navigation by reflected sound

a way some animals find things by listening to echoes

รูปแบบการใช้: echolocation (in [animal])
ข้อผิดพลาดที่พบบ่อย:
Echolocation is not the same as simply having good hearing; it specifically involves using echoes from sounds that are produced.
คำพ้องความหมาย
biosonar (often used for echolocation in animals, especially marine mammals.)
คำตรงข้าม
vision (finding things by sight rather than by echoes.)
คำที่ใช้ร่วมกัน
bat echolocation |dolphin echolocation |use echolocation |echolocation ability |echolocation system |echolocation calls |echolocation pulses |echolocation signals |echolocation behavior |navigate by echolocation
หัวข้อ
animals |biology |senses |nature
ตัวอย่าง
  • 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.
ตัวอย่างสำหรับผู้เรียน
  • 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

รูปแบบการใช้: echolocation for [purpose]
ข้อผิดพลาดที่พบบ่อย:
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
คำพ้องความหมาย
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
คำตรงข้าม
radar (a different ranging method that uses radio waves instead of sound.)
คำที่ใช้ร่วมกัน
echolocation technique |echolocation method |echolocation-based navigation |echolocation algorithm |echolocation sensor |echolocation experiment |echolocation data |echolocation mapping |underwater echolocation |echolocation signal processing
หัวข้อ
science |technology |sound |navigation
ตัวอย่าง
  • 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.
ตัวอย่างสำหรับผู้เรียน
  • 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

รูปแบบการใช้: learn echolocation; use echolocation to [do something]
ข้อผิดพลาดที่พบบ่อย:
It does not mean using a machine; in this sense it can be a learned human skill.
คำพ้องความหมาย
click-based navigation (describes the common technique used in human echolocation.)
คำตรงข้าม
visual navigation (moving around mainly by using sight rather than echoes.)
คำที่ใช้ร่วมกัน
human echolocation |learn echolocation |echolocation training |echolocation skills |mouth clicks |use clicks for echolocation |echolocation in blind people |practice echolocation
หัวข้อ
health |disability |senses |daily_life
ตัวอย่าง
  • 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.
ตัวอย่างสำหรับผู้เรียน
  • He learned echolocation to walk safely.
  • She uses clicks for echolocation.

the act of echo-based detection

finding something by using echoes

รูปแบบการใช้: echolocation of [object/area]
ข้อผิดพลาดที่พบบ่อย:
This is a broad sense; in many contexts it specifically refers to animals (especially bats and dolphins).
คำพ้องความหมาย
echo ranging (a general descriptive term for measuring location by echoes.)
คำตรงข้าม
direct observation (identifying something without relying on reflected sound.)
คำที่ใช้ร่วมกัน
the echolocation process |echolocation of targets |echolocation in darkness |echolocation in water |echolocation research |echolocation study
หัวข้อ
science |sound
ตัวอย่าง
  • 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.
ตัวอย่างสำหรับผู้เรียน
  • Echolocation uses echoes to detect objects.
