Hi! I have tried to make a rough copy of how my studio looks. Sorry about the amateur look on the drawings(paint). But I think you will get an idea of how it looks. I want to make my room less 'reverby'. I am not after making the room soundproof at this moment. Just want to make it acoustically better. I want to get such on the walls as shown on the picture:

But I was hoping anyone of you can tell me where the best placements are for this? (i have drawn some orange boxes of where I was thinking of putting some) Please let me know what you think of this.. And here is a picture of the room, from above/top and from the front. And I also hope someone can tell me if my monitors are correct placed, and how about the subwoofer, should this be in the middle or in a corner? Please let me know if you need more info, and also if you think this idea is good. thank you very much for all helpful inputs!! NB!!!! : i have no clue on how I can make the pictures smaller in size. Sorry about the big size!! Krister
Aloha Krister, Welcome to the forum! :D Any chance you could edit your profile to include your location? This is very important, because this is a worldwide resource, and as such, material costs and availability vary widely. For example, masonry is cheaper than gypsum in some parts of the globe, whereas it's the exact opposite in other regions. Thanks! :wink: Have you read: http://johnlsayers.com/HR/index1.htm for some DIY wall absorbers and traps? They are for acoustically treating the room and not "soundproofing" the room from sound entering/escaping. In regard to resizing your photos, try these. (you may want to delete your pic attachment and use these) Hope these help. Aloha 8)

*updated location* thanks for resizing the picture! It looks good the absorbers that where explained at this link, but it looks hard to build(or are they avaiable in stores?). I don't fully understand all words when I look on the explanation of them. Like insulation. Is this the same as the isolating material which is also made by glava? :D thanks
Aloha Krister, Thanks for editing your profile! :D While there are products available for the acoustic treatment of your room, most of what is described on this forum is of the "Do it yourself" (DIY) nature. Like you, I found the information hard to understand at first, but as I continued to read and study, it got better. There is a lot to learn, but the time invested in learning some of the principles described is well worth the effort. Take your time, read, and dont be afraid to ask questions. Most of the people here are very helpful. Also, chances are that your questions have been asked before, so try using the "search" function at the top of the page, as well as checking out the "stickies" and "reference sections" in the design and construction areas. You can check the Building Material/Products section as well: http://www.johnlsayers.com/phpBB2/viewforum.php?f=6 to see if someone else has already touched on this subject. I looked up the "Glava" product line and it appears that they might have what you need, however, being that all of the info was in ?Norwegian?, I can't say for sure. Perhap you could contact Glava or a sales rep and find out more info. What you need to look for is either rigid fiberglass, such as Owens Corning 703 (un-faced) or rockwool, mineral wool, somewhere between 2 to 4 pounds per cubic foot density (pcf); Johns Manville and Knauf also make similar products. If you're interested, you might check out my threads: http://www.johnlsayers.com/phpBB2/viewt ... ght=#15598 and: http://www.johnlsayers.com/phpBB2/viewt ... sc&start=0 You can see how I started out having similar questions and the type of direction given. Looking forward to following your posts and progress! Aloha 8)
As Kendale wrote already: welcome to the board! Adiing a couple important things to what Kendale wrote, the more you learn, the better the design will be in matching what you want and what you acheive with what you spend, studo construction is 90% design and 10% building, and design research is about not having to ask the question "can I afford to do it again right this time?"

Aloha Krister, Let the reading begin! :D
I want to make my room less 'reverby'. I am not after making the room soundproof at this moment. Just want to make it acoustically better. I want to get such on the walls as shown on the picture(foam).
While applying foam products may decrease the high frequencies, more often than not, it leaves the room sounding somewhat "boxy." This is in part due to the fact the problematic low & mid-low frequencies are mostly unabsorbed by the foam and are still bouncing around the room. Excerpts from the SAE Recording Manual: http://www.saecollege.de/reference_material/index.html
For an instrument to sound good you must hear a balance of its high and low frequencies. If your room is too dead in the high frequencies the instrument sounds lifeless and tubby, whereas if it's too live in the high frequencies the instrument sounds distant and has no presence. To balance a room you must have a true balance of the high frequencies and the low frequencies with the right amount of deadness to liveness.
By using different construction techniques it is possible to treat the walls so they absorb sound at various frequencies.
Most home studio enthusiasts only seem to treat the high frequencies in the room yet it is the mid and low frequencies that cause all the room problems.
Attached are a couple of pics from the SAE site. The first pic is what I was listening to (and more than likely, so are you) before going with soffits and absorbers. Very tiring to listen to, let alone trying to mix in. The second pic is kind of what I'm shooting for, albeit in a modular sort of way. I opted for a front wall absorber instead of the window as suggested by Steve (Kinghtfly). Granted, the added expense and work involved may be somewhat daunting, but in my case at least, the end results more than justify the investment. I would encourage you to keep reading, asking and saving up for your project as best you can. Looking forward to your progress and pics as you get started. Aloha 8)

Aloha Krister, Here' a couple of diagrams on the "modular" approach I was referring to. The first is from the SAE website, and the second, a variation and the approach I chose to take. There is also a plan for a "cloud" absorber which is not shown. Currently, the front absorber and both left and right bass trap/speaker soffits phases have been completed, with the side wall absorbers in process. Listening Test: First Impressions - bottom end is tighter - imaging is clearer - drums sound clearer, more defined in mixes - able to hear clearer at lower volumes than before - room sounds quieter without music playing, louder & tighter with less effort when music played - less fatigue/more enjoyment in listening to mixes! Hopefully, as you read this and other posts on the forum, you will be encouraged to work past the effort, questions, budget constraints and what if's as the results can be quite remarkable if the design and construction principles are done properly. Aloha 8)

hi! thanks for the useful information! i have a picture of how my room looks now though. I am planning to try to build some amateur basstraps. i've read some about this. so my plan is to get some rockwool and make a frame of wood with some kind of cloth(any ideas of what kind is good to use here?) to cover the back and front to prevent the rockwool for making bad enviroments. Got the idea from this site somewhere, where this was described very well on how to make(mikesproject i think the tutorial was called): These I will place in each 4 corners of my room, which will cover the most from floor to ceiling. maybe build an extra wall that I can move around in the room, so I can have behind the listening position. will this help? :lol: i am also planning to buy some traps from realtraps for early reflections.

Aloha Krister, Nice pics! Clean setup! 8)
any ideas of what kind is good to use here
I think the Guilford of Maine/Interface Fabrics products are the standard fare: http://samples.interfacefabrics.com/ and http://www.silentsource.com/acousticore ... hart1.html but I've heard of people using muslin, weed cloth, and burlap, but mostly something with an acoustically transparent weave that would allow sound to pass through without reflecting too much. Any chance you could resize your pics down to around 700 pixels wide or so? This will negate having to scroll left and right and is part of the forum rules. Thanks! :wink: Hope these help, Aloha 8)
