This is because periods with highest acoustic presence of Antarctic minke whales aligned with their breeding season at lower latitudes of the Antarctic Ocean. [5] Additionally, the bio-duck sound shared similar acoustic properties to a "pulse train" which is another call by minke whales believed to serve reproductive functions. [6]
The findings provide clues about the evolution of acoustic mechanisms, and from that, the evolution of animals that employ them. In underwater acoustics and fisheries acoustics the term is also used to mean the effect of plants and animals on sound propagated underwater, usually in reference to the use of sonar technology for biomass estimation.
The minke whale (/ ˈ m ɪ ŋ k i /), or lesser rorqual, is a species complex of baleen whale. [1] The two species of minke whale are the common (or northern) minke whale and the Antarctic (or southern) minke whale. [2]
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.
A collection of two sub-phrases is a phrase. A whale will typically repeat the same phrase over and over for two to four minutes. This is known as a theme. A collection of themes is known as a song. [12] The whale song will last up to 30 or so minutes, and will be repeated over and over again over the course of hours or even days. [12]
Whale vocalizations are the sounds made by whales to communicate. The word " song " is used in particular to describe the pattern of regular and predictable sounds made by some species of whales (notably the humpback and bowhead whales ) in a way that is reminiscent of human singing.
Rorquals (/ ˈ r ɔːr k w əl z /) are the largest group of baleen whales, comprising the family Balaenopteridae, which contains nine extant species in two genera.They include the largest known animal that has ever lived, the blue whale, which can reach 180 tonnes (200 short tons), and the fin whale, which reaches 120 tonnes (130 short tons); even the smallest of the group, the northern minke ...
The common minke whale or northern minke whale (Balaenoptera acutorostrata) is a species of minke whale within the suborder of baleen whales. It is the smallest species of the rorquals and the second smallest species of baleen whale. Although first ignored by whalers due to its small size and low oil yield, it began to be exploited by various ...
