of the atoms are generally regarded as being part of the piezo effect, and in diagmagnetic material, which pretty much all materials are, the E or H fields passing through the material generates a movement of the electron field related to the direction of the field applied. This of course creates a slight magnetic field because the electrons tend to move towards one side of their orbit ( at least the outermost electron shell). It is this transformation of the energy field which makes the use of crystals important in my thinking.
The laws of thermodynamics impose a conservation of energy. You can transform the energy but you can not eliminate them. I believe we are using the crystals to take the absorbed energy and convert them into heat through motion.
By your thinking, actually all materials, irregardless of their composition, has a certain mass damping effect. Room tunes uses fiberglass fill on their corner tunes, Enacom uses a plastic sticker: Harmonix uses a a little chicklet sized piece of constrained layer damping. All these devices transform the acoustical energy in a room into another form.
You don't need a crystal, and certainly a crystal may not be the optimum device for room damping.
Check out the new Verizon Hall in Philadelphia: they make extensive use of woods to break up reflections and to dampen sound. You don't see them using crystals in their acoustic design. No musical instrument I know of uses crystals to generate their sound, which says a lot about the use of crystals to control acoustic modulation.
Of course YMMV
