Question

Quizplus · Accepted Answer

Echolocation can be accomplished by clicking one's tongue, as well as making other sounds to navigate and perceive the environment. It is not necessarily a skill that is only obtainable by people who are blind, nor does it inherently make someone with blindness more adept at using their hearing. There is also no evidence that practicing echolocation allows humans to hear higher frequencies.
