building room treatments?
« on: June 13, 2009, 02:09:47 PM »
Anyone built their own? In my basement the couch is against the back wall and it's a concrete wall with nothing more than a coat of paint over it - ouch! Luckily I have a big fluffy couch with high cushions but I still need something there.

I'd like to build two treatments to hang side by side on that wall. I'm thinking 24"h x 48"L and use the Owens Corning acoustic insulation.

It seems like a fairly simple project. My questions though are
1. How thick to make the treatment? That wall is about 10' from the speaker drivers. Is 2" sufficient?
2. What to fabric type should I use to cover the treatments? I'm guessing something like a low thread count cotton would work to let the sound waves penetrate the fabric and be absorbed by insulation but I really have no idea.

I use both 2 and 4" for the panels I've made. 4" behind my mains, 2" on the walls. I made simple wooden frames covered in muslin fabric. I'll be happy to e-mail pics if you'd like.

Yes.   Room lens clones and panels.

The panels are 2'x4'x2" pressed fiberglass in a pine frame with burlap stretched over them.   I mounted them temporarily on a plank so I can move them around the room but if I didn't have WAF issues they would be hanging on the wall.  The whole job took about 45 min not counting the time to shop for fiber glass and fabric.

The room lens clones are from the jon risch recipe.  I made a temporary base using plank and right angle pipe ends.

Thanks Mike, that's exactly what I'm looking at building. Going to get them as much GAF as possible by breaking it up into 3 pieces with a color "theme" so they look a little more decorative than standard wall treatments.

Here's yet another site I was wandering about on last week with extensive room acoustics info including calculators for building your own bass traps & diffusers of all types.  I downloaded a little app that calculates the effective frequencies and lumber cuts required for building QRD and skyline type diffusers.

Here are some links I had saved when researching this a while back:

Some of them sell the insulation and provide kits for DIY.

http://www.readyacoustics.com/
http://www.realtraps.com/
http://www.atsacoustics.com/
http://www.gikacoustics.com/

If using the passive panels it is best if you leave an air gap between the panel and the wall. The more panels the better. And it is better to use the denser OC 705 vs the OC 703, and thicker is better.
Keep the back open and let the waves pass through. Most people I think make a smaller frame at the back and then attach the fabric to that frame with staples or upholstery tacks.

Ethan Winer is associated with Realtraps, but he published this article in 1995 in Electronic Musician.
http://www.ethanwiner.com/basstrap.html

These panels are sealed and work using a vibrating front panel concept. Inside is a fiberglass panel that dampens the vibration. You might think about this design as it might be more effective with your cement wall. He uses alternating different wood panels for differing lower frequency ranges.

Here is another room mode calculator. This one is more visual.

Looks like I can order 3 of the 24x24x2 panels from here and have them delivered all for less than $100. At that price I'm not sure it's worth my time to build them. Shipping on the acoustical foam/insulation is not cheap, add in my time and aggravation I'm leaning towards ordering a set.

Any thoughts?

If I remember correctly, I built my 8 panels for around $150 (maybe a little less).  I found a local place that had rock wool, so no shipping was involved.

I did a cursory google search and I can't find the name of the place that I bought the panels from (industrial park, north KC, couldn't drive there again).  I was hoping to find a clue to help you find a similar place locally.  I know home depot/lowe's didnt' have it, and the place I bought the panels from was a wholesale construction biz that specialized in commercial HVAC & fire stuff.

I bought panels manufactured by Knauf.  They are the same as the Owens Corning panels that the DIY sites describe but I couldn't find OC in stock anywhere around here.   I wrapped the panel in batting before covering so that any stray fibers couldn't escape.

http://www.knaufusa.com/products/commercial__industrial/pipe_and_equipment_insulation/knauf_insulation_board.aspx

They also make a nice collection of rigid pipe that can be used for making bass traps.  Just seal the seam and cap using construction adhesive.

http://www.knaufusa.com/products/commercial__industrial/pipe_and_equipment_insulation/knauf_pipe__tank_insulation.aspx

You should be able to find this stuff in Denver by calling any commercial building supply house.  Call Knauf USA and they will tell you who carries it if you can't find an obvious source.

