Hi, I’m looking for some advice regarding some sound proofing options.
I recently moved into a detached house (so neighbours are not a problem) and had intentions to convert the garage into a dedicated home cinema room. However we are having second thoughts about that and now considering using one of the spare bedrooms. We have a young baby so will have to try keeping the noise down and I’m looking at options to improve the sound proofing. The baby’s room is located at the opposite corner of where the HC room would be (see attachment). Door to door is around 4-5m distance away. I have done a little research here but not sure what’s the best way to go. I’m not looking for 100% sound proof as that will be unachievable without spending crazy money but certainly if any good improvements made will be worthwhile. The room isn’t that big: measures 3.4m by 3.5m so I would prefer to lose as little space as possible for the sound proofing.
I was thinking of improving the walls highlighted in red and also the ceiling and the floor by doing the following:
· Main walls in red: These are plain stud walls which I believe have some insulation in them already (I found out recently when having to drill into the wall and it pulled out some insulation). I’m looking at removing the internal existing plasterboard and fitting a double skin of 15mm soundbloc plasterboard with a Green Glue interface. I’ll probably replace the insulation that’s there already with rockwool or acoustic mineral wool. Originally I was thinking of attaching this to the studs directly but read resilient bars should be fitted first to further improve dampening.
· Ceiling: I’m thinking of adding a 15mm single layer of soundbloc plasterboard to the existing ceiling with a Green Glue interface in between.
· Floor: I’ve read the best economical way is to lift the floor boards and fill the cavity with rockwool. Can you just lay this straight into the void? I’m worried if the ceiling below will take the weight as its probably just plasterboard. Are there any other materials I should install here i.e. other membranes or sound insulation inlays that will also improve things?
· Door: Install a fire rated internal door and seal up the edge.
Just wondering if anyone can give any thoughts as to the effectiveness of doing all this or anything thing else that I should consider?
