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 .
For a long time humans have employed animal sounds to recognise and find them. Bioacoustics as a scientific discipline was established by the Slovene biologist Ivan Regen who began systematically to study insect sounds. In 1925 he used a special stridulatory device to play in a duet with an insect.
Some cicadas produce sounds louder than 106 dB (SPL), among the loudest of all insect-produced sounds. [2] They modulate their noise by positioning their abdomens toward or away from the substrate. The sound of an Amphipsalta zelandica cicada in Lower Hutt , New Zealand , recorded in mid-February, 2006
Tympanal organ on the tibia of the katydid Zabalius aridus Tympanal organ of two species of moths, ventral view of abdomen (Tineidae and Pyralidae). A tympanal organ (or tympanic organ) is a hearing organ in insects, consisting of a tympanal membrane stretched across a frame backed by an air sac and associated sensory neurons. [1]
Insects that produce sound can generally hear it. Most insects can hear only a narrow range of frequencies related to the frequency of the sounds they can produce. Mosquitoes can hear up to 2 kilohertz. [90] Certain predatory and parasitic insects can detect the characteristic sounds made by their prey or hosts, respectively.
The anatomical parts used to produce sound are quite varied: the most common system is that seen in grasshoppers and many other insects, where a hind leg scraper is rubbed against the adjacent forewing (in beetles and true bugs the forewings are hardened); in crickets and katydids a file on one wing is rubbed by a scraper on the other wing; in ...

Two examples of near-field sound communication are bee's waggle dance and Drosophila courtship songs. [12] In fruit flies, the arista of the antennae and the third segment act as the sound receiver. [12] Vibrations of the receiver cause rotation of the third segment, which channels sound input to the mechanoreceptors of the Johnston's organ. [12]
