[7] [8] [9] Because the calls have also been recorded from blue whale trios from in a putative reproductive context, it has been recently suggested that this call has different functions. [10] The blue whale call recorded off Sri Lanka is a three‐unit phrase. The first unit is a pulsive call ranging 19.8 to 43.5 Hz, lasting 17.9 ± 5.2 s.
Moreover, there is evidence that blue whales stop producing foraging D calls once a mid-frequency sonar is activated, even though the sonar frequency range (1–8 kHz) far exceeds their sound production range (25–100 Hz). [2] Voyager Golden Records carried whale songs into outer space with other sounds representing planet Earth.
Blue whale calls recorded off Sri Lanka have a three-unit phrase. The first unit is a 19.8 to 43.5 Hz pulsive call, and is normally 17.9 ± 5.2 seconds long.
Blue whales are known for their use of a variety of sounds (known as songs) including hums, squeaks, and rumbles to communicate with one another, particularly during the breeding season in winter.
The scientists examined the timing and frequency of 8,719 coda sequences — in solitary whale utterances, in choruses and in call-and-response exchanges between whales.
The 52-hertz whale, colloquially referred to as 52 Blue, is an individual whale of unidentified species that calls at the unusual frequency of 52 hertz. This pitch is at a higher frequency than that of the other whale species with migration patterns most closely resembling the 52-hertz whale's [ 1 ] – the blue whale (10 to 39 Hz) [ 2 ] and ...
While the audio profile of Bloop does resemble that of a living creature, [4] the source was a mystery both because it was different from known sounds and because it was several times louder than the loudest recorded animal, the blue whale. [5] The NOAA Vents Program has attributed Bloop to a large icequake. Numerous icequakes share similar ...
Like all marine mammals, sperm whales are very social animals, with their calls an integral part of this. The new study has provided a fuller understanding of how these whales communicate.
