Browse Forums Building A New House 1 Feb 22, 2016 7:23 pm Has anyone sound proofed any walls in their new build? We are considering doing the wall between the ensuite and bedroom 2, the bathroom between bed 2 and bed 3, the laundry next to the living room. Im just not sure it will make a huge difference. Does anyone have any advice on this? Also roughly how much extra did your builder charge you? Thanks Re: Sound Proofing 2Feb 22, 2016 8:07 pm We are soundproofing two walls in our build. We were quoted around $13 per m2 Re: Sound Proofing 3Feb 22, 2016 9:15 pm We are doing one wall between 2 bedrooms as currently my 12yo and 1yo share a common wall (which will be the same in the new house) and he wants there to be some soundproofing from all the noise the 1yo does and crying at night, early wake ups and playing in his room etc. Our cost is $170.40 on our paperwork. The wall is 2.9m wide and 2.77m tall. ~Shellby~ GJ Bridgewater 203 11/3/2016 - Site Work Started 29/9/2016 - Handover 142 Work Days 6 Work Days Over https://forum.homeone.com.au/viewtopic.php?f=31&t=80174 Re: Sound Proofing 4Feb 23, 2016 10:55 am There are varying levels of sound proofing you can use. Assuming framed plasterboard construction, the first level is to just use R2.5 HD fibreglass batts. These provide some sound isolation. A step up from that are denser insulation products, like rockwool. Then you can look at using thicker plasterboard (fire-rated/acoustic), then double layers of plasterboard. On top of that, you can get special glues for the plasterboard that can help absorb the sound. For theatre applications, where there's a lot of low-frequency noise, you can also double-stud the wall, with separate offset studs for each side of the wall to reduce the coupling. When specifying to a builder, you need to be clear about what you are getting for the money you are paying. I'd say that unless there are particular requirements, just putting the insulation in is a good measure, but where it's quite important, there's more that can be done. Re: Sound Proofing 6Feb 24, 2016 7:02 pm Glad you asked this question NicNak as on my mind also. Not fun when one person has to get up super early and despite trying to be quiet the inevitable bathroom noises make sleeping impossible. Definitely keen to soundproof the master bedroom in the next house. Thanks for the great info John, will be bookmarking for future reference! Re: Sound Proofing 7Feb 24, 2016 10:14 pm First option in isolating noise is to change the plasterboard, as mass is the easiest way to reduce noises. Various levels, cheapest would be to put 16mm Fire Rated Plasterboard on both sides of the wall. Then just your basic insulation inside. Most Studios all use Fire Rated Plasterboard, sometimes 3 or 4 layers on double studs. No need for more expensive special "sound" insulation or sheet. Not enough ?, just add more. If you have a really good builder, you might be able to get them to do the first option, and you could test on the spot to see if more is needed, once doors are on. Note - I said a very good, and nice, builder. There is another factor in your situation, where the noise of the water and pipes also comes into play. That gets more complicated as the pipes are likely partially touching the framing, noggins or studs. Those noises transfer into the plasterboard sheets. I don't know of an off the shelf cure, though neoprene or epdm insulators through the holes might help, but are likely not going to be cheap when plumbers, and variances come into play. Scientists have used random matrix theory to demonstrate theoretically that the neutrino mass hierarchy can be explained mathematically.
