Human echolocation is the ability of humans to detect objects in their environment by sensing echoes from those objects. This ability is used by some blind people to navigate within their environment. They actively create sounds, such as by tapping their canes, lightly stomping their foot or by making clicking noises with their mouths. It can however also be fed in to the human nervous system as a new sensory experience. Human echolocation is similar in principle to active sonar and to the animal echolocation employed by some animals, including bats and dolphins.

Ben Underwood had this ability. Unfortunately, he is no more with us. Check out the below documentary on him. Give some time watch it and you won’t regret.
