    Hi,

    In my quest to soundproof my garage conversion I've come across THESE . Anyone here used them? are they worth the effort?

    I'm pretty sure I've seen this stuff used in a basement of a house that had a concrete ceiling.

    Dunno if it's worthwhile though, sorry.

    Thanks, I've spoken to a builder who reckons they are a waste of time, but I'd still like to hear from anyone who has used them.

    resiliant bars can be good for soundproofing a room, but can also be terrible for accoustics - they can act as bass traps for the room, and no matter how many subs you put in there, you may never be able to get a good bass response.

    A 4x2" wall built an inch in front of the wall you wish to soundproof, filled with rockwool, and finished with 2 layers of plasterboard is a good method that seems to work. The walls are stiff and won't act as traps, but the mass of the plaster board helps prevent some of the bass travelling into the adjacent room.

    With that method, any acoustics can be dealt with with treatments, but if the resiliant bars are used, and you do have bass problems, the only thing to do is rip it all down and remove them.

    Thanks for the advice, I've done away with that idea now, I'm just building stud frame with 2 15mm sheets of Soundbloc plasterboard, and filling it with rockwool.

    I thoght so, resilient bars and the like look good on paper, but it's expensive, and a whole load of hassle.

    And the last thing I want to do is have no bass! especialy after I've gone to the troube of fitting 2 12" subs in my floor!

    You can at least tune the bass with that set-up. You couldn't have done anything if the bars had dulled it all for you.

    Sounds like it's going to be a stonking room - got any pics for us all to see the before, during and after?

    Gary.

    I keep meaning to take some picture, but theres not much to look at yet, I've just finnished the floor - which was fun, It sound quite simple to build a couple of MDF speaker enclosures into a timber floor, but getting all level is not that straight forward.

    At the moment I'm having more fun with a fire door...
