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

Παραδείγματα
- After months of practice, he used echolocation to move confidently through unfamiliar rooms.
- The documentary showed how echolocation can help some blind people judge distance.
- She made small clicks and listened for changes in the echo as part of her echolocation routine.
Παραδείγματα για μαθητές

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

fixed phrase
technical
echolocation by making sounds
echolocation where you make the sound yourself
Παραδείγματα
- Bats use active echolocation by emitting calls and listening for echoes.
- The paper compared active echolocation with other sensory strategies in nocturnal animals.
bat echolocation
1/bˈæt ˌɛkoʊloʊkˈeɪʃən/
fixed phrase
technical
echolocation used by bats
the way bats use echoes to find things
Παραδείγματα
- Researchers analyzed bat echolocation to understand how bats track fast-moving insects.
- Bat echolocation changes depending on whether the bat is in open air or near trees.
dolphin echolocation

fixed phrase
technical
echolocation used by dolphins
the way dolphins use clicks and echoes underwater
Παραδείγματα

echolocation call
1/ˌɛkoʊloʊkˈeɪʃən kˈɔl/
fixed phrase
technical
sound used to create echoes
a sound an animal makes to hear echoes
Παραδείγματα
