People who have severe to profound hearing loss may want to consider cochlear implants. The electronic device—surgically implanted under the skin behind the ear—is designed to stimulate nerves inside the inner ear to enhance hearing sensation, essentially reinventing the way you hear.

A second component containing a microphone, sound processor and transmitter is worn externally. Users must be trained to understand speech through the transplant, which can take up to a year.

Hearing Loss: On the Horizon

Scientists are working to improve hearing aids and find ways to make them more accessible. At Johns Hopkins, Dr. Lin and his colleagues are recruiting participants for a future study to better understand how hearing aids and cochlear implants affect the lives of adults with hearing loss.
