Actually, you're wrong

"Excitation of the atoms are generally regarded as being part of the piezo effect."

As I just got through saying the other day, the piezo effect is regarded to involve the *deformation* of the crystal, the old squeeze/voltage thing, remember? The voltage is proportional to the squeeze/deformation, remember? Hel-looooo!!

"The laws of thermodynamics impose a conservation of energy. You can transform the energy but you can not eliminate them.

Well, DUH! - is there an echo in here? I just got finished saying that.

"I believe we are using the crystals to take the absorbed energy and convert them into heat through motion."

Geez, Luis, I just got finished saying that, too..

Seems odd you're commenting on things you haven't tried, I thought that was against your principles or something. Anyhow, crystals are actually outstanding for dissipation of mechanical and acoustic energy - out in the room - due to their physical characteristics. That's why SteinMusic, Acoustic Revive and yours truly are using them for controlling room acoustics, among other things. You're simply making (Geez, another) Strawman argument by comparing crystals to diffusers, mass dampeners, room dampers and such. You DO know what a Strawman Argument is by now, don't you??!!!!

"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."

Pity Verizon Hall doesn't use crystals. But not too surprizing, even most audiophiles don't use crystals. These things take time to work their way into the Acoustical Society of America and AES old school types. LOL

Same goes for your statement, "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." Yup, you guessed it folks, another Strawman Argument!
