We have some potters here - perhaps we can get one to throw a pot or two in the presence of readily identifiable sound?
But, I really can’t imagine unamplified voice being able to have any effect on the clay and the potter’s fingers as they work the clay. Nevermind damping, the stuff’s wet!
Lemur nailed it. Case closed.
Right up there with “record ambient sounds in a room and then listen for ghosts talking to you”.
