Sonograms of female copulatory vocalizations of a human female (top), female baboon (middle), and female gibbon (bottom), [19] with time being plotted on the x-axis and the pitch being represented on the y-axis. In non-human primates, copulatory vocalizations begin towards the end of the copulatory act or even after copulation. [2]
For example, many frogs may use trilling notes in mate attraction, but switch to different vocal patterns in aggressive territorial displays. [19] In some species, a single song incorporates several note types which serve different purposes, with one type of note eliciting responses from females, and another note of the same song responsible ...
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 ...
More important than range in voice classification is tessitura, or where the voice is most comfortable singing, and vocal timbre, or the characteristic sound of the singing voice. [1] For example, a female singer may have a vocal range that encompasses the low notes of a mezzo-soprano and the high notes of a soprano. A voice teacher would ...
The sound of each individual's voice is thought to be entirely unique [13] not only because of the actual shape and size of an individual's vocal cords but also due to the size and shape of the rest of that person's body, especially the vocal tract, and the manner in which the speech sounds are habitually formed and articulated. (It is this ...
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.

The sounds produced by male midshipman fish cause reproductive females to develop a hormone-mediated selective sensitivity to this sound, and they respond by laying eggs in the rock nest of a singing male. This selective sensitivity to higher frequency correlates to increased levels of testosterone and estradiol. [11]
