Most other whales and dolphins produce sounds of varying degrees of complexity. Of particular interest is the Beluga (the "sea canary") which produces an immense variety of whistles, clicks and pulses. [22] [23] It was previously thought that most baleen whales make sounds at about 15–20 hertz. [24]
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.
Amphibians like frogs and toads can vocalise using vibrating tissues in airflow. For example, frogs use vocal sacs and an air-recycling system to make sound, while pipid frogs use laryngeal muscles to produce an implosion of air and create clicking noise. [7] Aquatic mammals such as seals and otters can produce sound using the larynx.
As with other oceanic dolphins, dusky dolphins produce three basic sounds; echolocative click trains, burst pulses and tonal whistles. [ 39 ] [ 40 ] : 77 Their echolocation signals are quick and broadband , much like in other whistle-producing species, [ 40 ] : 95 and have two peaks; between 40 and 50 kHz at low frequency and between 80 and 110 ...
For the first time, researchers claim to have recorded a pair of dolphins demonstrating some rather human-like behavior. Dolphins might have a 'highly developed spoken language' Skip to main content
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 ...
Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or ...
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.
