Hello AVS Friends...my wife and I just went through the process of new construction and I was fortunate to have a furnished basement which will be used as a theater. Wiring for speakers was installed but unfortunately we didn't have a chance to influence sheet-rock/insulation (long story). So the room is standard sheet-rock over blown-in fiberglass insulation...the ceiling has two "beams" that have HVAC ducts underneath and the rest is insulation. I added two pics to this post showing the before and after.
Problem is that this room is directly under the kitchen/family room. So not only does the boss say that she can hear EVERYTHING coming through the floor when I'm watching a movie, conversely I can hear people walking around and even heard the "sweep, sweep" sound of the boss sweeping the floor the other night. So...there is basically zero noise dampening either way and based on some initial research, I'd say the fiberglass insulation is likely transmitting the sound rather than dampening it!
First of all, I'm under NO illusions that I'll completely sound proof the room. That's not the intention at all...I'm just trying to add SOME sound separation. Even a 50% improvement would be huge. And I think it's just the ceiling. The walls are virtually all outside walls or walls to the crawlspace.
So, to avoid a pit in my stomach I'm trying to avoid the "what I should have done" and focus on what I can do moving forward...
Obviously there is a full meal deal solution of ripping out the ceiling sheet-rock/insulation, adding acoustic dampening material of some sort (not an expert here), re-sheet rocking and re-painting. I'm posting here in an attempt to find a solution that is not quite that extreme. I spoke with my builder who spoke with his "insulation guy" (neither are claiming to be experts) and they are saying I should explore screwing some "sound board" directly to the existing drywall then adding a small false drop ceiling (dry-walled) over that with a bit of space between. If something like this would work, it sounds like a cheaper/easier solution than ripping everything down, but I wanted to get some feedback from the experts here. Thoughts on solutions? Thoughts on materials to use?
Appreciate any feedback!
