3-year-old boy hears for first time Updated: Saturday, August 3, 2013 | (NEWSCHANNEL 3) - Cameras were recording as a 3-year-old boy heard sound for the first time in his life.The boy, Grayson Clamp, was born completely deaf.This week, a new device that looks something like a headband is helping him hear the sounds of his parents' voices.Grayson was able to hear because of a microchip implanted into his brain.It's part of an FDA trial, and he's the first child in the United States to get the device.His parents are thrilled, but they say there's still a long way to go."We don't know exactly what it's like. We don't know exactly what he hears," said mother Nicole Clamp. "If he hears everything we hear, some of what we hear; his brain is still trying to organize itself to use sound."Grayson's parents believe his story will help a lot more children, as doctors improve on the technology.
