navigation by reflected sound
a way some animals find things by listening to echoes
Mẫu sử dụng:
echolocation (in [animal])
Lỗi thường gặp:

Từ đồng nghĩa
biosonar (often used for echolocation in animals, especially marine mammals.)
Từ trái nghĩa
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
Mẫu sử dụng:
echolocation for [purpose]
Lỗi thường gặp:
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
Từ đồng nghĩa
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
Từ trái nghĩa
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
Mẫu sử dụng:
learn echolocation; use echolocation to [do something]
Lỗi thường gặp:
It does not mean using a machine; in this sense it can be a learned human skill.
Từ đồng nghĩa
click-based navigation (describes the common technique used in human echolocation.)
Từ trái nghĩa
visual navigation (moving around mainly by using sight rather than echoes.)
