My floor may be marginally better than some - it's an engineered hardwood floor (basically plywood planks) laid on a few mm of foam, over a particle board floor on joists (I used to have carpet). I also have a big rug in the middle of the room and quite a...

Re: Back from Dallas and depressed ...
It's the solid concrete. There's nothing to damp standing waves, so room modes are maximized. Framed drywall construction actually helps damp room modes because the drywall flexes and absorbs some of the bass. That's a good thing where room modes are c...
