There is a big difference.
CI may enable to hear what HA does not, because CI work in different way than HA.
This is how HA works:
""Hearing aids are one of the fundamental devices used by hard of hearing and late deafened people. They work by amplifying sound. There are many different types of hearing aids, each addressing particular needs.""
The HA AMPLIFY your NATURAL hearing or rather what's left of it.
This is how CI works:
""What is a cochlear implant?
A cochlear implant is a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard of hearing. The implant is surgically placed under the skin behind the ear. An implant has four basic parts:
A microphone, which picks up sound from the environment;
A speech processor, which selects and arranges sounds picked up by the microphone;
A transmitter and receiver/stimulator, which receive signals from the speech processor and convert them into electric impulses;
And electrodes, which collect the impulses from the stimulator and send them to the brain.
An implant does not restore or create normal hearing. Instead, under the appropriate conditions, it can give a deaf person a useful auditory understanding of the environment and help him or her to understand speech.
A cochlear implant is very different from a hearing aid. Hearing aids amplify sound. Cochlear implants compensate for damaged or non-working parts of the inner ear.""
That is BIG difference.
