Treating the ceiling and floor, who else has had great results?


Two areas of the room often neglected by audiophiles IMHO is the ceiling and floor.  We focus so much on first reflections we forget about overall energy left in a room after the speaker has stopped.

I've had excellent luck with treating the ceiling, especially for home theater applications, and this was before Atmos.  The area behind the speakers near the floor often hides noise and distortion which we didn't know we were hearing.  Throw a blanket over there and listen for yourself.

Who else has gone through the trouble of treating their ceiling?

Ceiling: completely covered with 14” of rock wool, which is covered with fire-resistant burlap

Floor: mostly covered with Moroccan and jute rugs.

Walls: see ceiling, but 5”.

I would say that 75% of the room surface is deadened. The room is about 25-30 db. It is semi-anechoic.

I was able to include a dedicated listening room when I designed  and built my home. I installed a diffuser at the first reflection on the ceiling as well as the walls. The walls also have absorption at the second reflection. The floor is carpeted and has one joist space at the first reflection that is grated and filled with fiberglass insulation. The music sounds amazing.

Large room with high ceilings a wood floor here. I fitted a 10’x14’ area rug with 2 layers of carpet padding underneath between the speakers and my listening position. Before and after REW waterfall plots show a marked reduction in early reflections from the floor beginning around 1k or so on up.

Thanks for that.  We are a little off-topic as I didn't want to talk about all floor treatments, but yes, this is worth doing.   If you are measuring room resonance times the floor treatment won't show up, but it will in waterfall testings.   So, yes, Darko is right, the floor is not the end-all, be-all for room treatments but we also can't ignore it.
