Wooden hatch door, it's about 1.5" thick plywood but quite loud below when people walk over it, despite having carpet on top.
It closes against a metal jam so I was thinking of putting some dense foam on the jam so the door would give a little. It could however be a bit weird for those walking over it however (usually paying guests staying for a few days max).
I was thinking the egg-crate foam is more designed to stop sound hitting the crate side, so whereas that would be good so they don't get noise from us, the main problem is the drumming of this door.
Any easy solution other than replacing the door with something more rigid?