Batting is the polyester fill used in quilts and padded things.  It comes in various weights.  I used the thinner stuff.  You can get it at any fabric shop.

Nope..it's like a roll of flat cotton ball.  Think the inside of a quilt. 

There is a pic of mine covered in batting here (same link as above):

Let us know how this works out, whichever route you take.  I'm thinking of putting rockwool panels behind some some existing canvas paintings and mounting them out from the wall several inches once I redo my living room next year.

They're all out of whack now, because she retook the room,..... but prior to that, she'd made some hanging tapestries out of a tapestry fabric (of her choice) and batting; and they were really quite functional at first (before the retaking of the room). They're thicker than a normal tapestry, and have a better WAF rating than thick monotonish wall stuff (baffles).
Beyond that, we have not done much sound tuning.
I've got about a million things that I'd like to do before sound baffling / room tuning (like buying a large enough house with a space that I can dedicate to audio ecstasy).

I went ahead and ordered 3 24"x24"x2" panels from ATS acoustics and I picked them up this afternoon. Got home a bit ago and am playing with placement on the wall behind the couch. I can hear the difference, highs are of course tamed a bit and the image is cleaner. I'll do some serious listening this weekend but I think this was a good move.

Michael was over this last weekend as he happened to be in Boulder sp he can attest to how lively the basement is, especially with half-a-dozen drunk assholes packed in ;D

I paid less than $100 shipped for 3 panels, I couldn't build them for much less than that and factoring in my time this just seemed like the way to go.

anyone have any thoughts on placement? I have 3 separate panels that I'd like to place on the wall directly behind the couch. Should I space them relatively close together, say 1", which would give me coverage along the seated portion of the listening couch or should I space them out a bit farther? the couch is on the long (20') wall, basically centered.

i need a cheaper solution.  ive got to much wall to cover.  it would be cheaper to carpet the walls than buy panels or raw rock wool to cover them.  im looking at 12' on the wall behind the spekers and 20' of the right side wall.

you don't need to cover the whole wall, especially on the side. you need to cover the 1st reflection points. you can find those by sitting in the listening position and have someone move a mirror along the wall, when you can see the speaker drivers thats a reflection point and you need to cover it.

my reflection point is long because ive got a listening couch with my computer desk right behind it.  ill work with my recordings at the desk and do general listening at the couch, basically an extended sweet spot hence the long wall.   

......and the wall behind the speakers is painted concrete.   ::)  this room has more bounce than corey's checks.

you don't need to cover the whole wall,

Nor do you necessarily want to.  I've read that a mix of hard and soft is the way to go, so that you don't necessarily have a too live or completely dead room.

If memory serves, you can make your own wall treatment by framing fiberglass insulation behind speaker fabric.  You would alternate those panels between the finished (hard) materials.  Does that make sense?  You build a frame of 2x4's, fill it in with something that will absorb sound, then cover it with acoustically transparent fabric.

Sparkey beat me to it..

Focus on the primary reflection points like Tim mentions- walls and floor (rug w/under-padding at the reflection point) and possibly ceiling, depending on how far you care to go with it.  From what I understand you don't want to cover too much wall with thin-ish absorbers, or the top end gets overly absorbed and the room sounds overly dead, like a badly treated garage band rehearsal space with thin foam everywhere.  I hate those spaces.  I like a more lively, though controlled room.  I've played with putting couch cushions up on the back wall at the reflection points in my room and I don't like it, kills the 'air' and the sense of depth in my room.  You might try that just to get a feel for where you're going with it first.  You might find just hanging a bunch of stuff on the wall or sticking a book case or something there works better by diffusing the reflections off the wall and breaking up slap echo between facing walls. Diffusion kills slap echos and specular reflections without reducing the reverb time of the high end.  There are also combination diffusive/absorbing materials and ready made products.

Its the bass region where you really can't get too much absorption (bass trapping) in a small room.  Both because it takes more to do the job and because bass end absorption is big and expensive.  Too much thin absorption on the walls can actually work against you by damping the high frequency reverb without effecting the low frequency, exacerbating typical 'small room' bass problems.  Solid concrete walls don't absorb much bass.  Windows and doors will act as bass traps somewhat, passing the low frequencies and reflecting more mids and highs.

