Not to get too deep in the underwater weeds here but sound propagation underwater is not omnidirectional like how sound propagates above water. And I’m not sure how true that is either

All that to say, I certainly understand the concern. But I would personally have to see evidence of harm

For underwater acoustic systems there is a well understood and effective marine mammal mitigation process that’s followed. Basically, slowly stepping up in power. Not sure if they’re employing that here but if it involves NATO, I would expect that’s being employed
