What is echolocation?
To my understanding “Echolocation” is the use of sound waves to tell the distance between human and animals and any objects. Echolocation is mainly used by blind animals or human in many different ways. They can use echolocation to find their needs, for example food and water or to get away from dangerous objects or enemies.

It is a very big challenge to use echolocation but blind people have learned to trust themselves. Blind people and animal can use their senses to see instead.
