G'day everyone,

I made that last post a few hours too early. I have now had a reply from CSR Bradford. They have rockwool slab available in 60, 80 & 100 kg/m3 densities and 25mm & 50mm thicknesses, but their sizings are 1500x1200 which may be more useful in some instances. They tell me that theirs is the only Australian-made rockwool. The price per sq.m area is comparable to the other companies 1200x600 slab. :)

Does anyone know where to get acoustic doors seals and neoprene strip? I tried James Dolman but they do not do them. I also tried Custom Audio Design and they quoted £144 to fit out one door and frame. This seems a bit steep tp me but don't really have anything to compare.

I live in Somerset but anywhere in the country would be good.

Cheers, Bluey

Just going back to Martin Walker's post on open & closed foam.
I'm trying to build some acoustic treatment panels (to stop high & mid freq reflection) and bass traps and have got my hands on around 2 cubic metres of packing foam which I'm assuming is 'open'. Each panel is around 50cm square and about 4cm thick - is this ideal or should I be looking at branded stuff like auralex?

Also - is the expanding foam gap filler you get in cans any good for acoustic treatment? Been doing some DIY with it and it sprang to mind for filling bass traps.

No material is ideal when you have no real idea of its acoustic properties ;)

However, try temporarily piling it all up in a corner of your room to see if it makes an audible difference - if it does then it's worth pursuing the idea.

I very much doubt that expanding foam filler will be of use acoustically, since it's generally used as a gap filler and to solve draught problems - this means it's definitely not open cell, and so it won't provide absorption.

Sorry!

One trick I've used a lot is to buy 'painters dust sheets' from DIY superstores: they're very big (10' square at least) and usually made of raw cotton. I used to find linen ones but haven't seen them for a while. The material is acoustically transparent and ideal for stretching over frames filled with rockwool etc. My current studio has some moveable absorbing/reflecting panels made from thick plywood; one side plain, the other covered with fibreglass and then these sheets stretched over and stapled. They do sometimes have seams though, where strips have been joined, but it's a lot easier than using a sewing machine.

Hi

First time here, bumping this thread, and strictly speaking this isn't music related but I would really appreciate some good advice.

I have a first floor flat and under my bedroom is someone's living room, through which I can hear all their conversations and TV noise. The bedroom is about 17m2, with a timber floor. There is already some kind of acoustic mineral wool in between the joists but frankly it 'aint working. I've considered a couple of options: 1) Seal the floorboard gaps with acoustic mastic, put down an acoustic membrane, then something like Quiet Floor, then the carpet. 2) Overboard the floor with some plywood, put some Green Glue on, then another layer of ply, then the carpet.

I don't think I can put down plasterboard or a floating floor as I don't think the floor/ceiling below will support it. Also, my budget is not unlimited, which is why I'm shying away from Quiet Floor and that kind of stuff. Anyone have any suggestions? I'm based in North Yorks and I'd also like to know of any good suppliers round here.

hi dear people I am in a panic rush so please excuse me if i might be asking in the right place but i hope i am ...

i am about to do up my studio now the walls of my room are made of 9 inch lime stone but still need to break the sound from next room and the dear neighbor so anyway i am using 30 mm rockwool with 2.5 inch wooden studs now i had the idea of fixing this 2cms rubber foam in between the stud and the wall so that sound absorbed by the plaster board on to the stud will not leek to the wall i already fixed one stud and it looks fine of coarse i have tighten it a bit so the size of the rubber foam and squashed a bit if you know what i mean .. now the BIG question is what guarantee do i have of how long the rubber foam lasts i am worried that it will disintegrate and of coarse the studs fixed to the wall will loosen up and the room starts to fall apart lol :headbang: i hope i explained my self clearly and i really do hope that i can get some help the weekend is coming up and i really wish to get on with the work :angel:

thanks and i wish you all a great weekend
greetings from Malta

I'm about to build some absorption panels similar to ones built by Paul W in http://www.soundonsound.com/SOS/jul06/a ... s_0706.htm
Is there any functional difference between Auralex wedgies and Sonomatt acoustic panels (both 2" thick) for facing the rocksilk panels with?

Another question: should I treat the rocksilk face at the back with something to seal it, and if so, with what? I read that PVA glue diluted with water about 20 times and sprayed on works well, but would welcome suggestions/comments.

Picking up on the open / closed foam thing, and the the suggestion of sealing rockwool/rock silk, either by wrapping in polyester batting, or spraying with diluted PVA - won't this then decrease absorption by reflecting sound, and thus defeat the whole object?

Apprently not. I have not used the PVA technique but I know there are quite a few fans of it around here. The PVA is watered down a lot, and the idea is to give a light mist rather than saturate the Rockwool. Remember that Rockwool is bonded with some kind of glue solution during manufacturing anyhow - that's what makes it semi-rigid and stops it from collapsing. The additional PVA solution just gives a bit more help in preventing the fibres from escaping into the room.

With regard cloth, so long as it is breathable it should be fine - hold it up to your mouth and see if you can breathe (if you can't - don't hold it there for too long!).

I think if either of these do reflect HFs it would only be right at the top of the spectrum where most of us have buggered our hearing up enough not to notice anyhow!

I'm no expert on acoustics though, so if I have said anything wrong than plaese someone correct me.

Cheers

Hi

I'm about to rent a room for my project studio which I will need to soundproof. My issue is I would like to be able to install in such a way that I can bring any material with me when I move on. I've come across this material'sound stopper panels' in studiospares which they claim can simply be fixed to the wall (screwed?):

http://studiospares.com/pd_465000_SOUND%20STOPPER%20ACOUSTIC%20PANEL%202m%20x%2012m%20x%2014mm.htm

does anyone have experience with these, and indeed will I be better off using the traditional methods and not wasting my money?

many thanks!

Simon

Just so people know, Rocksilk can be bought in densities from 33-200kg/m3. Here's a link to a Rocksilk data sheet from a company based in the UK:

Hi guys.

Does anyone know of any Rockwool or Rocksil sellers in the Hampshire area? I'm looking for 1000x600x100 slabs of rwa45 or rs45. I spent an age looking and asking around diy stores with no luck. Local Travis Perkins branches told me they wouldn't be stocking it anymore and i'd have to go to the Oxford branch!!!

Any help would be greatly appreciated.

Cheers,

Kiz.
