  2. Human echolocation - Wikipedia

    en.wikipedia.org/wiki/Human_echolocation

    Human echolocation is the ability of humans to detect objects in their environment by sensing echoes from those objects, by actively creating sounds: for example, by tapping their canes, lightly stomping their foot, snapping their fingers, or making clicking noises with their mouths.

  3. Animal echolocation - Wikipedia

    en.wikipedia.org/wiki/Animal_echolocation

    The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...

  4. Pygmy swiftlet - Wikipedia

    en.wikipedia.org/wiki/Pygmy_Swiftlet

    Ebird describes this species " A tiny, common swiftlet found over lowland forest. Gray below with a paler belly, a darker throat, and dark patches on the underside of the base of the forewing. Black above with a distinctive white band on the rump. Tail square, and dark under the base. Nests in caves, where it uses echolocation.

  5. Southeastern long-eared bat - Wikipedia

    en.wikipedia.org/wiki/Southeastern_long-eared_bat

    These echolocation calls are sent out either through the mouth or the nostrils and the calls rebound back from the nearby objects and the bat's sensitive ears sense the echoes of their calls. [11] The bat's brain converts these faint echoes into information about the distance, size and texture of the nearby objects. [ 11 ]

  6. Ultrasound avoidance - Wikipedia

    en.wikipedia.org/wiki/Ultrasound_avoidance

    Ultrasound avoidance is an escape or avoidance reflex displayed by certain animal species that are preyed upon by echolocating predators. [1] Ultrasound avoidance is known for several groups of insects that have independently evolved mechanisms for ultrasonic hearing.

  7. Echolocation - Wikipedia

    en.wikipedia.org/wiki/Echolocation

    Animal echolocation, non-human animals emitting sound waves and listening to the echo in order to locate objects or navigate. Human echolocation, the use of sound by people to navigate. Sonar (sound navigation and ranging), the use of sound on water or underwater, to navigate or to locate other watercraft, usually by submarines.

  8. Bat - Wikipedia

    en.wikipedia.org/wiki/Bat

    Principle of bat echolocation: orange is the call and green is the echo. In low-duty cycle echolocation, bats can separate their calls and returning echoes by time. They have to time their short calls to finish before echoes return. [95] The delay of the returning echoes allows the bat to estimate the range to their prey. [93]

  9. Doppler shift compensation - Wikipedia

    en.wikipedia.org/wiki/Doppler_shift_compensation

    These types of echolocation pulses afford the bat the ability to classify, detect flutter (e.g. the fluttering wings of insects), and determine velocity information about the target. [5] Both CF and CF-FM bats use the Doppler shift compensation mechanism in order to maximize the efficiency of their echolocation behavior.
