thanks for all your replies there all good!
I do try and do as much as possible in my headphones (HD25) and usually end up doing the mix down in them but would really like to do it through monitors.
I have some old thick padded duvets spare, would taking them to the ceiling/wall help prevent the sound leaking out? |
Did you even read my reply? You need MASS and air tightness to stop sound leakage. What you're describing is acoustic treatment (a poor way of doing it as well) and doesn't do anything for sound isolation.
Read my earlier reply again and if you have any questions I'd be glad to help. |

Ye i did read it, thanks, i was just asking that question to see if i could make any use of the old duvets towards trying to bring the sound leakage down. |

Do duvets have a high mass? NO
Are they air tight? NO
You need to make the walls (+ceilng and floor) heavy and airtight. |

Also keep in mind that any weak points need to dealt with. I'm talking doors, windows and ventilation.
For doors it could help simply to replace it with a massive MDF or wooden door. And add weatherstripping to the cracks to make it as airtight as possible.
For windows you can add an additional thick glass pane, but the best option would be to just cover it up.
Ventilation ducts will probably not be a big problem, and would only need to be adressed if you're going for high sound isolation, i.e. a room within a room design. |

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:nervous:
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. |

Yes thats right its just a single layer of bricks... So from your diagram its not worth using green glue at all?
Also, how would I go about making it airtight? Its an old building, the bricks are probably a bit the worse for wear and its got at least one nasty crack on one side (the side I actually need insulated:( ) |

You can use greenglue between the two layers of sheetrock of the inner wall. I don't know about the bricks. Maybe you could use some kind of cement on the bricks to seal the cracks? |

| Yeah, probably cement will be the way to go I'd guess. I'll just have to worry about doors and windows now... Do you know whether theres any good options for doors and windows you can open but that also isolate sound well? I'm trying to work out the best way to get a big pair of glass doors onto this courtyard bit while also keeping it well isolated... |

Windows and sound isolation don't really go hand in hand unfortunately. There are solutions but they are expensive and hard, if not impossible to do by yourself. You need very thick glass panes, that's for sure.
Doors are easy. Any thick, massive wooden door will do. Add woodenstrips to the existing doorframe with rubber weatherstrips inbetween the wood and the door, like in this image.

No problem, let me know if you have any more questions. I built a vocal booth with great results so I have some practical knowledge on how to solve certain problems etc.
I also recommend you check out this forum.
