Як далеко чути спів блакитного кита? | How far can a blue whale call travel?

A blue whale’s low-frequency song can travel a long way underwater. Source levels of some calls have been reported at up to about 188 decibels referenced to 1 micropascal at 1 metre. Under favorable conditions, propagation models have estimated detection ranges as far as 800 kilometres, but that does not mean every call can be heard at that distance: noise, depth, seafloor shape, and call type all matter.
