major modifications from the look and all the way to the pitch and stimulation …show more content…
First there is a sound processor that captures sound and turns it into digital code that is worn behind the ear. This piece is battery powered and it powers the whole system. From here the sound processor transmits the digitally-coded sound through the coil on the outside of your head to the implant. In which the implant then converts the digitally-coded sound into electrical impulses and sends them along the electrode array placed in the cochlea. Lastly the implant's electrodes stimulate the cochlea's hearing nerve, which the4n sends the impulses to the brain where they are interpreted as sound. Opposed to the hearing aid the cochlear provides a better hearing quality and a previous study has shown that people with the cochlear implant achieve an average of 80% sentence understanding, compared to the significantly lower 10% sentence understanding from hearing aids. But many factors go into the cochlear process. This type of process is a case by case basis depending on different people because the experience is different for each of the users of the cochlear. Here is a list of the things that should be taken into consideration: how long they have had hearing loss before receiving a cochlear implant, how severe their hearing loss is, how damaged their cochlea is as well as other medical
