"When you think of echolocation, you probably think of bats or dolphins. But echolocation has also been used as a way for blind people to navigate, too. Despite the skill’s usefulness, few blind people have actually learned how to use echolocation. Now, though, researchers say humans can learn echolocation in as little as 10 weeks. Which could make it a viable skill for people with vision impairments.
