Like other whales, the male fin whale has been observed to make long, loud, low-frequency sounds. [19]Most sounds are frequency-modulated (FM) down-swept infrasonic pulses from 16 to 40 hertz frequency (the range of sounds that most humans can hear falls between 20 hertz and 20 kilohertz).
It was not expected that this whale was a new species, more so this whale indicated that a currently known species potentially has a much wider vocal range than previously thought. [24] There is disagreement in the scientific community regarding the uniqueness of the whale's vocalization and whether it is a member of a hybrid whale such as the ...
Toothed whale (odontocete) vocal anatomy. Most mammalian species produce sound by passing air from the lungs across the larynx, vibrating the vocal folds. [3] Sound then enters the supralaryngeal vocal tract, which can be adjusted to produce various changes in sound output, providing refinement of vocalizations. [3]
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 ...
Whales: Two groups of whales, the humpback whale and a subspecies of blue whale found in the Indian Ocean, are known to produce repeated sounds at varying frequencies, known as whale songs. Male humpback whales perform these vocalizations only during the mating season, and so it is surmised the purpose of songs is to aid sexual selection ...
Still, uncovering the scope of whales’ vocal exchanges is an important step toward linking whale calls to specific messages or social behaviors, the scientists reported May 7 in the journal ...

Infrasound also may be used for long-distance communication, especially well documented in baleen whales (see whale vocalization), and African elephants. [26] The frequency of baleen whale sounds can range from 10 Hz to 31 kHz, [27] and that of elephant calls from 15 Hz to 35 Hz.
