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

the act of echo-based detection
finding something by using echoes
الگوی کاربرد:
echolocation of [object/area]
اشتباه رایج:
This is a broad sense; in many contexts it specifically refers to animals (especially bats and dolphins).
هممعنیها
echo ranging (a general descriptive term for measuring location by echoes.)
متضادها
direct observation (identifying something without relying on reflected sound.)
ترکیبهای رایج

|echolocation of targets
|echolocation in darkness
|echolocation in water
|echolocation research
|echolocation study
