navigation by reflected sound

a way some animals find things by listening to echoes

biosonar (often used for echolocation in animals, especially marine mammals.)
対義語
vision (finding things by sight rather than by echoes.)
コロケーション
bat echolocation |dolphin echolocation |use echolocation |echolocation ability |echolocation system |echolocation calls |echolocation pulses |echolocation signals |echolocation behavior |navigate by echolocation
テーマ
animals |biology |senses |nature
例文
  • 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.
学習者向け例文

locating objects with sound echoes

a way to find objects by sending sound and listening to the echo

用法パターン: echolocation for [purpose]
よくある間違い:
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
類義語
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
対義語
radar (a different ranging method that uses radio waves instead of sound.)
コロケーション

テーマ
science |technology |sound |navigation
例文
  • 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.
学習者向け例文
  • 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

用法パターン: learn echolocation; use echolocation to [do something]
よくある間違い:
It does not mean using a machine; in this sense it can be a learned human skill.
類義語
click-based navigation (describes the common technique used in human echolocation.)
対義語
visual navigation (moving around mainly by using sight rather than echoes.)
コロケーション
human echolocation |learn echolocation |echolocation training |echolocation skills |mouth clicks |use clicks for echolocation |echolocation in blind people |practice echolocation
テーマ
health |disability |senses |daily_life
例文
  • 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.

the act of echo-based detection

finding something by using echoes

用法パターン: echolocation of [object/area]
よくある間違い:
This is a broad sense; in many contexts it specifically refers to animals (especially bats and dolphins).
類義語
echo ranging (a general descriptive term for measuring location by echoes.)
対義語
direct observation (identifying something without relying on reflected sound.)
コロケーション
the echolocation process |echolocation of targets |echolocation in darkness |echolocation in water |echolocation research |echolocation study
テーマ
