Incoming sounds are converted to electrical currents and directed to a number of contact points on the internal wire. This operation creates an electrical field which directly stimulates the auditory nerve, thus bypassing the defective inner ear. Cochlear implants convert sound waves to electrical impulses and transmit them to the inner ear, providing people with the ability to hear sounds and potentially better understand speech without reading lips. Small implant, great results is the norm. The best results were found among children who received the cochlear implant at 0-3 years of age. They achieved 90 to 95 percent hearing and language improvement. 80-90 percent of these children develop a hearing and speech equal to those of children with normal hearing.
