Neuroimaging has shown that the processing of echoes activates brain regions in blind echolocators that would normally support vision in the sighted brain, and that the patterns of these activations are modulated by the information carried by the echoes. It is clear that echolocation may enable some blind people to do things that are otherwise thought to be impossible without vision, potentially providing them with a high degree of independence in their daily lives and demonstrating that echolocation can serve as an effective mobility strategy in the blind. Blind echolocation experts can sense small differences in the location of objects, differentiate between objects of various sizes and shapes, and even between objects made of different materials, just by listening to the reflected echoes from mouth clicks.

What is not as well-known is that some blind people have learned to do the same thing, making mouth clicks, for example, and using the returning echoes from those clicks to sense obstacles and objects of interest in their surroundings. ![]() a sound heard again near its source after being reflected. a repetition of sound produced by the reflection of sound waves from a wall, mountain, or other obstructing surface. They emit bursts of sounds and listen to the echoes that bounce back to detect the objects in their environment. (ekou) (noun plural echoes, verb echoed, echoing) noun. Bats and dolphins are known for their ability to use echolocation. The sound waves left your mouth, traveled through the air, hit a hard surface, such as a wall, and then bounced back again, causing you to hear the sound again.
