I would love to meet this amazing blind kid!
After losing his eyes to cancer, Ben Underwood learned to use echolocation to find his way in the dark.
What is echolocation?
Echolocation means using sound to map out your surroundings.
Ben “sees” by making clicking sounds with his mouth. Those clicks bounce off the street, the walls, and the people nearby. The echoes from these clicks bounce back to Ben’s ear.
His brain interprets the sound waves, telling him how far away he is from the street, the wall, and the people.
