It changes constantly as we're exposed to other people, social media, the news, traffic, the weather, good news, bad news, our own memories, etc. Crystals, on the other hand, have a super stable energy frequency that doesn't change.

Do crystals emit sound?

When the crystals are heated above a certain temperature (or cooled below it), their structure changes, scientists call this a phase transition. ... Although the position of the molecules only shifts very slightly, this happens extremely quickly.

Do crystals conduct energy?

Ordinarily, a crystal does not conduct electricity. But when the crystal strontium titanate is heated under the right conductions, it is altered so light will make it conductive.
