sundsFish does sound rather dubious
what i have noticed as a regular thing is the topography of the beaches that have mass strandings.
they are large and shallow
i dont follow the anti-science "the whale didnt say so so it must not be true" chorus of idiots.
if sound & light pollution effects humans, then sound pollution will inevitably effect sonar based life forms even more.
it is simple logic & science.
unfortunately the science is held back by self interested litigious finger pointers attempting to pervert science from learning.
grouped in with monkey-see monkey-do band-wagon groupies.
or what else could it be?
anomalistic harmonic frequency correlative cascade of electro magnetic field resonance corresponding with a geological event.
that would be my gues
to put that in laymens terms for those unfamiliar with scientific words...
sound waves can bounce, they can also be increased as they bounce off different types of walls and materials.
structures like walls rooms and such like often have a harmonic frequency that creates a resonance(this is a sound wave that is increased by the type of wall, like a musical instrument has a sound box etc).
when the planets align and the earth magnetic fields are increased or decreased by(& in conjunctin with) solar wind you can get a highly increased field of electromagnetic fields.
as this happens, if a type of earth quake happens in the right place(like making a glass make a tone by running your finger around the edge) then it may acoustically increase the sound by many times(potential acoustic cascade effect created by electromagnetic fields)
