Hearing aids simply amplify sounds that may only be faintly detected by damaged ears. Cochlear implants, however, bypass damaged portions of the ear and directly stimulate functional auditory nerves. Cochlear implants are a remarkable example of human ingenuity. Cochlear implants actually create artificial nerve impulses to the brain, which transmit sound. In fact, it takes users of Cochlear Implant’s a bit of time to learn to recognize the new signals as sound.
