Multiple Choice

Which term describes the process of using reflected sound waves to locate objects, such as bats use?

Echolocation is the process of using reflected sound waves to locate objects, just as bats do. When a sound is emitted, the returning echoes provide information about how far away an object is, its size, texture, and position in space. In orientation and mobility practice, some individuals learn to use echolocation by producing sounds (like clicks) and interpreting the echoes to navigate and avoid obstacles. This clearly differs from simply determining where a sound is coming from, which relies on direct sound localization cues rather than echoed information, and from unrelated concepts like a hearing loss in one ear or psychosocial phases of adjustment to blindness.
