navigation by reflected sound
a way some animals find things by listening to echoes
Vzorec užití:
echolocation (in [animal])
Častá chyba:
Echolocation is not the same as simply having good hearing; it specifically involves using echoes from sounds that are produced.
Synonyma
biosonar (often used for echolocation in animals, especially marine mammals.)
Antonyma
vision (finding things by sight rather than by echoes.)
Kolokace
bat echolocation
|dolphin echolocation
|use echolocation
|echolocation ability
|echolocation system
|echolocation calls
|echolocation pulses
|echolocation signals
|echolocation behavior
|navigate by echolocation
Témata
animals
|biology
|senses
|nature
Příklady
- 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.
Učební příklady
- 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
Vzorec užití:
echolocation for [purpose]
Častá chyba:
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
Synonyma
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
Antonyma
radar (a different ranging method that uses radio waves instead of sound.)

|echolocation method
|echolocation-based navigation
|echolocation algorithm
|echolocation sensor
|echolocation experiment

|echolocation mapping
|underwater echolocation
|echolocation signal processing
Témata
science
|technology
|sound
|navigation
Příklady
- 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.
Učební příklady
- 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
Vzorec užití:
learn echolocation; use echolocation to [do something]
Častá chyba:
It does not mean using a machine; in this sense it can be a learned human skill.
Synonyma
click-based navigation (describes the common technique used in human echolocation.)
Antonyma
visual navigation (moving around mainly by using sight rather than echoes.)
Kolokace

Příklady
- 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.
Učební příklady
- He learned echolocation to walk safely.
- She uses clicks for echolocation.

the act of echo-based detection
finding something by using echoes
Vzorec užití:
echolocation of [object/area]
Častá chyba:
This is a broad sense; in many contexts it specifically refers to animals (especially bats and dolphins).
Synonyma
echo ranging (a general descriptive term for measuring location by echoes.)
Antonyma
direct observation (identifying something without relying on reflected sound.)
Kolokace
the echolocation process
|echolocation of targets
|echolocation in darkness
|echolocation in water
|echolocation research
|echolocation study
Témata
science
|sound
Příklady
- 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.
Učební příklady
