This sounds so soothing

Sperm whales - killer sounds Humpback - singing Fin whale - statistical analysis!

This is so amazing. Why did you sped up the sounds? Would they be unrecognizable for us? And why did the whale stopped when it knew there was an earthquake? How did it even knew that ?

[@DorianMichaelsIII]

That is *exactly* why-- if the calls weren't sped up, all our puny human ears would hear is a lot of silence, or at most, barely anything at all; they speed it up so we can better hear the patterns of their calls. Whales at that size (fin whales are only exceeded in size by the largest of whales, or indeed, the largest of ANY Earth animal, the blue whale) call at around 16-40 hertz; the *lowest* sound that the human ear can typically detect unaided is around *20* hertz. So unsped up, if you could hear anything at ALL, it'd likely be very, very, VERY faint, and hard to make out anything distinct at all. (And if you think the fin whale's calls are low, the blue whale can call at an even *lower* frequency; even sped up, you STILL have to strain to hear one of them.)

@@DorianMichaelsIII Hey thanks for that explanation. 🙋‍♀️🐳💙

It felt the earthquake because of the way water carries sound, but I'm sure you know that by now lol. 😅

that sounds cool.

Where was this recorded? How close was the whale?
