  2. Animal echolocation - Wikipedia

    en.wikipedia.org/wiki/Animal_echolocation

    Echolocation, also called bio sonar, is a biological active sonar used by several animal groups, both in the air and underwater. Echolocating animals emit calls and listen to the echoes of those calls that return from various objects near them.

  4. Common noctule - Wikipedia

    en.wikipedia.org/wiki/Common_Noctule

    The common noctule uses two main calls for echolocation. The frequencies of the first are 26–47 kHz, have most energy at 27 kHz and an average duration of 11.5ms. [23] The frequency of the second call is 22–33 kHz, having most energy at 22 kHz and an average duration of 13.8ms. [23] [24] Common noctule in the Seeburgpark near Konstanz (Germany)

  5. Active sensory systems - Wikipedia

    en.wikipedia.org/wiki/Active_sensory_systems

    Examples include echolocation of bats and dolphins and insect antennae. Using self-generated energy allows more control over signal intensity, direction, timing and spectral characteristics. By contrast, passive sensory systems involve activation by ambient energy (that is, energy that is preexisting in the environment, rather than generated by ...

  7. Melon (cetacean) - Wikipedia

    en.wikipedia.org/wiki/Melon_(cetacean)

    The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...

  8. Microbat - Wikipedia

    en.wikipedia.org/wiki/Microbat

    Echolocation is the process where an animal produces a sound of certain wavelength, and then listens to and compares the reflected echoes to the original sound emitted. Bats use echolocation to form images of their surrounding environment and the organisms that inhabit it by eliciting ultrasonic waves via their larynx .

  9. Marine mammals and sonar - Wikipedia

    en.wikipedia.org/wiki/Marine_mammals_and_sonar

    Active sonar, the transmission equipment used on some ships to assist with submarine detection, is detrimental to the health and livelihood of some marine animals. [1] Research has recently shown that beaked and blue whales are sensitive to mid-frequency active sonar and move rapidly away from the source of the sonar, a response that disrupts ...
