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).
Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .
Humpback whales may also make stand-alone sounds that do not form part of a song, particularly during courtship rituals. [15] Finally, humpbacks make a third class of sound called the feeding call. [citation needed] This is a long sound (5 to 10 s duration) of near constant frequency. Humpbacks generally feed cooperatively by gathering in ...
The study also showed that the whales' vocalizations fall within the same frequency range and ocean depths - down to about 330 feet (100 meters) - as human-made shipping noises, interfering with ...
The higher frequencies in this range are also used for echolocation and the lower frequencies are commonly associated with social interaction as the signals travel much farther distances. Marine mammals use vocalisations in many different ways. Dolphins communicate via clicks and whistles, and whales use low-frequency moans or pulse signals.
Before extensive research on whale vocalizations was completed, the low-frequency pulses emitted by some species of whales were often not correctly attributed to them. Dr Payne wrote: "Before it was shown that fin whales were the cause [of powerful sounds], no one could take seriously the idea that such regular, loud, low, and relatively pure frequency tones were coming from within the ocean ...
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 ...
