    I am going to convert an upstairs room into a home cinema room soon, and am currently in the process of researching sound proofing.

    I am not concerned with sound escaping to other rooms within my house, and only want to do enough to reduce (and ideally eliminate) noise going to my neighbours.

    I have two walls which are shared with my neighbours, so my plan is to just sound proof these walls (using the stud wall-rockwool insulation-dbl p'board method).

    The room will have thick underlay and carpet - do I need to add any more soundproofing under the floorboards?

    In the loft space above the room, I was just planning on fitting some decent loft insualtion with T&G chipboard as flooring.
    The loft is only used as a store room.


    If anyone could advise on any other measures I could or should take to improve on my current plan, it would be greatly appreciated.

    Many thanks.

    Try doing a search in this forum for sound proofing and rockwool. You should get a few more threads to look at that should give you more ideas.

    Have a look Rockwool, http://www.rockwool.co.uk they provide a whole range of different insulation products that will help in your quest for a quite room.

    Another place to look is Custom Audio Designs, who are specialists in domestic soundproofing, http://www.domesticsoundproofing.co.uk

    Cheers.
    I have checked those sites out.
    I was just curious to wonder what effects better sound proofing of my floor and ceiling would have in cutting down noise "leak" to my neighbours.

    I was wondering if fiiling in betweeh the floor joists with insulation - maybe even Wickes 30mm heavy duty sound insulating slabs layered up, would help further prevent any sounds traveling under the floor and through to next door. Doing that before you put the new walls up could help - you'll probably only have to do it within a foot/18ins of the wall for it to be effective if it's going to be.

    It's just a thought, but it shouldn't cost much to do it, especialy as it might be harder to do after the new wall is up.

    Don't forget to silicon rubber all around the edges at the walls floor and ceiling of the new wall, especialy before putting the skirting back down.
