I'm not keen on hearing noise from a bedroom above (or they hearing me!), so got me wondering if anyone here has ideas on how best to acoustically insulated between floors of a two storey dwelling. I'm going to use sound batts between the ceiling joists for sure - that should help with airborne noise (TV's, talking). But I'm not sure about how to deal with impact/transmission noise (footsteps, kids jumping, etc). Would a layer of rubber-based matting be a cost-effective answer? Like this stuff maybe - http://www.soundblock.com.au/sound-proofing-products/floors ? Re: Soundproofing a second storey floor - rubber matting? 2Jul 23, 2014 9:39 pm Don't know about using rubber but we've spec'd Soundscreen insulation between our ground and 1st floor for the same reason. Re: Soundproofing a second storey floor - rubber matting? 3Jul 23, 2014 11:26 pm What are you having for flooring on the upper floor - timber ? Soundscreen batts are only part of the solution. You first have to isolate the impact noise from above as you already mention then you have to remove the ability of the sound to travel through the floor . The best way is batts then several layers of gyprock separated with green glue on resilient mounts ( isolation clips ) supporting furring channels. It'll come down to how much you want to spend vs how much you want to reduce the noise. This link here has lots of diagrams and how-to's. http://www.soundproofingcompany.com/sou ... a-ceiling/ Stewie Re: Soundproofing a second storey floor - rubber matting? 4Jul 24, 2014 8:06 am Thanks for the replies. We plan to use standard particle flooring upstairs - 19mm yellow tongue (or maybe 22mm red tongue). I'm after a fairly low cost solution as I'll be at the limit of my budget with this build. The reason I also think soundscreen/rock wool batts are not the whole solution is because of my experience of converting a timber stud garage at the side of my house into a sound-proof home theatre/music room. I double studded the walls, double plastered each with 16mm board, and stuffed the frames with rockwool. I also had a window, which was triple glazed. Totally over the top but totally soundproof. However, the ceiling was a different story. The garage had a slightly sloping flat-top galvanized iron roof. I put in stacks of rock-wool between the (hardwood) ceiling joists, and also double plastered the ceiling with 16mm board. The whole garage was sound-proof in terms of not being able to hear music from the outside, but if a little bird landed on the roof you could hear it walking around from inside the garage! Therefore my concern about impact/transmission noise.. Re: Soundproofing a second storey floor - rubber matting? 5Jul 24, 2014 8:16 am The impact noise from the sheet flooring upstairs certainly would be your biggest worry however the cost of isolating it wouldn't be cheap. You would have to use something like resilient mounts over the floor joists etc and that would cause other issues. This is the link for soundproofing floors... http://www.soundproofingcompany.com/sou ... ng-floors/ You'll note that all these solutions rely on the sheet flooring first then the soundproofing elements mostly above ( forget the soundscreen batts etc in the floor cavity below for a moment ). It is the impact noise you have to address and not having any floor coverings above makes it extremely hard to achieve that. I'd guess you are looking at carpet down the track ? You may just have to put up with it in the short term.
