Sorry if this is repeating a common thread. We have recently purchased a new build detached house and noticing airborn noise between the upstairs and downstairs rooms. We also have a lot of joist movement noise, but the builders are coming back in a few weeks to remedy this by installing noggings. The ceiling / floor joists are engineered timber joists with chipboard above and 15mm regular plasterboard below. Nothing inbetween, just air. As they are going to be ripping up the upstairs floors, we have an opportunity to install some acoustic insulation. I am thinking just some acoustic slabs at 100mm and 60kg/m^3 (RS60 or RW3). My question is does anyone have any experience on doing this and how much effect it actually will make. I am nervous we do this at quite a bit of cost and lots of trouble and in the end the result is minimal. Is it worth the effort? I am surprised that the part E regs do not cover detached builds at all....surely they still require airborn noise regs. Thanks.

Our house design has an internal soil stack. So we need to think about noise. Have a look at this diagram. The brilliant thing about our design is that the wetroom is built onto the front wall of the house - so (below the level of the flat roof shown) there are insulated blocks inside the heated envelope. That means we can cut out the insulation and use the space created for other things - like hide a soil stack. And deaden the noise. But I only get one stab at this little problem. I need to get it right. So I'd like to fit acoustic piping (like this) or (maybe this) additionally encapsulate the acoustic pipe in sound-deadened (proofed is impossible I think) trunking. maybe double the amount of plasterboard on the ceiling under the upstairs bathroom meet and exceed the proofing levels required in Part E Have you had to deal with a similar problem? How did you work it out? Is the general approach outlined above sensible? Do you have any comments. I'm feeling a bit 'exposed' on this one.....

As we progress with the 1st fix, spent last week running almost 3km of a variety of cables around the house and through the posi-joists. Next week will be tackling the mvhr ducting, which has got me pondering on acoustic insulation between the ground and first floor. At the moment planning on 100mm of earth wool slab, then plasterboard nailed to the posi-joists beneath. The joys of forums and the internet has now got me looking at resilient bars between the posijoists and plasterboard and sealing everything up with acoustic caulk (green goo). However wondering if it is worth it, surely the mvhr ducting will act as a giant diggerydo and the plenums breaking into every ceiling / room? Or is this even more reason to do it, as a mitigation exercise? Also how should the ducting be installed to minimise noise, laid on posijoist bottom section, dangled down on cable ties in void or brackets screwed in?
