What is the difference between a cochlear implant and a hearing aid?
cochlear implant and hearing aid differ in that the cochlear implant is implanted surgically into the ear. Individuals with significant loss of hearing or deafness are considered candidates for a cochlear implant if the hearing aid is not option. In general, individuals who have suffered a slight to medium hearing loss, as a result of environmental factors, age or disease, benefit from using the hearing aid. Unlike the hearing aid, the cochlear implant is permanently placed in the ear and may not be perverted. Although the cochlear implant and the hearing aid are designed to help restore hearing, they work fundamentally different means. It is important to understand the differences in the degrees and types of hearing loss before choosing between the cochlear implant and the hearing aid. While the hearing aid strengthens, the cochlear implant stimulates the auditory nerve. The cochlear implant does not renew hearing but offers adequate replication of the sound that isDotec can understand.
Sensorineural hearing loss occurs when the hair cells of the inner ear suffer irreversible damage. Individuals with this form of hearing loss have difficulty in resolving sounds and understanding of speech, especially if there is significant background noise. Individuals with sensorineural hearing loss often experience the persistent buzzing in the ears and may have a deteriorated balance that causes dizziness. Sensorineural hearing loss can be congenital, which means it is present at birth or may be due to infection, illness or injury.
cochlear implant is composed of two primary parts, One, which is implanted under the skin behind the ear and others, which is placed outside the ear, as the hearing aids would be. The inner part contains a receiver containing electrodes that are connected directly to the cochle and are used to stimulate the auditory nerve. The outer part contains a microphone that zvEdne sound and adds it to the electrodes in the ear.
cochlear implantation is a two -stage process. Initial surgery is carried out to implant electrodes and a subsequent visit involves adapting an individual with an external speech processor and a microphone. Once both parts of the implant are located, the device is activated. Individuals who receive a cochlear implant are obliged to maintain annual meetings to be modified as needed. In addition, recipients of cochlear implants undergo extensive speech therapy and rehabilitation.
conductive hearing loss (CHL) is a progressive loss of hearing over time and can be treated asluchalo. CHL is often caused by the accumulation of fluid or wax in the ear canal. Infection that may occur in measles and scarlet fever, and injury to inner ear can also contribute to a gentle, progressive hearing loss in the long run. Individuals who are regularly exposed to loud sounds such as in the working environment are tIf threatened Chl.
individuals with conductive hearing loss are considered suitable candidates for hearing aid that works by amplifying the sound. The degree of hearing loss determines the amount of amplification necessary to restore hearing. Depending on the type of hearing aid used, it can sit in the ear canal inside the farthest part of the ear or behind the ear. As with a cochlear implant, the hearing aid does not cure hearing loss, but allows someone to hear better. In some cases, if the CHL is sufficiently serious, the individual may have a choice between the cochlear implant and the hearing aid.
