Sound in Water - The Good, the Bad, and the Ugly

No this isn't about waterproof mp3 players (I'll save that for another day), it's about how sound can influence the body in water.

The pool I swim at is part of a YMCA that recently underwent a massive renovation - except for the pool (never the pool). Seems like the construction guys were drilling or pounding most every day for about a year since they extended the footprint of the building by two, thus having to dig into the limestone rock to create a place to start the foundation.

What's all this have to do with swimming? Well, when they were pounding and drilling, you could hear it through the water. And on the pounding days, I could literally feel it rumbling my rib cage (the bad). I joked with friends that it was like lithotriptsy - which is how calcified kidney stones are destroyed by sending shock waves through a tub of water (the good).

Since the way shock waves travel through water is common knowledge, I'm confused why there is such surprise by the media when dolphins and other sea creatures spaz out where there are ocean shocks (the ugly) - think volcanic explosions, sonar testing (suspected), and other.
