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

דוגמאות
- Bats rely on echolocation to avoid obstacles in the dark.

locating objects with sound echoes
a way to find objects by sending sound and listening to the echo
תבנית שימוש:
echolocation for [purpose]
טעות נפוצה:
Learners often confuse echolocation with radar; radar uses radio waves, while echolocation uses sound.
מילים נרדפות
sonar (a broader term; echolocation is often used for biological or biomimetic sonar.)
הפכים
radar (a different ranging method that uses radio waves instead of sound.)

human navigation by clicking sounds
a way some people use echoes to know where things are
תבנית שימוש:
learn echolocation; use echolocation to [do something]
טעות נפוצה:
It does not mean using a machine; in this sense it can be a learned human skill.
מילים נרדפות
click-based navigation (describes the common technique used in human echolocation.)
הפכים
visual navigation (moving around mainly by using sight rather than echoes.)

the act of echo-based detection
finding something by using echoes
תבנית שימוש:
echolocation of [object/area]
טעות נפוצה:
This is a broad sense; in many contexts it specifically refers to animals (especially bats and dolphins).
מילים נרדפות
echo ranging (a general descriptive term for measuring location by echoes.)
הפכים
direct observation (identifying something without relying on reflected sound.)

fixed phrase
technical
sound used to create echoes
a sound an animal makes to hear echoes
דוגמאות
