The CI helps some people more than others. Hearing sounds with a CI is different from normal hearing. Recipients have to learn to interpret sounds that they may hear. It may take some time and experience with the CI before recognition improves. The implant centre conducts a careful evaluation to determine if an individual is an appropriate Cochlear Implant candidate.
Audiological tests establish the level of hearing loss.
Hearing aids and other devices are fitted to establish whether or not these devices might be beneficial. Each individual is counselled regarding the potential benefits and limitations of the Cochlear Implant. If the audiological tests indicate that the person might be a candidate, medical tests are performed. X-rays are taken to see if the cochlea is suitable for an implant. General tests are also performed to ensure that the individual can successfully undergo general anaesthesia and surgery.
