navigation by reflected sound
a way some animals find things by listening to echoes
Schemat użycia:
echolocation (in [animal])
Częsty błąd:
Echolocation is not the same as simply having good hearing; it specifically involves using echoes from sounds that are produced.
Synonimy
biosonar (often used for echolocation in animals, especially marine mammals.)
Antonimy
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
Schemat użycia:
echolocation for [purpose]
Częsty błąd:
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
Synonimy
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
Antonimy
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
Schemat użycia:
learn echolocation; use echolocation to [do something]
Częsty błąd:
It does not mean using a machine; in this sense it can be a learned human skill.
Synonimy
click-based navigation (describes the common technique used in human echolocation.)
Antonimy
visual navigation (moving around mainly by using sight rather than echoes.)

Częsty błąd:
