I'm converting my third floor / attic into a studio. In the process of doing so, I'm trying as best as I can to provide some sound isolation.
We're talking about a 100+ year old house here - so it's not going to be an easy task. With that in mind, I'm not looking to block the sound entirely, just the best I can without breaking the bank.
Right now I'm working on the floor - the old one has been ripped out, and I've straightened the wooden beams. What I have in mind is to fill the space between with isolation (+- 20cm), and actually place three layers of new floor:
- acoustix panterre (a Belgian product meant for sound isolation)
- OSB boards
- wooden floor as finish
My initial idea was to place the first two layers floating, and glue the wooden floor to the OSB.
It seems though, that the OSB should be fixed to the beams with screws. I recall reading this would be bad for sound isolation, but good structurally.
Sound isolation is rather confusing at times - is adding a few screws immediately having a big impact on the global sound transmission, or is the effect limited?
