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).
Controlled exposure experiments, using simulated military sonar and other mid-frequency sounds, measured behavioral responses of tagged blue whales in feeding areas within the Southern California Bight. Despite using source levels orders of magnitude below some operational military systems, the results demonstrated that mid-frequency sound can ...
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. Humans produce sound by expelling air through the larynx.
It is one of Earth's most haunting sounds - the "singing" of baleen whales like the humpback, heard over vast distances in the watery realm. Baleen whales - a group that includes the blue whale ...
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 ...

He identified these sounds as whales singing to one another. [ 5 ] Payne's recordings were released in 1970 as an LP called Songs of the Humpback Whale (still the best-selling nature sound record of all time) [ 7 ] which helped to gain momentum for the Save the Whales movement seeking to end commercial whaling , which at the time was pushing ...
Exposure to simulated MFA sonar was found to interrupt blue whale deep-dive feeding, but no changes in behavior were observed in individuals feeding at shallower depths. The responses also depended on the animal's behavioral state, its (horizontal) distance from the sound source and the availability of prey. [160]
