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, [ 3 ] [ 4 ] [ note 1 ] although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to ...
For animals with a larger head than humans the evaluation range for interaural phase differences is shifted towards lower frequencies, for animals with a smaller head, this range is shifted towards higher frequencies. The lowest frequency which can be localized depends on the ear distance. Animals with a greater ear distance can localize lower ...
By contrast, the average best frequency for animal hearing is 9.8 kHz, the average upper limit is 55 kHz. [10] The ability to differentiate frequencies of two successive tones was also tested for this elephant using a similar conditioning paradigm. The elephant's responses were somewhat erratic, which is typical for mammals in this test. [10]
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.
Although sounds of such low frequency are too low for humans to hear as a pitch, these sound are heard as discrete pulses (like the 'popping' sound of an idling motorcycle). Whales, elephants and other animals can detect infrasound and use it to communicate. It can be used to detect volcanic eruptions and is used in some types of music. [35]
Infrasound arrays at monitoring station in Qaanaaq, Greenland.. Infrasound, sometimes referred to as low frequency sound or incorrectly subsonic (subsonic being a descriptor for "less than the speed of sound"), [1] describes sound waves with a frequency below the lower limit of human audibility (generally 20 Hz, as defined by the ANSI/ASA S1.1-2013 standard).

In space, no one can hear you scream -- but you may hear a knock. When he was alone in a spacecraft in 2003, astronaut Yang Liwei reportedly heard a "knock" despite being alone.
Some primitive animals with two ears and small brains can perceive 3D space and process sounds, although the process is not fully understood. Some animals experience difficulty in 3D sound location due to small head size. Additionally, the wavelength of communication sound may be much larger than their head diameter, as is the case with frogs.
