CHARLOTTE, N.C. – A Charlotte boy who was born deaf heard his father’s voice for the first time with the help of a new medical device.

Grayson Clamp, 3, can now hear thanks to an “auditory brain stem implant.”

It uses a microchip implanted on Grayson’s brain to interpret sounds.

Three weeks ago, doctors in North Carolina gave him the device.

After it was implanted, little Grayson heard his dad say, “Daddy loves you,” for the first time.

His family will not soon forget their son’s reaction.
