The historical background of natural sounds as they have come to be defined, begins with the recording of a single bird, by Ludwig Koch, as early as 1889.Koch's efforts in the late 19th and early 20th centuries set the stage for the universal audio capture model of single-species—primarily birds at the outset—that subsumed all others during the first half of the 20th century and well into ...
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 .
This is an accepted version of this page This is the latest accepted revision, reviewed on 14 January 2025. This is a list of onomatopoeias, i.e. words that imitate, resemble, or suggest the source of the sound that they describe. For more information, see the linked articles. Human vocal sounds Achoo, Atishoo, the sound of a sneeze Ahem, a sound made to clear the throat or to draw attention ...
A spectrogram of the soundscape of Mount Rainier National Park in the United States. Highlighted areas show marmot, bird, insect and aircraft noises. Soundscape ecology is the study of the acoustic relationships between living organisms, human and other, and their environment, whether the organisms are marine or terrestrial.
Sound waves may be viewed using parabolic mirrors and objects that produce sound. [ 9 ] The energy carried by an oscillating sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter, and the kinetic energy ...
The multiple sounds odontocetes make are produced by passing air through a structure in the head called the phonic lips. [28] Biologically the structure is homologous to an upper lip located in the nasal cavity, but mechanistically the phonic lips act similarly to human vocal "cords " (vocal folds), which in humans are located in the larynx .
The learned nature of bird song as well as evidence of "dialect"-like local variations have support theories about the existence of avian culture. [ 111 ] [ 29 ] As mentioned above , bird song's dependence on learning was studied by Thorpe, who found that chaffinches raised in isolation from their first week of life produce highly abnormal and ...
A possible mechanism behind this is the activation of mechanoreceptors by sound waves, which causes a flux of Ca 2+ into the plant cell causing it to depolarize [11] Because of the specific frequencies produced by the pollinators’ wings, perhaps only a distinct amount of Ca 2+ enters the cell, which would ultimately determine the plant ...
