The Difference Between Cochlear Implants
and Hearing Aids
So how does the cochlear implant work?
It is made up of two parts: the internal receiver/stimulator and the microphone
and magnetic transmitting coil. The internal receiver is surgically implanted in
your ear, while the microphone and coil fit externally behind the ear and on the
side of the head. The microphone picks up sound, translates it into coded
signals and sends it through the transmitting coil to the implant located under
the skin. Electrical energy is then sent to the electrodes in the cochlea, which
stimulates the auditory nerve and travels to the brain for interpretation.
Is a cochlear implant right for you?
Most cochlear implant recipients try hearing aids out first. If you’ve tried
hearing aids and they haven’t benefitted you due to profound sensorineural
hearing loss or congenital deafness, then cochlear implant surgery may be
something to consider. To determine whether or not it’s the right move, you
will need to have audiologic testing, a medical exam and possible x-rays/MRI.
Fortunately, the majority of individuals with mild to moderate hearing loss will
benefit from traditional hearing aids. Although hearing aids don’t process
sound like cochlear implants, they are less expensive and can be manually
adjusted, repaired, replaced and removed easily.
