cold sound.

What property of a material gives it its resonant frequency?
If sound(wave) can excite the particles in a said material such that it makes the material rise in tempurature, what could be done with the same, or multiple waves to make the material drop in temp? or absorb heat?

would you even need to lower the temp?

I was looking at some technology that uses sound waves as the base component in a refrigerator. This made me currious.
maybe it works around the principle of make the temp of the material have a large enough difference between it and the room temp, that it can create a gas exchange (like in a sterling engine) and use the properties of the gas to act as the cooling agent?
