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 .
Process in a dolphin echolocation: in green the sounds generated by the dolphin, in red from the fish. Idealized dolphin head showing the regions involved in sound production. This image was redrawn from Cranford (2000). Odontocetes produce rapid bursts of high-frequency clicks that are thought to be primarily for echolocation. Specialized ...
The first ever 3D prints of images contained in dolphin echolocation sounds have been produced—including one of a human being seen from a dolphin's point of view.
Animal sound collections, managed by museums of natural history and other institutions, are an important tool for systematic investigation of signals. Many effective automated methods involving signal processing, data mining, machine learning and artificial intelligence [ 10 ] techniques have been developed to detect and classify the ...
Whale vocalizations are the sounds made by whales to communicate. The word "song" is used in particular to describe the pattern of regular and predictable sounds made by some species of whales (notably the humpback and bowhead whales) in a way that is reminiscent of human singing. Humans produce sound by expelling air through the larynx.
In general, three different types of sounds are produced by dolphins (and many other toothed whales). These are echolocative click trains, burst pulses and tonal whistles. [38] Dusky dolphins produce all three sounds. [39]: 77 Their echolocation signals are quick and broadband, much like in other whistle-producing species.
Information is limited on how extensively vocalization is used between individuals. It is capable of performing whistles, but rarely does so, suggesting that the whistle is a spontaneous sound and not a form of communication. The Ganges river dolphin most typically makes echolocation sounds such as clicks, bursts, and twitters. [21]
Because dolphins generally live in groups, communication is necessary. Signal masking is when other similar sounds (conspecific sounds) interfere with the original sound. [39] In larger groups, individual whistle sounds are less prominent. Dolphins tend to travel in pods, sometimes of up to 600 members. [40]
