I think the original post is implying that something a little like hydrostatic shock (from air compression waves only, of course) is capable of causing hearing loss. I don’t know that to be false.
Counter-intuitively, the lower frequency “BOOM” causes more loss in the upper frequencies. The cochlea is shaped like a snail shell. The lower frequency booms pass by the first couple of the “snail’s” passageways until the hit the smaller, tighter passageways next to the skull bone. It’s in these smaller places that the hair cells detect higher frequencies and receive most of the damage from high-impact noises. I guess you could call that a type of hydrostatic shock. I don’t know.
