The cochlear implant is the most successful medical electronic product of modern bionic technology. It has been in existence for more than 30 years and has enabled more and more hearing-impaired people to enter or return to the audible world. In developed societies in Europe and the United States, the use of cochlear implants has become very popular, and in developed regions of China, such as Beijing and Shanghai, the clinical use of cochlear implants has reached more than 10,000 cases, enabling many hearing-impaired people to enjoy the gospel brought by modern technology. However, the public in Chongqing does not know much about cochlear implants, and most hearing-impaired patients still do not know what cochlear implants are, and even the staff of hearing-impaired-related professions do not have a comprehensive understanding of cochlear implants. For this reason, it is important to write a few words in order to help. 1. What is a cochlear implant? It is an implantable electronic device that replaces a non-functional cochlea in the human body to regain or improve the sensation of sound. 2. How does a cochlear implant work? Unlike a hearing aid that simply amplifies sound, a cochlear implant can bypass the damaged part of the ear (cochlea) and directly stimulate nerve cells. 3. Is a cochlear implant right for me? Cochlear implants can help many people with hearing loss, from infants to adults. To find out if a cochlear implant is right for you, it is important to know the cause of your hearing loss, which is generally suitable for people with severe or profound sensorineural deafness. Studies have shown that adults who use cochlear implants understand utterances on average seven times better than those who use hearing aids. There were other improvements as well. In a survey of 900 cochlear implant users in the United States, the majority of respondents said they were able to communicate effectively on the phone and enjoy music with the help of their cochlear implants. With all these benefits, why wait? Nearly 80 percent of people who had a cochlear implant within a year of finding out they were eligible said they would have had it sooner if they had been given another chance.
