i'm skint, but am wanting to delve into acoustic treatment before i spend anything else on anything else. i was thinking about buying cheap duvets & pillows to attach to the walls and ceilings, would this work or am i just talking some major league bullshit here. I don't care about being too warm, i'll drink lots of water if it gets hot & wear an ice helmet.
 
Just save your money until you can buy some rigid fiberglass (or similar)...
Something between 40/50 kg/m3 should work...

There´s tons of info on the forum... Prepare a cup of coffee and spend a couple of hours reading! :)

They will work for mid-high frequency stuff, but will leave your bass to boom away. Get yourself to a builders merchant(travis perkins, rowan timber, etc) and get yourself some rocksilk RS45. I got mine for £20 for 10 2"x4'X2' panels. It is similar to rigid fiberglass(although quite nasty to work with) and will greatly improve your room if placed correctly. Just frame it and wrap it, like recommended in this forum. A doubled up, 4", trap in each of the four corners, halved 1s(2'x2') in the side reflection points, and the remaining on the ceiling reflection point will help loads. Then you can have a duvet on the back wall if you wish.

All good advice. Look here for where to put everything: http://www.gikacoustics.com/room_setup.php

There's also lots of other use information under the "education" tab.

Good Luck!

hey thanks for the info, i'm going to check nearby stores to see what i have to play with. Any other suggestions for alternate absorbtion materials? I live in the UK so things may be under a different name.

By the way, i draped my duvet over my cymbas and my head and recorded a couple of tracks for a laugh. It did actually make a difference:D. The drums did sound more tight but i'm not for recording a whole album like this. And I thought my room was acoustically descent :rolleyes:
 
Mineral wool or glass wool is what you're looking for...3-6lb. density depending on how thick you're making the trap. Use lower density for 4-6" traps, higher density for 2".

The other options is to get rolls of regular thermal insulation (the pink stuff) and stack it in the corners. Leave it rolled in the packaging. That works pretty darned well, and I've seen people fabricate acoustically transparent screens to make the whole thing look like a floor-to-ceiling bass trap. You'll have to do something different for the first reflection points and on the back wall.

I live in the UK too, so that's why i suggested rocksilk. I've not really found much else here, especially at that price. Travis Perkins sell it at £27 i think. If you find that stuff, i wouldn't pay more than £30. You should be able to find it though. RS60 will be even better than RS45, but it might be more expensive.

Yeah the duvet would help over drums(it's decent at high frequencies(cymbals). When not tracking, you could place the 4 bass traps round the drums, with the duvet on the ceiling (the duvet idea sound dangerous though. Imagine a fire, it'd spread very quickly across the ceiling).

The room might be acoustically decent, but it can always be improved with acoustic treatment, imo. Especially the control room.

Good suggestion. Rocksilk RS45 is 45kg/m3 which is around 3lb, and RS60 is around 4lb. He's on a very tight budget though(basically nothing), so to get 10 2" 3lb panels for £20(around $40) will be his best option, imo. Double up in the 4 corners, half 1 for the sides and 1 left for ceiling is the best idea, imo. Then whatever you can get for the back wall(maybe a duvet, although it'll be a fire hazard).
 
thanks pandamonk, i'm looking into Rocksilk. just a bit heavy going first reading into all of this. Don't you think that dedicated audio treatment (plastic foam tiles etc) are way way overpriced? I know you're paying for research etc but still:confused:

A lot of it is yes. I hate foam tiles. They look ugly and are no better(sometimes a lot worse) than rigid fiberglass traps. This may seem like a heavy read, but you will come out a lot wiser at the end.
 
Go with what pandamonk is suggesting. I built something very similar, they work great and cost peanuts (compared to the same results with prefabricated treatment).

I think I managed to make 1m20*60cm*10cm frames for about £13 each or something like that.
 
I'm going to build some bass traps just like pandamonk with the rs50 doubled, I was also going to build absorbers with the rs50 but came across these;

http://cgi.ebay.co.uk/ws/eBayISAPI....m=350066678287&ssPageName=STRK:MEWA:IT&ih=022

Which would be best for the higher frequency shit? Are these tiles just cheap & not worth in comparison to a few rs50 diy jobs?

I used mineral wool and put the frame on the back and covered it in cloth. I have about $10 or $12 dollars in each bass trap. The room sounds so much better now. Anyone who was in here before notes the difference right away.

I don't think you would get the same benefits from that foam on ebay
 
ok thanks big tom, i'll just make my own
Yeah your own will be tonnes better than that foam. It doesn't even look like proper acoustic foam, and doesn't come with acoustic coefficients. What i suggested was RS45(can you get RS50?). I'd recommend RS60 if you can source it/afford it.
 
http://www.studiospares.com/pd_401982_ROCKWOOL RW3x8 1 PACK PER CONSIGNMT.htm

this looks pretty promising, same stuff basically as rs45?

by the way thanks everyone for helping out, acoustics really aint one of my diamond tipped points <- (_brian_ attempting to relap everyones patience) :D
Hmm, similar, but it's a lot more expensive. You're paying £35 for 8 slabs of 1000x600mm. I paid £20 for 10 slabs of 1200mmx600mm rocksilk RS45. Rockwool might be nicer to work with though.

Go to your local builders merchant(Travis Perkins, Jewsons, etc) and ask about Knauf rocksilk RS45 or RS60. If they say a price over £25 for 10, try and get them down a bit. Tell them about me getting RS45 for £20(i bought 2 packs of 10) from Rowan Timber and say you're looking for something similar. If not, just get that Rockwool. I'm sure it'll be fine.

On a side not, sorry to spam, but are you interested in some good quality but inexpensive mics manufactured by a member of these boards(MSHilarious)? I bought in bulk and am now selling on eBay. If you're not interested, know anyone that would be? They are well reviewed in America, and I'm, i believe, the first in the UK to sell them.
