Soundproofing Site

Just thought I'd add this to the newsgroup on account of the regular soundproofing queries that come up:-

't looked into it deeply but it seems they do acoustic solutions of the extra-stud-wall-of-plasterboard-to-cut-down-the-noise-from-next-door variety.

The points I noticed were that there is such a thing as 'acoustic mineralboard' which is useful to know, and also that they have sandwiched a sheet of rubber between two sheets of acoustic mineralboard to give added attenuation. This is basically the best way to stop noise when there is limited amount of space available, since the limited mass of the mineral board stops noise by reflection, and the rubber and the special properties of the mineralboard absorb sound that makes it through.

There are still practical difficulties in mounting the boards so that sound 'leakage' paths do not develop, so negating some of the performance of the composite boards.

I didn't have a look at the whole site but it wasn't totally convincing - more aimed at the DIY'er who wanted a quick fix rather than serious sound proofing. If you have to use stud walls then proper soundproofing involves multiple layers of plasterboard with a flexible layer in there somewhere. I would be interested to see an attenuation against frequency plot for their treatments.

Cheers.
