Final answer:
Cochlear implants can restore hearing in older adults with nonfunctional cochlea, improving communication and daily activities.
Step-by-step explanation:
The implications of cochlear implants for older adults are significant. Cochlear implants can restore hearing in individuals who have a nonfunctional cochlea. The implant consists of a microphone, a speech processor, and a transmitter that send electrical impulses to the auditory nerve, bypassing the damaged or nonfunctional parts of the ear. For older adults with hearing loss, cochlear implants can greatly improve their ability to communicate and engage in daily activities.
