What types of hearing loss can a cochlear implant assist you with?
Learn more about the types of hearing loss a cochlear implant can assist you with. A cochlear implant is a surgically inserted hearing device for the deaf or very hard of hearing. The device sends sound impulses to nerves inside the ear, which then signal the brain.

Do cochlear implants work with nerve damage?
Although many auditory nerve fibers may be intact and can transmit electrical impulses to the brain, these nerve fibers are unresponsive because of hair cell damage. Since severe sensorineural hearing loss cannot be corrected with medicine, it can be treated only with a cochlear implant.
Can cochlear implants cure nerve deafness?
Cochlear implants do not cure hearing loss or restore hearing, but they do provide an opportunity for the severely hard of hearing or deaf to perceive the sensation of sound by bypassing the damaged inner ear. Unlike hearing aids, they require surgical implantation.
Can nerve deafness in a person be corrected?
There is no cure for auditory neuropathy. The variable nature of this hearing disorder means that some treatments work in some cases and not others.

The internal portion is implanted beneath the skin, behind the ear. When the receiver gets the digital signals, it turns them into electrical impulses. These impulses are sent to electrodes in the cochlea, which stimulates the cochlear nerve. The nerve forwards them to the brain. The result is a sense of hearing.
How does a speech processor work?
It consists of a microphone, which receives sound waves. A speech processor analyzes the sounds and turns them into digital signals. These signals are sent to a transmitter, which forwards them to the internal receiver. The transmitter and receiver are held together by a magnet.

Cochlear implants are surgically-implanted devices that provide electrical stimulation to the cochlear nerve, essentially bypassing the damaged regions of the inner ear/cochlea. When wearing the external part of the implant, acoustic sounds are processed into electrical signals and transmitted to the internal device. The internal device then stimulates the cochlear nerve, which carries the signal to the auditory cortex of the brain.
What is single-sided deafness?
Single-sided deafness – or SSD – is when a person has severe to profound hearing loss in one ear but has normal hearing in the other ear. Even though individuals with single-sided deafness can still hear normally out of one ear, the lack of access to sounds in both ears has numerous adverse effects. For one, listening in a noisy situation, like a restaurant or loud classroom, can be very challenging as they cannot suppress unwanted background noise with just one hearing ear. Further, localizing where sound is coming from is more challenging. This not only causes personal frustration but can also present safety concerns.

Therefore, clarity remains compromised.
