The blue whale call recorded off Madagascar, a two‐unit phrase, [12] starts with 5–7 pulses with a center frequency of 35.1 ± 0.7 Hz and duration of 4.4 ± 0.5 s followed by a 35 ± 0 Hz tone lasting 10.9 ± 1.1 s. [11]
In 2009, researchers found that blue whale song has been deepening in its tonal frequency since the 1960s. [19] While noise pollution has increased ambient ocean noise by over 12 decibels since the mid-20th century, researcher Mark McDonald indicated that higher pitches would be expected if the whales were straining to be heard.
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 ...

An underwater photographer who got up close and personal with a massive blue whale says the experience left him feeling awestruck — and incredibly small. Stunning photo shows diver's close ...
Before extensive research on whale vocalizations was completed, the low-frequency pulses emitted by some species of whales were often not correctly attributed to them. Dr Payne wrote: "Before it was shown that fin whales were the cause [of powerful sounds], no one could take seriously the idea that such regular, loud, low, and relatively pure frequency tones were coming from within the ocean ...
