Understanding The Functionality of The Cochlear Implant

The World Health Organization (WHO) estimates that around 278 million people worldwide are diagnosed with moderate to severe hearing loss in both ears. Diagnostic medical records by the World Health Organization (WHO) suggest that the incidence of hearing loss often increases with the increase in the age and life expectancy of the population. Furthermore, according to the 2012 health hearing aid, the experience of most hearing impaired patients is sensory hearing loss, and the neural pathway from the inner ear hair cells or the inner ear to the brain is seriously damaged.

Most hearing loss cases are treated with many electro-acoustic instruments such as hearing aids, personal hearing aids, bone fixed hearing aids, and cochlear implants. Among these devices, hearing aids and cochlear implants are the most commonly used devices for treating sensorineural hearing loss. 1 Traditional hearing aids can amplify sound to improve hearing function. Distant (95 dB or more) Sensory hearing loss. Language clarity and comprehension are measured by word recognition (formerly known as speech recognition), and the score for non-disabled people is usually> 90%. In recent years, the cochlear implants have been used for the elderly 3 The cochlear inner ear is not a treatment option for patients with conductive deafness or central deafness.

People's perceptions of cochlear implants are completely different from simulated hearing. Since it only provides a representation of the sound, we can not even even say that it listens at the cochlear implant. Since the cochlea bypasses the entire auditory process, it can not be called hearing. So far, I still do not know what to call it. Not only you have never heard about cochlear implants, but what you are feeling is the reduction in the low resolution signal that the frequency nuance is lost. The volume of the signal does not matter. The resolution is. Artificial hearing is a digital sound of the cochlear implant, and today's high vision television is a black and white television of the 1950s using an antenna. You think the latter image is good, but it does not have the former details.
