Alec Nevala-Lee's "The Whale God" (novelette): Subaudible sound as a military weapon

Main idea has been used in fiction for decades: sounds with frequency below the human hearing threshold, while inaudible, still make people uncomfortable.

Here, US military is testing it during Vietnam War as a possible weapon. Only problem is: they're using it off a ship, & targeting the sound at coast. Not only are a lot of non-combatants affected, it's also affecting the whales in the ocean.

In fact, much of the story is about attempts to refloat whales that wash ashore as a result of their senses getting confused because of these subvocal sounds.
