I have recently been having issues with impact noise from the condo owner above. From what I can tell the best option is to install a decoupled ceiling system. However my case is a little different from what I have found due to what I believe may be weakening joists.
Basically the impact noise above is made worse by the fact that the floor is actually moving a bit. The reason I can tell is that my floor has the same issues. If you jump in the middle of the room, you can feel the floor flex and things around the room rattle. If I do this in a different room, it's rock solid. The bedroom happens to have the largest square footage of all the rooms.
In this case, I assume I would have to open up the ceiling to see if the joists are sagging or the subfloor had detached? Is there a fix from below that could be done in either case? I'm hesitant to go along the route of the decoupled ceiling if in fact the joists are moving. The neighbor upstairs is of no help so I can't approach this from the floor above.
Any help would be much appreciated!
