Eldritch, since you seem to know what your talking about, what would it take to get enough sound isolation in a room that you could have a lawnmower going outside one wall and not really hear it?
I've got a garage I'm looking at converting into studio/bedroom space, but its built out of single brick and is right alongside my neighbours pool, so I need some powerful sound isolation
I'm thinking about lining the walls then putting in a layer of rockwool, then leaving a gap and then putting a green glue layer on the outside... But I'm not sure if it'll work... |
A room within a room construction is probably needed. But first, what exactly is the outer wall made of, just bricks? Because you don't want to create a 3-leaf consruction. That will only cause problems. This means you don't want to have two separate air gaps.
I made this crappy paint illustration. The yellow parts are wooden framing filled with insulation. The white is plasterboard. As you can see there is nothing covering the insulation on the outside of the inner wall, that's how it should be.
You can reinforce the brick wall with plasterboard if you want, it will probably help with getting it airtight. But it's important that you don't create another air gap.
If you make both of the walls airtight you should get very good sound isolation. But ventilation is very important in air tight spaces. You would need to build a ventilation system with duct silencers.
