When Derrick Coleman was growing up, kids called him "Four Ears." He couldn't hide his bulky hearing aids, and he could not hear without them. So he drowned out the bullies and focused on the one thing he felt leveled the playing field: football. Coleman became a Super Bowl champion with the Seattle Seahawks. Vital Signs explore the most common sensory disorder, hearing loss, which affects 360 million people worldwide. From revolutionary research about the brain's relationship with sign language, to the next generation of hearing implants for children, see how people around the world are breaking down the sound barrier.
