Grayson Clamp was born deaf. Three weeks ago, the toddler underwent a auditory brain implant that would allow him to hear. He had procedures in the past, but they all failed. Clamp was the first child in the U.S. to have the surgery and now we have touching video of the very first time he heard his father’s voice. You can tell that the boy successfully heard the voice and now his brain is re-working itself to be able to use sound. Hopefully the surgery could be used to treat many other people who are born deaf. Watch the touching video below.
