There are many different people in the world that suffer from complete hearing loss. Even with hearing aid devices they have not been able to recover their hearing because of severe damage or deformity. However, the electric cochlear implant is granting new hope to people like this all over the world. With the ability to affect the brain and associated nerves directly, there is no need for this device to use normal hearing pathways to achieve hearing. This article will look at the advantages and disadvantages of this item as well as the way that it functions.
What Are Advantages And Disadvantages?
There are many different advantages and disadvantages of using these devices. The main advantage and motivating factor for most people is that it can restore a level of hearing to people that have never had it before. Also, for many people, these devices give them hearing that is complete enough that they can effectively hold a conversation and utilize modern technology. However, one of the drawbacks of using this device is that it is expensive and does not always have the proper outcomes because of different physiology. Still, it remains a significant option for people with complete hearing loss.
What Makes An Implant?
Each implant is made up of five different items that are used together to create the sensation of hearing. There are two parts that are implanted into the body as well as three parts that are on the outside of the body. The two parts on the inside of the boy are called the receiver and the electrode bundle. The parts that are not embedded beneath the skin are the microphone, the transmitter device, and also the speech processing unit. When used properly, the electric cochlear implant uses all of these parts in unison to create the ability to hear sounds from the environment directly in the brain.
How Does This Happen?
In order for the devices to work properly, there is a very specific order that the sound must go through inside of the implant. The microphone needs to pick up as much sound as it can from the outside environment and bring it into the device so that it can be processed in the speech processor box. Once the sound has been digitized and made ready for transmission, it is sent to the transmitter that is located behind the ear. This tool takes the digitized sound and broadcasts it so that it can be picked up by the receiver that is embedded under the skin. The receiver brings this sound in and sends it along a man-made pathway to the electrode bundle. After it goes to the electrode bundle, the device uses electric signals to stimulate the nerves so that they tell the brain that it is picking up real sound. This creates the synthetic hearing sensation that has allowed thousands of people to reclaim their hearing.
