navigation by reflected sound

a way some animals find things by listening to echoes

نمط الاستخدام: echolocation (in [animal])
خطأ شائع:
Echolocation is not the same as simply having good hearing; it specifically involves using echoes from sounds that are produced.
المرادفات
biosonar (often used for echolocation in animals, especially marine mammals.)
الأضداد
vision (finding things by sight rather than by echoes.)
المتلازمات اللفظية
bat echolocation |dolphin echolocation |use echolocation |echolocation ability |echolocation system |echolocation calls |echolocation pulses |echolocation signals |echolocation behavior |navigate by echolocation
الموضوعات
animals |biology |senses |nature
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 للمتعلّمين
  • 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

نمط الاستخدام: echolocation for [purpose]
خطأ شائع:
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
المرادفات
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
الأضداد
radar (a different ranging method that uses radio waves instead of sound.)
المتلازمات اللفظية
echolocation technique |echolocation method |echolocation-based navigation |echolocation algorithm |echolocation sensor |echolocation experiment |echolocation data |echolocation mapping |underwater echolocation |echolocation signal processing
الموضوعات

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 للمتعلّمين
  • 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]
خطأ شائع:
It does not mean using a machine; in this sense it can be a learned human skill.
المرادفات
click-based navigation (describes the common technique used in human echolocation.)
الأضداد
visual navigation (moving around mainly by using sight rather than echoes.)
المتلازمات اللفظية
human echolocation |learn echolocation |echolocation training |echolocation skills |mouth clicks |use clicks for echolocation |echolocation in blind people |practice echolocation
الموضوعات

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 للمتعلّمين
  • 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]
خطأ شائع:
This is a broad sense; in many contexts it specifically refers to animals (especially bats and dolphins).
المرادفات
echo ranging (a general descriptive term for measuring location by echoes.)
الأضداد
direct observation (identifying something without relying on reflected sound.)
المتلازمات اللفظية
the echolocation process |echolocation of targets |echolocation in darkness |echolocation in water |echolocation research |echolocation study
الموضوعات
science |sound
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 للمتعلّمين
  • Echolocation uses echoes to detect objects.

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.

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.
  • 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

أمثلة
