Yeah - I'm not sure how well the usual ear protections work in dense water.

Question as I am physics illiterate. Would the 'sound' from this have carried as far in water vs. in air? I ask because my assumption (which is ex recto, at best) is that the water disturbance we see is the extent to which the 'sound' traveled in the water. Or would the sound still travel without making a visible impact in the water, and still be loud enough to be a 'pain', so to speak?

Water will carry sound much further than air, because water is so much denser than air. So, here, instead of a few gaseous air molecules knocking against your eardrums, you'd have a fuckton more incompressible liquid water molecules knocking against your eardrums.

Consider that whales communicate with each other across thousands of miles.
