For example, glass and metal dishes create so much noise that the gods would hear it, but plastic masks a lot of noise when I put dishes away.

Typically it’s a matter of the material’s elasticity. The more elastic it is (that is, the more it tends to bounce back to its original state when deformed, like metals and glass which dont’ like to be deformed) they’ll create more noise (which is just vibrations in the air) as a result of being struck.
Soft plastics, like tupperware, typically have a more muffled sound on impact than say a crystal wine glass, or a metal bowl.
Some materials are so elastic they’ll generate resonating sound just by rubbing them. Search youtube for “aluminum rod sings” for an example of this.
