The short, not-very-informative answer is "sonoluminescence". The long, not-very-informative answer is "no one is very sure what's going on". Several colleagues have done detailed studies of sonoluminescence in near-zero-g [Dzikowicz], have written review articles as to its mechanisms [Matula], and so forth. Hopefully, that gives one a narrow avenue of inquiry to follow.

A student send me this video clip. Scroll down to "Play Video" It's of a
shrimp that produces a sound so loud it produces light -- and a water
temperature of several thousand degrees! Amazing! How is this possible?
