    Hiya guys, my lady wants me to soundproof a bedroom wall to stop any noises travelling from the bathroom into the adjoining bedroom, currently we have a wardrobe on that wall which we are moving, she thinks it may make any trumpet noises more pronounced, would soundproofing on that wall make any difference at all, i say not and i am telling her it would be a waste of time, whats your opinions? and if yes what would you use and how?

    living in fear of someone trumpeting in the bathroom :rolleyes:

    anyway, if stud partition wall then replace wall with a solid wall, or if this is not possible a sheet of thick rubber and then another sheet of plasterboard, a rubber sandwich between two pieces of plasterboard, is supposed to work really well. Easiest way to stop noise is with dense materials, so the heavier the wall the better, and remember a lot of noise can get through a very small hole.

    Acoustic rockwall batts in between the studs. Plasterboard the wall - 2 laters of 12.5mm or even better use acoustic plasterboard - although I wonder if fireboard could be just as good, its flipping heavy.

    Low frequency noise transmitts through material via vibration so dense materials are best for reduce them. High frequencies come through gaps.

    It really depends how much space you're willing to lose, there are some details on the knauf website in a PDF about all the different specs for walls, it covers up to walls between flats and even cinemas and other sensitive applications.
    The main principles are just isolating the wall surfaces, stopping the sound getting out of the room it originates and adding weight. A really cheap soundproofing is just to fill the wall with sand once you'd detailed it so it doesn't drop out

    Bear in mind that however well you insulate the offending wall, some sound will still bypass it via the adjoining walls, floor and ceiling.
    Sound is like water, it will find its way through anyway it can.
    It's also very subjective; you may think what you do solves the problem - she might not.
     
  10. If it's already built adding a layer of Soundbloc board would help ,but as others imply that wouldn't stop flanking sound transmission, although it should be ok for a partition between bathroom and bedroom :!:
