Soundproofing

Most materials sold by places like ASC and GIK (my fave) won't help you.


You need mass. The best Ideas I've read about are to use 2 layers of drywall with resilient channel in between. I encourage you to google for more specific solutions.


Here is one example, maybe it will help you on your journey

PS -

ASC and GIK are great for treating how the INSIDE of your listening room sounds, and they may also have sound proofing materials.
What I meant to say is that the two types of products and practices are different.

I have done the two drywall layers with a "a channel" between them. It works very well. However, bass waves are so long, it's pretty hard to keep them from penetrating and leaking into other rooms.

Erik, actually ASC do offer a complete soundproofing method and materials but it is complex and expensive to implement if you pay someone else to do the work, not sure the OPs building competence but if you are prepared to compeletely rebuild the roof this will work. Likely the limitation would them be the stairs and door down which will be hell to proof effectively (the door was ultimately the limiting factor in my room, no matter what heroics we went too bass leaks through it despite double doors and seals)
