Sonograms of female copulatory vocalizations of a human female (top), female baboon (middle), and female gibbon (bottom), [19] with time being plotted on the x-axis and the pitch being represented on the y-axis. In non-human primates, copulatory vocalizations begin towards the end of the copulatory act or even after copulation. [2]
For each action potential fired in their vocal pattern generator, there is exactly one sonic motor neuron that fires, and there is exactly one sound pulse. [12] The two motor nuclei fire in phase in toadfish, leading to the paired contraction of the sonic muscles. [13] The duration of calls is controlled by the pre-pacemaker neurons in the ...
Toothed whales (odontocetes) pass air through a system of air sacs and muscular phonic lips, which vibrate to produce audible vocalizations, thus serving the function of vocal folds in other mammals. [4] Sound vibrations are conveyed to an organ in the head called the melon, which can be changed in shape to control and direct vocalizations. [5]
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 .
Vocal learning is the ability to modify acoustic and syntactic sounds, acquire new sounds via imitation, and produce vocalizations. "Vocalizations" in this case refers only to sounds generated by the vocal organ (mammalian larynx or avian syrinx ) as opposed to by the lips, teeth, and tongue, which require substantially less motor control.

The vocal folds are long and are attached close to the epiglottis base. When comparing an elephant's vocal folds to those of a human, an elephant's are longer, thicker, and have a larger cross-sectional area. In addition, they are tilted at 45 degrees and positioned more anteriorly than a human's vocal folds. [18]
Only the male frogs are able to produce mating calls to attract gravid female frogs. When male and non-gravid female frogs are clasped by sexually active male frogs, they produce a release call. In the leopard frog, there are three movements for their sound production. First, there are body wall contradictions to serve as a way for the intra ...
In underwater acoustics and fisheries acoustics the term is also used to mean the effect of plants and animals on sound propagated underwater, usually in reference to the use of sonar technology for biomass estimation. [2] [3] The study of substrate-borne vibrations used by animals is considered by some a distinct field called biotremology. [4]
