Sonoluminescence

I was looking at the different mechanisms generally used to multiple frequencies, and hit upon an old friend, sonoluminiscence.
Basically, this is a process where, by setting up acoustic standing waves in water at ultrasonic freqencies, at resonance, one can see that the bubbles of air in the water implode with a bluish-white light flash. So far conventional physics has no explanation of this process.
There are two factors that are there worth noticing. One is that the effect is happening at an interface: the liquid-vapor interface of the bubble with the water. Secondly, at resonance, this creates a light flash which is roughly 600 THz in frequency, while the starting frequency was nothing but 25 kHz (based on the experiments done). This gives us an order of magnitude of nearly 24 x 109 in the change of frequency. This is roughly the range of the speed of light!
I am not sure what I am getting at here, but apparently by doing it at the interface, we are gaining the reduction of a dimension of motion. In other words, by setting up resonant systems, one can get the same effect as that of cooling stuff down to very low temperatures. Another clue is the fact that by reducing the temperature of the water, the flashes grew brighter, which means we are augmenting the effect.
