Scientists have been unable to explain this phenomenon. 52 Hz is a very low sound, it is audible through human ears as a low moaning sound. [25] It was not expected that this whale was a new species, more so this whale indicated that a currently known species potentially has a much wider vocal range than previously thought. [24]
The use of calls has led to proposals for splitting of species complexes such as those of the Mirafra bushlarks. [136] Smartphone apps can identify birds using sounds. [137] These apps work by comparing against spectrographic databases for matches.
The archosaurian shift from larynx to syrinx must have conferred a selective advantage for crown birds, but the causes for this shift remain unknown. [10] To complicate matters, the syrinx falls into an unusual category of functional evolution: arising from ancestors with a larynx-based sound source, the syrinx contains significant functional overlap with the structure it replaced.

Some species call while they are underwater and the sound travels through the water. This is adaptive in a region with many species competing for air time. Narins has found female frog species that use solid surfaces, such as blades of grass and logs, upon which they tap rhythmically to attract mates.
A purr or whirr is a tonal fluttering sound made by some species of felids, including both larger, outdoor cats and the domestic cat (Felis catus), as well as two species of genets. It varies in loudness and tone among species and in the same animal.
Many animals use sound to communicate with each other, and hearing in these species is particularly important for survival and reproduction. In species that use sound as a primary means of communication, hearing is typically most acute for the range of pitches produced in calls and speech.
Zoomusicology (/ ˌ z oʊ ə m j uː z ɪ ˈ k ɒ l ə dʒ i /) is the study of the musical aspects of sound and communication as produced and perceived by animals. [1] It is a field of musicology and zoology, and is a type of zoosemiotics.
