In our dining room we've had a plywood base screwed onto bare floorboards, with a solum/floorspace underneath, and then cork tiles glued onto the plywood. All good so far, but it's boomy loud - it's almost as if the floor is acting as the skin of a drum, and the noise is either booming in the room itself or the floorspace underneath.
Is this normal? Anything we can do? Anything that the installer may have got wrong, e.g. not screwed the plywood down enough in the middle? The plywood sheets must have been 2m x 1m, fairly big. And I've just noticed that the edge of one of the plywood sheets actually moves up and down slightly when you walk on it - would this be the problem? Other parts of the room are noticeably quieter.
They're coming back to finish other work so would like to be prepared if there's anything I should ask them to fix.
