Cochlear implants must be expensive. Cochlear implants and hearing AIDS are both means to assist hearing-impaired patients to obtain hearing. However, there are great differences between them, mainly as follows: 1, with different mechanisms. Cochlear implant directly stimulates auditory nerve by crossing the inner ear, hearing aid is auditory compensation, and amplified sound is auditory compensation by residual hair cells. 2. Their scope of application is different. Cochlear implants are suitable for patients with severe cochlear lesions, severe hearing loss in both ears and inability to benefit from hearing AIDS. Hearing AIDS are suitable for pre-cochlear and cochlear lesions. 3. They have their own advantages and disadvantages in hearing compensation. The low frequency compensation of cochlear implant is not as good as hearing aid, and the high frequency compensation of hearing aid is not as good as cochlear implant, so some people abroad use hearing aid and cochlear implant at the same time. Now one direction of hearing aid technology development is to increase bandwidth and compensate for more high frequencies.
1. The cochlear implant directly stimulates the auditory hair cells of the cochlea through electrical stimulation, and transmits electrical signals to the brain to form sounds; Hearing AIDS compensate for hearing by amplifying the sound they hear and increasing the volume.
2. Cochlear implants need to be implanted under the skin through surgery; Hearing AIDS usually only need to be inserted into the ear canal and worn in other ways.
3. Cochlear implant is to compensate for the hearing loss of severe to extremely severe deafness; Hearing AIDS can only compensate for severe hearing loss at most.
The choice of cochlear implant or hearing aid fitting depends on the degree and type of hearing loss.
Cochlear implants are more expensive than hearing AIDS.

Cochlear implants are definitely more expensive.
Generally speaking, hearing AIDS are suitable for people with hearing loss within 90 decibels. If the hearing loss exceeds 90 decibels, you can also use high-power hearing AIDS, which may not be as effective as cochlear implants, but it is not exactly the same. Hearing AIDS with hearing loss 1 10 dB are also very effective. This varies from person to person. Cochlear implant not only includes the research and production of the product itself, but also includes a series of expenses such as surgery, which is much more expensive than hearing AIDS. You can go to the nearest hearing center for consultation, and you don't have to have a cochlear implant.
Cochlear implants are expensive. Cochlear implant is the first "real artificial organ", which probably involves chip, independent power supply, electrode design, processing technology, immune materials, battery control, language program processing, acoustic envelope program and other technical difficulties.

Cochlear implant is more expensive, hearing loss, hearing AIDS are the first choice, hearing AIDS are not effective, consider cochlear implant.
