Sound proofing playrooms (15)

A well fitting ballgag is a much cheaper alternative...

Normal fibreglass insulation is a poor sound insulator, however you can get sound proofing quilt from the same manufacturers. It is about one inch thick and comes on a roll about the same size as normal heat insulation. Most builders merchants will order it for you. The hardest part is stopping noise transmission along solid items such as joists so the best way is to stop the sound reaching them in the first place. Windows are best insulated with secondary double glazing with about a four inch gap.

I note you have had several sensible replies already. Since you rent, however, I suspect you cannot make any serious alterations to your house. And, of course, it would be a great shame to interfere with original Edwardian features-in particular any alterations to a party wall would probably destroy your cornicing. Sound is primarily transmitted by air, in the form of leaks or draughts. Secondary glazing, a thick carpet to cover gaps between the floor boards, and blocking the chimney (take advice on this), may make quite a difference. Sound is next transmitted through solid objects, and reduced by mass or weight. That is why recording studios have lead in the walls. Thermal insulation, such as glass-fibre, is of limited use because it so light. Wardrobes full of clothes in your alcoves would be more effective. In short, it is a difficult business to reduce sound transmission. You might try playing the radio or something as loud as you think your "parties" might be, and asking your neighbours if you may go next door to hear how much can be detected. You may be pleasantly susprised! Or invite them round to join you? Hope this is of some use. Cheers

Hi, I've read through the rest of the posts, and there's one thing I've read about thats not been mentioned yet (at least, i didn't see it). If you've got a way of hanging a duvet over the wall, this should help absorb the sound (more so than egg boxes!). I've heard of this being used to good effect in home studios. The only problem I can see would be rigging something up to hang it from. hope this helps... Cheers!
