[WorldUrbanLegend] 52-hertz whale
The 52-Hertz whale, also known as the 52 Blue whale, is a whale of an unknown species that is known for emitting a unique sound at the frequency of 52 hertz. This frequency is much higher than the frequencies of the whale species most similar to it, such as the blue whale (10–39Hz) and the fin whale (20Hz). The sound of this whale has been consistently detected in various locations since the late 1980s, and it is currently known as the only individual emitting a sound at this frequency. However, it has never been directly observed, and its sound can only be detected using underwater acoustic sensors. This whale is often referred to as "the loneliest whale in the world," and since 2010, occasional records have been found of a second whale emitting sounds at the same frequency. Musically, the frequency of 52 Hertz corresponds to G#1, the 12th lowest key on a standard piano, or the position of the 4th finger on the lowest string (E1) of a double bass. The sound of the 52 Hertz ...
