In 2003, NRDC spearheaded a successful lawsuit against the Navy to restrict the use of low-frequency sonar off the coast of California. Two years later a coalition of green groups led by NRDC and including the International Fund for Animal Welfare (IFAW), the League for Coastal Protection, Cetacean Society International, and Ocean Futures Society upped the ante, asking the federal courts to also restrict testing of more intense, harmful and far ranging mid-frequency types of sonar off Southern California’s coastline.
In filing their brief, the groups cited Navy documents which estimated that such testing would kill some 170,000 marine mammals and cause permanent injury to more than 500 whales, not to mention temporary deafness for at least 8,000 others.
And that's only just from testing off the coast of california.
I think it's interesting that sperm whales have a similar dynamic. Researchers need to get close to them to take recordings, but their calls are in the 230 decibel range where sound becomes a physical pressure wave.

sufficiently powerful sonar will make a human body explode military sonar hits in the 200+ decibel range and will destroy a person

Now imagine that we're doing this all the time all over the world's oceans and suddenly it makes sense why orcas are attacking yachts

not really as sailing yachts don't have sonar
they're just skipping the middle men
They are using yachts as practice before they can take on Nuclear-Powered Fleet Ballistic Missile Submarines

Whale calls can get loud enough to liquefy your organs but I agree

Maybe the whales possess those lost nuclear subs that were never found.
Huh?

ah
