Somehow, I had no idea sound, vibration, was a quantum particle. A phonon... But now I know... So this means all the quantum weirdness applies to vibration and sound.. So this must mean a observer changes things by observing

Physicists split bits of sound using quantum mechanics
New experiments put phonons — the tiniest bits of sound — into quantum mechanical superpositions and show they are as weird as other quantum entities.
