Maybe one could start with making and painting things, while blasting super loud sound at them, and do it with a robot so the only difference is the sound. Then check if the difference between sounds and no sound can be detected in any way right after the thing is done. If you get any results, just a reproducible blip, then try things you haven't made yourself in a controlled environment... but if you can't even get it there, it seems kind of pointless to mess around with really old things. That's my layman armchair perspective anyway, but from the armchair it makes sense :D
