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 .
[1] Twenty-two-kHz calls have been studied in pharmacology. The possible ways in which drugs affect 22-kHz vocalizations has been an area of particular interest, and it has been shown that administering certain benzodiazepines can lead to a reduction in calling behaviour, while certain antidepressants , dopamine reuptake inhibitors , and ...

The 2006 study also investigated the comfortable listening level (CLL) of music with and without HFCs, an alternative way of measuring subject response to the sound. The CLL for the music with HFCs was higher than that for the music without HFCs - this provides a quantitative way to demonstrate general listener preference for the music with ...
Biomusic can take many other forms. These can include the simple amplification of animal sounds, or the creation of music through the fluctuation of electric current in plants. More unusual still is the use of animal notation: music scores created by animals, often in the form of paw prints. Biomusic can also take the form of animals trained to ...
Due to the wide range of signal properties and media they propagate through, specialized equipment may be required instead of the usual microphone, such as a hydrophone (for underwater sounds), detectors of ultrasound (very high-frequency sounds) or infrasound (very low-frequency sounds), or a laser vibrometer (substrate-borne vibrational signals).
Sound from ultrasound is the name given here to the generation of audible sound from modulated ultrasound without using an active receiver. This happens when the modulated ultrasound passes through a nonlinear medium which acts, intentionally or unintentionally, as a demodulator .
The study of such sound waves is sometimes referred to as infrasonics, covering sounds beneath 20 Hz down to 0.1 Hz (and rarely to 0.001 Hz). People use this frequency range for monitoring earthquakes and volcanoes, charting rock and petroleum formations below the earth, and also in ballistocardiography and seismocardiography to study the ...
