hey i live in a 2 story house and i live on the 1st floor and my uncle lives on the second floor. however when the people on the second floor walk around i hear the creaking and thumping on the 1st floor. is there any way to fix this? any way to dampen the sound? any way to make it more soundproof? if you have any real methods of solving this problem please post, thanks in advance!
The usual suspect would be wood rubbing against wood. It could be a subfloor rubbing against floor joist or hardwood flooring against a subfloor.
Most likely it is the latter, which would mean getting to those joists and bracing the heck out of them.
