  2. Hearing range - Wikipedia

    en.wikipedia.org/wiki/Hearing_range

    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 frequencies, and a gradual loss of sensitivity to higher frequencies ...

    The frequency range of dog hearing is approximately 40 Hz to 60,000 Hz, which means that dogs can detect sounds far beyond the upper limit of the human auditory spectrum.

    Key Takeaways: Human hearing spans from 20 Hz to 20,000 Hz. Hearing conversation in noise is challenging, especially when the noise has a similar frequency to human speech.

    en.wikipedia.org/wiki/Dog_whistle

    The top end of a dog's hearing range is about 45 kHz, while a cat's is 64 kHz. [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]

  7. Ultrasound - Wikipedia

    en.wikipedia.org/wiki/Ultrasound

    Dogs and cats' hearing range extends into the ultrasound; the top end of a dog's hearing range is about 45 kHz, while a cat's is 64 kHz. [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]

  8. Bioacoustics - Wikipedia

    en.wikipedia.org/wiki/Bioacoustics

    The examples include ground vibrations produced by elephants whose principal frequency component is around 15 Hz, and low- to medium-frequency substrate-borne vibrations used by most insect orders. [14] Many animal sounds, however, do fall within the frequency range detectable by a human ear, between 20 and 20,000 Hz. [15]

  9. Hearing - Wikipedia

    en.wikipedia.org/wiki/Hearing

    A cat can hear high-frequency sounds up to two octaves higher than a human. Not all sounds are normally audible to all animals. Each species has a range of normal hearing for both amplitude and frequency. Many animals use sound to communicate with each other, and hearing in these species is particularly important for survival and reproduction.
