How Effective Are Cochlear Implants As A Hearing Loss Treatment?

Although cochlear implant is mostly used for deaf people and those who were born with severely impaired hearing, it can also serve as an effective Hearing Loss Treatment. For instance, aged individuals who have lost most of their hearing can benefit from it by associating the signal that the implant produces with the sound they are familiar with.

People who get the best out of this implant also undergo therapy so they can learn and re-learn to adopt with this electrical stimulator of sound. Undergoing a surgical implant does not guarantee that everyone will get the same result or will exhibit the same hearing level using this device.

Hearing Loss Treatment: Parts Of A Cochlear Implant

A cochlear implant is composed of two parts. One is found on the external and the other is implanted inside the ear. These two are functioning together to capture sound, transform it into a digital information and then into electrical signals that trigger the hearing nerve and allow the brain to perceive the sound.

On the external part of the device one can find a microphone, a speech processor, and a transmitter. The microphone picks up sound from the environment; the speech processor filters the sound and turns it into digital information; and the transmitter sends the processed sound to the internal device through electromagnetic induction.

Meanwhile, the internal part of a cochlear implant consists of a receiver and a stimulator, and an array of electron wounds through the cochlea. The receiver and the stimulator convert the digital information into electric impulses and send them into electrodes through an internal cable. The electron wounds transmit the impulses to the nerves in the scala tympani, which will be then directly sent to the brain through the auditory nerve system.

Hearing Loss Treatment: The Future It Holds For Other Types Of Hearing Loss

Cochlear implants have been a product of intensive research for over four decades. And until now, various researches are being conducted and funded to make it even more useful for people who are experiencing other types of hearing loss. The National Institute on Deafness and other Communication Disorders, for instance, has been supporting research for the improvement of benefits provided by the implant. Among them include the use of a shortened electrode array for individuals whose hearing loss is limited to higher sound frequencies.
