IMAGE DISTRIBUTED FOR UNC HEALTH CARE - Grayson Clamp, 3 of Charlotte, N.C., wears an auditory brain stem implant to hear while supplementing speech with sign language at the Carolina Center for Communicative Disorders Program facility in Durham, N.C., Friday, August 23, 2013. Grayson is one of the first children in the U.S. to receive an auditory brain stem implant as part of an FDA-approved investigational trial to help restore his hearing. Members of the American Cochlear Implant Alliance and the UNC Ear and Hearing Center of UNC Hospitals gave Senator Kay Hagan (D-N.C.) a tour of one of its listening enrichment facilities. The groups want to highlight North Carolina’s commitment to early detection and intervention of hearing loss in children. Joining the tour is Grayson and his parents. A video that captured Grayson hearing his father's voice for the first time has garnered more than 1 million views on YouTube. (Sara D. Davis/AP Images for UNC Health Care) less
