I hope that the mods won’t take me down, but I have two great videos by a guy that does some great DIY stuff:
Basically, thermoacoustics is that air expands and contracts as it is heated and cooled, which can create air flow that in turn makes things resonate. A thermoacoustic refrigerator compresses air at a certain point in a tube. When air is compressed, it warms up, and this heat is then drawn away from it. When it expands again, it has less energy than before and is therefore cooler.
