It makes sound, otherwise acoustic energy for free?

When it pushes, and releases, the material pushes back.

If it is microphonic, perhaps it has defective internal
terminations, or are you saying that they all sing?

I still don't see how it is a loss. The dielectric constant
probably includes such physical flexures whereas a polymer type
dielectric only flexes internally at the lattice level. Still, it has
hysteresis as well.

In this case, the hysteresis sings audibly. I don't see how it is a
loss though. It is more like a response to stimulus, but I don't see
that it would have much consumption, if any. It very well could be
just that though.


If a light bulb gives off light, is there no energy used in creating that
light?

I am just saying that it the result of the hysteresis, and is
therefore included with, and accounted for by the parameters already
characterized by us for that given medium.
