Treating Studio Rooms - pictures added

My dad and I are fed up with peaks and null in the mix and tracking room in our studio.

We've decided to build 24 - 2'X4' two inch thick traps for all walls and ceilings
12 - 2'X4' four inch thick bass traps for all wall/ceiling corners
2 - 2'X6' portable corner bass traps for placing in front of
window and tracking room door
8 - 2'X7' corner bass traps


We used #2 pine as our wood. We'll be fitting in another frame within the frame (if you can see inside the grooves in the wood) and that will have the grill cloth around it on both sides of the traps.

They should look pretty sharp! they will hold 2 inch and 4 inch thick 703 fiberglass.


I'll keep you posted!! along with a frequency test before and after.


Can't wait!

been there

I just did abut the same thing with 703 and 705, and helped a friend do the same thing.

Here's my advice:

1) Deal with the problems. If you have an 8 foot ceiling, that will be the biggest problem. Deal also with the area around the drumset, and the monitors.

2) Make a lot of movable baffles. You'll find that experimentation is productive, and of course, production problems change each day. I just took those frames and added legs to get them up higher.

3) Do not under any circumstances overdamp the room. It just sounds dead.


4) 90% of the issues will be in the low end, and 705 works better in the low end - so you might want to consider 705. Its heavier by 5/3 - but it works better too esp when things get loud.

My recordings are WAY beter since the treatment,.

Nice

I like wood in studio, wood have " good acoustic property ), but i agree tmcconnell, careful with "death" the room acoustic.
Good way is alternate materials, like wood|brick|rockwool|, oh, you need some diffusors too. You can do yourself, easy.
Good luck

Yes definitely some diffusors. We'll be treating bass/mid/high and first point reflections and ceilings.

I'm not planning on killing the room sound but I'm hoping to kill some of the peaks,nulls and comb filtering.



*saying to myself* I will get a good bass sound! I will get a good bass sound!

Hey Jason,
Are you following the older EThan Weiner Real traps design?

do you have a sketch of the design your doing?

where did you find the 703? I'm having a tough time this go around finding the 703 for my home room.

Hi cz,

I just checked out Ethan's design (I think it's the one you're reffering to) and it's not the same. From what I heard, his traps are excellent but this time we're going to have to make it a DIY experience due to the amount of traps we need and amount of cash we're willing to spend. (Ethan really helped us along the way as for what information he was able to give for our exact room specs - I commend him for that! Thank you E.W. very nice of you)

My dad and I thought of several different ways to do this and came out with the best one that we think will look great while maintaining a strong structure.

I'll post pics of every step of the process. We're still building the frames as we speak. I think by next weekend we'll have one completely finished. (hopefully! unforntunately we're both busy with our day jobs)

The wood is cut with a special blade that makes a groove (picture above) on the sheet which the other frame with the stretched fabric will sit inside of it. We're covering both sides of the traps as well.

As for the 703, I'll ask my dad where he got it. He bought 14 bags of 6 x 2X4X2"

I'm building 7 foot walls ( there will be a gap of one foot on the top, so the walls will not be anchored, thus the walls are more like cubicle dividers...) this is in a two car garage, so the outside walls of the garage will be two of the existing walls, and I'll build these other two- What I'm thinking of doing is using 12 x 1 inch pressboard ( with faux oak finishing) to build essentially bookshelves that will be backed by 703.

so, it would be 8 inches of "bookshelf" then exposed (covered with fabric) 703 2" then plywood 1/4 inch, and drywall . The drywall side will face the remaining garage area, and be used to hang tools, bikes etc.

I'm just hoping that I'll be creating some bass trapping with this set up.
i'll probably throw up 8 mini traps at some point as well- I need this to be useful as a mixing space, without spending a ton of $$$.

Yo Craig,
CSCI in Miramar has em. Look inthe insulation suppliers pages (yellow book).
Thats where I got mine a couple times. They usually have 1" 703, possibly 2, and 3".
Not sure about 705 and/or FRK. I'm sure they can order.

Here's some info I found on DIY skyline diffusors that I posted elsewhere a while back:

Hi everyone. Bill Bairley at bad bear studios in Florida built some "skyline" style diffusors using 1 inch cedar blocks and a proportion grid created by the BBC. I thought someone else might want to use this design so i converted the proportions for this post and made a "precut" list for those of you who want to buy or cut the 1x1's or 2x2's yourself and want to know how many of each length to cut. Here's the proportion grid:

0 3 4 1 2 3 3 1 4 2 3 3
3 0 1 4 2 1 1 3 3 2 1 1
3 1 1 3 1 3 2 2 1 0 2 2
2 2 2 2 0 4 3 2 3 2 1 1
3 3 1 1 3 1 1 3 4 3 1 3
2 3 2 1 2 0 3 2 4 2 1 0
2 3 2 1 3 1 2 2 3 1 3 4
2 0 2 4 4 0 1 2 1 4 2 2
3 4 1 0 1 3 3 1 0 2 3 3
1 3 3 1 2 4 1 2 0 1 3 1
2 1 2 3 1 3 3 2 4 2 3 4
2 4 2 3 3 1 1 2 0 3 1 0

And here's a list of how many of each length block you will need when precutting the wood:

Count of number:

number Total pieces of this length (height actually) of wood

0 13 (no cuts here if you're going flush with the surface)
1 38
2 38
3 40
4 15

Grand Total 144 pieces (131 if 0's aren't used)

These will work with 1x1 or 2x2 inch squares (cut longer depending on the graph number- ie. graph designating number 3 would mean use a 1x3 inch block or 2x6 if using 2x2's)...Here's a link to the original post by Bill (scroll down to message #94333):

Pan60,
You're the F'ing man. I really really appreciate the site with the calculator. Sweet Jesus does that help. I've been using random cuts. Now I can take all that crap into the jam room and build some serious designed skylines for the control room.
thanks again - Matt

My acoustic designer Teale and I did a bunch of tests and found that by sandwiching two inches of 3lb density material between two 1 inch pieces of 6 pound material, you get a better bass trap. You can check them out at the site, we get the upholstery flown in directly from Bolswania. They make some great fabric there.

i was think about using 1/2" soundboard(fiberboard) as the middle of the sandwich. Kinda like a acoustic bass hanger wrapped with poly....????

let me know if anyone needs some kickass bass absorbers. We got quadratics coming too. Those things make a ton of difference in a control room.
