Currently there is one layer of 5/8's drywall with bat insulation with 2 x 6 wood studs, 9' autistic tile ceilings with fire walls going 5 feet up past ceiling to roof. You just can bare here voices on the other side. need to eliminate. should I use regular sheetrock or Quiterock? I can only go to the 9' ceiling. I know about sound flanking, but I will have to add bat insulation to ceiling currently have 6-8". I have been researching, and finding out this is a science in it self. please help.

Not sure a 2x6 wood wall is considered a firewall...


Quiterock is not popular on this site, it's all about adding mass and the best for that is more 5/8" drywall. Why can you only go up to the acoustic tile ceiling?

Let me give you an analogy. I have this submarine that came without a hatch. It does have a screen door, Would it help if I covered it with a water proof tarp?


It might be helpful if you read the articles at soundproofingcompany.com


If you want serious soundproofing you need to add Isolated, Damped, Mass to the entire partition wall between units.

thanks for all the advice, I am  going to do in steps, first the 9' below ceiling tile and if I still have a problem, slide 5 foot pieces up above ceiling tile in between duct work I will just have to tape and mud where I can get to. What part of Northern VA? I Grew up in Leesburg. Been here in Myrtle Beach since 84.
