Can echolocation help those with vision loss?

A 10-week training program showed that both sighted and blind participants improved on echolocation tasks, with some even performing better than expert echolocators. The study's findings suggest that click-based echolocation can be a valuable tool for people with vision loss or progressive degenerative eye conditions.
