In 2004, pediatric audiologist Allyson Sisler-Dinwiddie plunged into a world of silence after a car accident damaged her hearing. Under the care of hearing researcher Rene Gifford, she became one of the first test subjects of a new technique to improve cochlear implants, devices that use electrodes to stimulate cells in the inner ear. Since then, Sisler-Dinwiddie and Gifford have worked together to restore other patients’ hearing. Watch the pair and their team at Vanderbilt University as they develop a resounding remedy to help people hear again.
