navigation by reflected sound
a way some animals find things by listening to echoes
نمط الاستخدام:
echolocation (in [animal])
غلطة شائعة:
Echolocation is not the same as simply having good hearing; it specifically involves using echoes from sounds that are produced.
مرادفات
biosonar (often used for echolocation in animals, especially marine mammals.)
أضداد
vision (finding things by sight rather than by echoes.)

أمثلة
- 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.
أمثلة للمتعلمين

locating objects with sound echoes
a way to find objects by sending sound and listening to the echo
نمط الاستخدام:
echolocation for [purpose]
غلطة شائعة:
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
مرادفات
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
أضداد
radar (a different ranging method that uses radio waves instead of sound.)

أمثلة
- 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.
أمثلة للمتعلمين
- 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
نمط الاستخدام:
learn echolocation; use echolocation to [do something]
غلطة شائعة:
It does not mean using a machine; in this sense it can be a learned human skill.
مرادفات
click-based navigation (describes the common technique used in human echolocation.)
أضداد
visual navigation (moving around mainly by using sight rather than echoes.)

أمثلة
- 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.
أمثلة للمتعلمين
- He learned echolocation to walk safely.
- She uses clicks for echolocation.

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

|echolocation of targets
|echolocation in darkness
|echolocation in water

أمثلة
- 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.
أمثلة للمتعلمين
- Echolocation uses echoes to detect objects.

fixed phrase
technical
echolocation by making sounds
echolocation where you make the sound yourself
أمثلة
- 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
أمثلة
- 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
أمثلة
- Dolphin echolocation is strong enough to detect fish hiding in sand.

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