What is the difference between hearing aid and cochlear implant

Hearing and cochlear implantation refer to technical methods of rehabilitation of patients with hearing impairment.
People with hearing impairment are poorly receptive to speech and other sounds. Due to the fact that the structures of the outer, middle ear or part of the hair cells are damaged, they hear sounds as quiet, illegible. To amplify the sounds transmitted to the auditory system of the deaf person, hearing aids (SA) are used.

The hearing aid - is a device for amplifying speech and other sounds. It consists of a microphone, amplifier, signal converter, control elements and batteries.
Modern hearing aids
In most cases, people with hearing problems are assisted by hearing aids.


Depending on the technology used in CA, they are divided into several types: analog, programmable and digital.
At the location are allocated: pocket, behind-the-bones (most common), in-the-ear, spectacled frames and implantable СА.

With monoural hearing care, the patient wears CA only on one ear. At binauralnom-carries at once two - on the right and on the left ear.

In most cases, people are helped by SA. However, with large hearing loss, when a large part of the auditory receptors (hair cells) are damaged in a person, they do not always cope. In this situation, operation of cochlear implantation (CI) is recommended.


What is CI?

About cochlear implantation in simple words.
Cochlear implantation is used when conventional hearing aids can no longer help.
Cochlear implantation - a kind of hearing aid - is a system of measures aimed at restoring hearing loss in those people who are not helped by conventional SA.
It includes five elements that are interrelated with each other:


  1. The technical means is the apparatus itself (implant and speech processor).
  2. Selection of candidates for CI.
  3. The operation to install the implant.
  4. The first activation and tuning of the speech processor.
  5. Psychological and pedagogical rehabilitation after CI.
