Ok, i have found where i can get polyester fiber, i can get in two styles, loose , and from a roll about 12mm thick, so was intending to use the bags of loose and open it out a little and do the best i can evening it out for corner traps around 24 inches by the hight of the room filling the whole void, then use the roll layering till i have the desired depth for my wall traps...im not doing any reading for the room atm as it a short term fix just to get the room workable for some rough mixing. But i just read ethans reply to somebody where they ask about the same thing, and ethan says the heavier the better, so im a little lost now with, not being dence, but being heavy, but breathable, so back to my compression question, what would you say about compressing the polyfill?...light med or heavey compression, or leave it to settle on its own?....i think the polyfill is going to be my best and only option, unless anybody has any last advice before I commit to my plans? I am so grateful for the advice so far so thanks, allso if anybody is willing to come up with a design for my mixing room given the issues i have with materials i would happily pass on the dimensions along with any other info you require!....Cheers PPP....π

For density, under between 4" to 8" thick higher density is more effective. Greater than 8" to 12" lower density is lower cost per unit volume while performance is only either slightly less to somewhat better (not sure about the latter).
Going with the deeper (thicker) bass traps is almost always better if you have the budget and space available.

Ok, so im going ahead with my polyfill treatment, next question is. I've decided to swap around the rooms so im going to be starting the mixing room next. Due to some doorways being close to the corners of the back wall, (what im intending to be the back wall) please correct me if this is a bad decision, the bass traps there will be half the size of the traps at the front of the room, facing the monitors, so as the doors will be in constant use, i don't really want to build free standing bass traps, im going to build them into the corner, OR, my other option is to use the other room which is nearly perfectly square with a 9' ceiling...
so question is, which room would be best option for the mixing room?....the slighty more rectangular room (only by 1 meter) and have the smaller bass traps at the back of the room....bass traps at the front would be around 4' across the corner of the room, and around 2' at the back of the room Or the square room...where i could build equal size bass traps?
The rest of either room will contain 4" or 6" absorbers on the walls with an inch or so gap between them and the wall. and i will be covering the ceiling a good 70-80% of it with with 6" traps suspended with a 3" gap between them and the ceiling. The floor is tiles with a thick rug taking around 70% of the floor space, or i do have the option of heavey duty carpet tiles and cover the floor?.....any suggestions??....cheers allπ€

Acoustically treating a square room is like using spoiled flour to make a cake: you're better off starting with better ingredients. Open doorways are almost like bass traps, depending on what's on the other side of the door. Please post a drawing of your room and where you intend to place your traps. Include their thickness and the room dimensions.
Thanks.

Cheers Hexspa, the bass traps would be, guessing with rough measure measurements, 120x80x80 at the front of the room. And 60x45x45 at back of the room. Both by 3 meters highThe wall absorbers would be 100x185 by 6" and the ceiling absorbers I hadn't really desided on, but they can be any size, im going to make them all myself filled with polyester fill so can be any size they need to be, i may need to change materials on the ceiling if i think theres a problem with weight, but think im ok.... There is also a alcove at the back of the room where i was intending to do something?....build some cupboards also with absorbers on the doors...all made with 18mm MDF....maybe, or a giant defuser, im willing to spend the time on this room to get it as good as possible.
i sent some pictures of the room, the patio doors will eventually lead to another room, im not intending to leave them there, but would need to leave room for a doorway, i could leave the whole thing open plan, but thats not really my intention, unless the mixes sounded so amazing it made me cry!....

Another picture here. oh and the black triangles in the drawing in the corner of the room are my bass traps! sorry for the mixture of measurements and rubbish drawing...all ceilings are 3 meters high....if i needed to shape the room to could possibly do this also...but again, only if there would be significant difference in sound quality... I write instrumental spacerock mixed with ambiant textures and dub, im a solo artist and the studio is personal to myself, money is an issue but not time or other people, i will open to the public free of charge so many days a month, but my guess this will be mainly just singalong to backing track type stuff. I Am also toying with the idea of a musicians hideaway, as have palns for accomadation, a kind of a writers retreat/rehab, but have yet to work out how i bring all the rooms togeather and also give myself the privacy as need music in my life or i don't function! So its all a working progress, ever changing!....there would be a pool and gardens and privacy along with private writing rooms and acsess to the main studio acording to the guests requairements , so thats the general direction.....

This is but one casual observation... about those little right triangle basstraps by the doors. They don't have to be right triangles. If you are using 24" x 48" panels, you can adjust the 24" face of the panel to straddle the corner and clear the door.
In general, small spaces need lots of absorption. You really can't over do it.

Hi PPP, Here are some things I've seen and read that may help. Please note that I'm only a novice, without much experience, so these are just ideas, not advice. Having 2 square traps mounted in each corner, forming the two sides of a right triangle, can also be effective. If you mount a trap on each door, and then another on the wall perpendicular to the door, that would give you more absorbent surface area than the small right triangles. If the traps were thick enough (4 - 6 inches? or maybe 4" with a 2" air gap behind them?), this may be a possibility for the 2 corners: ...but that plan could interfere with the bottom door. here's another idea that may work for the bottom door: www.youtube.com/watch?v=MkZgBc_LLaMit looks clever, but I haven't tried it yet, or seen anything else about it, so don't know how well it performs. I plan to try it on my own door when I can. Thanks, -d

Thanks both, that really gives me something to think about, that door design on youtube is quite nifty....appreciate that drawing also deanm cheers...giving me the idea of making the whole doorway slide...Or considering blocking it up later, ive already blocked up two doors and a window in that room.....thinking about a two stage build now with short and long term plan....π

I can only say two things: bigger superchunks are better than smaller and I hope your polyester works. The size you have planned for the front seems great but the rear ones seem on the small side. These guys can really make a difference in your decay and I consider them pieces as opposed to the pawns of panels. You can also consider a Live End Dead End design where you heavily treat the front wall with several-feet-thick absorption and make the rear wall diffuse. You have a beautiful room so now I hope it gets the sound to match!

Ok Hexspa, cheers , thats kinda what i wanted to hear, i need that boost in confidence to start and make some final decisions, i hear what you say about the polyfiber, but my thoughts are, if there is a problem, at some point i cound just change the polyfill for something more substantial, as the hard work building the frames would be already done. Just a lot of messing about. Also after ive made up the frames im going to have a dry run without the polyfill so i can get all the fixings drilled to get the messy work out the way and clean up before a final paint. So maybe theres time to stumble across another fill. But i have high hopes with the polyfill, as without having any real knowledge, givin that im told its ok to use, when i feel it and squash it!, i can kinda imagine in relation to other materials its going to be ok!....

Clever indeed! It really needs to scaled up to a 2' wide panel but that should be possible. I don't have a need for that kind of trap but for anyone who does, it would be worth the "head scratching" to make it work with the wider 24 inch panel.

I have exactly that need in my room here, so it's in the plans for me. Scale it to 2' face and 7' tall. Due to budget and health reasons, though, things move glacially in my room, so it'll be a while before I learn any results.
*scratches head* The wider the hypotenuse gets, the longer each right side gets too, which means the trap could consume usable wall space when it's stowed, instead of just fitting neatly behind the door. Hmmm.

True, there are trade-offs. But as you point out, panels mounted on the door and adjacent wall is also a good solution.
I'll just repeat here, let's not forget there are 8 other corners to position bass traps (12 total) in a rectangular room. Just sayin'.
