Sonochemical Cavitation.

Could someone give me the simple Straight Dope on this. What the heck is it. What effect does it have. What dangers, if any, does it pose in the brains of humans. I was looking up some info and found a short sentence on dolphins capable of causing cavitation with their ecolocation. And that there have been noticed effects in people after have contact with dolphins.
That was all it said!! How are you going to leave someone hanging like that. What are the effects???
I have a vested interest in this since I work with dolphins weekly! Are they killing me!? Am I going to be retarded (ok, more retarded) soon??

It’s basically talking about the effects of powerful utrasound impulses. Ultrasound can cause hazardous effects if powerful enough, mainly through heat generation and possibly cell disruption. Whether a dolphins echo location and ultrasonic communication output is powerful enough to cause these effects is unknown to me.

Here’s a page about it

EEK! That is well within the capabilities of a dolphin! Holy Crap, they’re killing my molecules!

Thank goodness I have so many, right?

Wait! That sounds like a good thing.
