  2. Hearing range - Wikipedia

    en.wikipedia.org/wiki/Hearing_range

    Logarithmic chart of the hearing ranges of some animals [1] [2] Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high ...

  3. Animal echolocation - Wikipedia

    en.wikipedia.org/wiki/Animal_echolocation

    Bat call frequencies range from as low as 11 kHz to as high as 212 kHz. [20] Insectivorous aerial-hawking bats, those that chase prey in the open air, have a call frequency between 20 kHz and 60 kHz, because it is the frequency that gives the best range and image acuity and makes them less conspicuous to insects. [21]

  4. Supersonus - Wikipedia

    en.wikipedia.org/wiki/Supersonus

    The typical frequency range for male katydid calls is between 5 kHz and 30 kHz, mostly within the human hearing range of 50 Hz to 20 kHz. The mating call of male S. aequoreus is the highest ultrasound calling carrier recorded in nature with a top frequency of 150 kHz. [1]

  5. 52-hertz whale - Wikipedia

    en.wikipedia.org/wiki/52-hertz_whale

    The 52-hertz whale, colloquially referred to as 52 Blue, is an individual whale of unidentified species that calls at the unusual frequency of 52 hertz. This pitch is at a higher frequency than that of the other whale species with migration patterns most closely resembling the 52-hertz whale's [ 1 ] – the blue whale (10 to 39 Hz) [ 2 ] and ...

  6. Dog whistle - Wikipedia

    en.wikipedia.org/wiki/Dog_whistle

    [3] [4] It is thought that the wild ancestors of cats and dogs evolved this higher hearing range in order to hear high-frequency sounds made by their preferred prey, small rodents. [3] The frequency of most dog whistles is within the range of 23 to 54 kHz, [ 5 ] so they are above the range of human hearing, although some are adjustable down ...

  7. Primate - Wikipedia

    en.wikipedia.org/wiki/Primate

    The Philippine tarsier, has a high-frequency limit of auditory sensitivity of approximately 91 kHz with a dominant frequency of 70 kHz, among the highest recorded for any terrestrial mammal.

  8. Ultrasound - Wikipedia

    en.wikipedia.org/wiki/Ultrasound

    [23] [24] The wild ancestors of cats and dogs evolved this higher hearing range to hear high-frequency sounds made by their preferred prey, small rodents. [23] A dog whistle is a whistle that emits ultrasound, used for training and calling dogs. The frequency of most dog whistles is within the range of 23 to 54 kHz. [25]

  9. Audio frequency - Wikipedia

    en.wikipedia.org/wiki/Audio_frequency

    An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
