I was wondering: if it starves the fuel of oxygen, it stops the fuel from burning, even if it's still hot, yes? So if it could scale from frying-pan-level to house-level, at the very least, couldn't it be used to suppress the fire, the smoke production, and the further weakening of the structure, to allow a squad to search and rescue more safely? Then when you turn off the sound, maybe the material has cooled below the reignition point, but even if it hasn't, at that point you can fight the fire traditionally.
