navigation by reflected sound
a way some animals find things by listening to echoes
Schéma d’usage :
echolocation (in [animal])
Erreur fréquente :
Echolocation is not the same as simply having good hearing; it specifically involves using echoes from sounds that are produced.
Synonymes
biosonar (often used for echolocation in animals, especially marine mammals.)
Antonymes
vision (finding things by sight rather than by echoes.)
Collocations
bat echolocation
|dolphin echolocation
|use echolocation
|echolocation ability
|echolocation system
|echolocation calls
|echolocation pulses
|echolocation signals
|echolocation behavior
|navigate by echolocation
Thèmes

Exemples
- Bats rely on echolocation to avoid obstacles in the dark.
- Scientists recorded echolocation calls to study how dolphins hunt.
- The cave fish showed reduced vision but strong echolocation-like sensing.
Exemples pédagogiques
- Bats use echolocation at night.
- Echolocation helps dolphins find fish.

locating objects with sound echoes
a way to find objects by sending sound and listening to the echo
Schéma d’usage :
echolocation for [purpose]
Erreur fréquente :
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
Synonymes
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
Antonymes
radar (a different ranging method that uses radio waves instead of sound.)

Exemples
- The robot uses echolocation to map the corridor when the lights are off.
- Engineers tested echolocation methods for obstacle detection in drones.
- Echolocation can be effective underwater because sound travels well in water.
Exemples pédagogiques
- The device uses echolocation to find walls.
- Echolocation works by listening to echoes.

human navigation by clicking sounds
a way some people use echoes to know where things are
Schéma d’usage :
learn echolocation; use echolocation to [do something]
Erreur fréquente :
It does not mean using a machine; in this sense it can be a learned human skill.
Synonymes
click-based navigation (describes the common technique used in human echolocation.)
Antonymes
visual navigation (moving around mainly by using sight rather than echoes.)
Collocations

|learn echolocation
|echolocation training
|echolocation skills
|mouth clicks
|use clicks for echolocation
|echolocation in blind people
|practice echolocation
Thèmes

Exemples
- 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.
Exemples pédagogiques
- He learned echolocation to walk safely.
- She uses clicks for echolocation.

the act of echo-based detection
finding something by using echoes
Schéma d’usage :
echolocation of [object/area]
Erreur fréquente :
This is a broad sense; in many contexts it specifically refers to animals (especially bats and dolphins).
Synonymes
echo ranging (a general descriptive term for measuring location by echoes.)
Antonymes
direct observation (identifying something without relying on reflected sound.)
Collocations
the echolocation process
|echolocation of targets
|echolocation in darkness
|echolocation in water
|echolocation research
|echolocation study
Thèmes
science
|sound
Exemples
- Echolocation is an efficient way to detect objects when visibility is low.
- The lecture explained echolocation as a process of measuring time delays in echoes.
Exemples pédagogiques
- Echolocation uses echoes to detect objects.

active echolocation
1/ˈæktɪv ˌɛkoʊloʊkˈeɪʃən/
fixed phrase
technical
echolocation by making sounds
echolocation where you make the sound yourself
Exemples
- 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
Exemples
- 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
1/dˈɑlfən ˌɛkoʊloʊkˈeɪʃən/
fixed phrase
technical
echolocation used by dolphins
the way dolphins use clicks and echoes underwater
Exemples
- Dolphin echolocation is strong enough to detect fish hiding in sand.
- The team used underwater microphones to capture dolphin echolocation in the bay.
echolocation call
1/ˌɛkoʊloʊkˈeɪʃən kˈɔl/
fixed phrase
technical
sound used to create echoes
a sound an animal makes to hear echoes
Exemples
- The bat emitted an echolocation call just before it grabbed the moth.
- Different species have distinctive echolocation calls that can be identified in recordings.
passive echolocation

fixed phrase
technical
echo use without making sounds
finding things by listening to echoes of other sounds
Exemples
- Some researchers discuss passive echolocation in animals that exploit ambient noise.
- Passive echolocation can be harder because the sound source is not under the listener’s control.
