The larynx has been implicated in the production of ultrasonic vocalizations. [11] A constriction within a rat’s larynx is thought to be the source of their ultrasonic vocalizations. [11] As well, brain areas such as the medulla oblongata, the cortex, the amygdala, and the dorsal hippocampus, among others, play a role in 22-kHz calls ...
Researchers at the University of Washington School of Medicine have developed a software program that enlists artificial intelligence to decipher the ultrasonic vocalizations made by mice and rats ...
Male Alston's singing mouse (Scotinomys teguina) singing to female in estrus. S. teguina is often recognized for its unique vocalization behavior. Both males and females produce vocalizations which are characterized by singing bouts containing both sonic and ultrasonic elements.
High frequency ultrasonic vocalizations are important in rat communication and function to elicit approach behavior in the recipient. [11] The initial goal of research by Jaak Panksepp and Jeff Burgdorf was to track the biological origins of how the brain processes emotions and social behavior. They compared rat vocalizations during social ...
The mouse communicates with other members of its species via ultrasound. The manner in which a male and female communicate changes from a more aggressive style to a more affiliative style during the development of a pair bond, and the characteristics of their vocalizations can be used to predict the stability of the pair bond.

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 .
As dogs hear higher frequency sounds than humans, they have a different acoustic perception of the world. [24] Sounds that seem loud to humans often emit high-frequency tones that can scare away dogs. Whistles which emit ultrasonic sound, called dog whistles, are used in dog training, as a dog will respond much better to such levels. In the ...
