any idea how much stud wall sound proofing is?

Question

I`m putting a stud wall up (3.5mtrs x 3mtrs) how much does sound proof insulation cost , UK

Rough ideas welcome, thanks

Answer 1

depends how you do it - like most things in life there are cheap ways and expensive ways, easy ways and hard ways.

The double studded idea sounds good, so if you can be bothered to do that I would.

I've done it various ways in the past - rockwool works quite well, but to be honest no better than stuffing whatever you can in there - newspapers, packaging material, cardboard, old sheets. I even have a family size tent inside one of me walls!

Ask the experts though and they'll tell you the best sound insulator (apart from a vaccuum) is air. That's why my colleague who recently built a recording studio had two double-studded rockwooled walls, with a whole foot of nothing in between!

carpeting (or alternative) the exterior has an effect as well - mainly absorbing lower frequencies. Damps the echo in the room too.

If you've got money and want something easy, studiospares.com do various soundproofing tiles and flooring. These are quite limited I'm told, but have a good effectiveness to effort ratio!

Answer 2

Soundproofing A Stud Wall

Answer 3

To get a real reduction in sound transmssion, you need to build a double stud wall so the wall surfaces are not in contact with the same set of studs.

You use half the normal stud spacing but every other stud is set out just enough that the wall covering for the wall only touches and is fastened to the protruding studs. You do the same thing on the other side.

There is a picture on this website that shows this very well.

Answer 4

I have used the double ofset stud method many times in public spaces, particularly the WC's etc. But for sound proofing I refer to a previous answer I gave which is similar in a way to the Alexchappel one above in that the best insulation against sound transfer is VARYING DENSITIES. In his example, sheathing rockwool sheathing air sheathing rockwool sheathing. This is fine, but as a homegrown budget alternative I say use a cheap pinboard (Low density FibreBoard) then plaster and alternate them half a dozen times. Use old leftover bags of plaster. Supplement one of the plaster layers with some rockwwol perhaps, and for ultimate do this with offset stud to avoid transmission through stud. G'Luck

Answer 5

The thought has crossed my mind many times but with the advent of high power sub woofers, it’s impractical if not impossible. I personally feel that with the advent of the multi kilowatt music devices (insane), ghetto blasters, which have become a nuisance to home owners in that home owners are defenseless from it’s invasion. This sub base low frequency can penetrate almost anything. It takes the form of ground waves which by the way is employed by the Navy to communicate with submarines, so you can see the penetration capability is like a hot knife through butter. As long as selfish inconsiderate people are around, they will find ways to make others lives a living hell.

Answer 6

i cant give a cost but i can advise you to get proper sound insulation bats ..these are very dense and are heavy ..all so expensive but its worth it...look in yellow pages under insulation...if i was building it i would not build it in wood as wood transmits sound ..build it in metal studs ..and fill every gap with the insulation

Answer 7

It is all there for you, you have the measurements, take them to the Builders merchant, and you will get a price for the materials. If you cannot do the job yourself, perhaps they will put you in touch with someone who can.

Answer 8

just buy normal rockwool insulation, does the same job. can't help you with the price but its obviously cheaper though.
