Explanation:
The cochlear implant is a high-tech active implantable medical device consisting of a transducer that transforms acoustic signals into electrical signals that stimulate the auditory nerve.1 These signals are processed by the different parts that make up the cochlear implant, some of the which are placed inside the skull and others outside. It helps people to listen and can be used for people who are deaf or hard of hearing. It is not the same as a hearing aid, as it is surgically implanted and works differently.
