navigation by reflected sound
a way some animals find things by listening to echoes
사용 패턴：
echolocation (in [animal])
자주 하는 실수：
Echolocation is not the same as simply having good hearing; it specifically involves using echoes from sounds that are produced.
유의어
biosonar (often used for echolocation in animals, especially marine mammals.)
반의어
vision (finding things by sight rather than by echoes.)

locating objects with sound echoes
a way to find objects by sending sound and listening to the echo
사용 패턴：
echolocation for [purpose]
자주 하는 실수：
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
유의어
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
반의어
radar (a different ranging method that uses radio waves instead of sound.)

human navigation by clicking sounds
a way some people use echoes to know where things are
사용 패턴：
learn echolocation; use echolocation to [do something]
자주 하는 실수：
It does not mean using a machine; in this sense it can be a learned human skill.
유의어
click-based navigation (describes the common technique used in human echolocation.)
반의어
visual navigation (moving around mainly by using sight rather than echoes.)
