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?

that is major. why can't I 90 degree some Styrofoam at ceiling and wall to stop flanking.

Styrofoam is good for beer coolers, won't do squat for the sound. If might be easier to beef up the other side of the wall.

So you think the flanking problem is a real issue. can I add more sound insulation near wall.

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.
