I am planning on building a studio/home theater in my basement. I will use it for movies and eventually drums (yes of course, drums) but I am mainly interested in home theater right know. I have seen 8 billion ideas on how to do this, but was wondering if anyone has done this. I have neighbors on both sides of me seperated by concrete walls. I was planning on using two layers of drywall 1/2 AND 5/8 With resilient channels, acoutical batts and a prayer. I was going to place the walls about 9 inches away from the concrete and put 4x8 2 in thick foam board on the outer sides. Same with the ceiling. ANY ADVICE WOULD BE GREATLY APPRECIATED. Thanks
I made a music room in my basement, and used the 'double wall' method. This turned out to be quite efficient at filtering high frequencies, but not so well for the bass. If you share a common concrete floor with your neighbors you are going to find the bass transfers through the floor and you might get some complaints.
A few months back I was talking to a guy who worked at a lab doing independent testing on acoustical isolation products. He refered to Green Glue as a "wonder material". They did a lot of testing on GG and different Iso Clips. He said that both of those products did a great job but when they combined forces they performed better than anything he has ever seen. If you were going to build new walls anyway you could build them just a few inches from the cement wall and stuff the cavity with fiberglass. Add the hat channel and iso clips, then 5/8" drywall. Tape the seams and add the 1/2" with GG. Thats about the best you can do that I've ever heard of. You will just need to think about the ceiling. The same can be done for that too.
I did a very smart thing; I put all my equipment in the basement and crudley put it all together and cranked it. I then went next door to the neighbors and I could not hear very much at all. There was a little to much bass and it was heard mostly upstairs. They do not have a finsihed basement either. I may just take the easy route and go form there. ANY IDEAS OR WARNINGS?
You should still finish it though. It will improve isolation even further and improve the rooms acoustics. A typical wall will act as a resonant absorber around the 60Hz range. Not only will it improve the rooms acoustics it will increase resale by having a finished basement.
Yes, due to unforseen delays, I only have the stud walls up. What ideas/solutions do you have? I am no longer using RC-1 instead plan on making a new celing (room within a room.