Once I get around to it, I'm thinking of building some nice looking wooden diffusers for my back walls (diagonal room setup) and scheming ways to build some 'dead air behind rock-wool' low frequency absorption into a couple room corners where they'll do the most good.

You all might enjoy a great write up on the full process of designing and building a full-on mastering suite in Amsterdam with excellent photos of the whole thing over at Gearslutz.  Notice the skyline-type diffusers at the ceiling reflection points and across the rear wall behind the client couch.  There is also loads of absorption in the sidewalls and ceiling and a massive bass trap built across the whole back of the room hidden behind the diffusers, but then the entire room is purpose built and floating.  Worth a look to see what goes into a full-on, purpose-built mastering suite (also interesting and informative in its professional music focus, in contrast to all the home theater pr0n on the web)

I've heard many great things about those DIY tube traps but can't really get away with them in my room. If you can, I've read that stacked rolls of ordinary fiberglass house insulation batting work very well and require zero DIY construction other than transporting them from the store and stacking them around the room.  They are already compressed and held in barrel form by the plastic wrapper.

Of course those batting rolls are large diameter and ugly, but can be an easy proof of concept before building something nicer looking.  My house looks like a construction zone anyway, so maybe I should try it.

that's a GREAT idea

some sort of tube traps are next on my list and I've been wondering about how to do it fairly simply. I'm ok with diy projects but really dislike doing them, I know others really enjoy it - I hate it.

Remember that you can over deaden a room. 

Some thing the try is cut one panel into triangle shaped pieces, cover with fabric that will blend in with your paint scheme and mount them in the ceiling corners.   Mount a few flat panels on the wall.  Then frame the remaining panels with a pine frame that can be covered and mount the panels to some wooden stands.  That way you can put them in place (or try different places) for critical listening and then put them away when the wife gets back in town.

I have mine mounted as free standing panels for the exact same reason.  I can take pictures if it would help but all I did was use drywall screws to fix a little rectangular foot to the bottom of the framed panel.

I'm not the one to speak of/to the details.
The person who owns the system has been tweaking it to get to that point for the 6 months or so that I've been a member of this other audio forum (a forum dedicated to turntabling).
His room is incredibly small, and he sits on the floor about 2->3' to the right of the picture. He claims with these tweaks that he has created a large music hall (he listens to classical and chamber music almost exclusively).
He claims that even the rooms color, and the color of the wires comes into play in tuning.
I can provide a link, but, you have to be a member of the forum to have access to that area (members only area). So unless you sign up, a link is worthless (there is a wait for new members, while the mods verify).

I chuckled at first as well; then over time, the theories have revealed themselves, slowly, through comments made in other threads, and, in part, by other people.
One of the most logical arguments that I've read is that the birdhouses act as the part of resonators, with the frequency dependent on the size of the box and port (bird entrance hole).
I don't know ::shrugs::, and I do not know enough to say anything one way or the other.

One thing I do know, is that every time that I've brought up room treatments for my space, I meet up with the my living room, and, you owe me a bigger house before you even think in that direction; then you can do anything that you want in your listening room.

So around my house, sound treatments amount to a fat negative WAF rating.
She did make some wall-hanging tapestries, which I guided her to mount behind the couch on the backwall (my listening spot).

i think my wife digs all this (other than the expense of it all) but wont admit it, so the WAF is usually able to be obtained with comprimise.

......and the occasional "fuck it ill do what i please". ;D  it is the MAN cave after all.

She seems to be OK with some of the floor to ceiling wall panels.

Man Cave?
Its in the living room, in a small house. My footprint there is massive enough without pushing the limits.
My fuck it and I'll do as I please credits have been long ago used with mics/pres and recorder purchaces; speaking of which, i still need to replace my R09 - see where I'm going??.

Mike, my living + listening room situation is similar.  Perhaps you can leverage Jim's seal of approval to assuage sarge's concerns. If you ever find yourself with a dedicated 'Man Cave' for music listening you can then apply for one of these.

If I had that much money I'd at least have a comfortable listening chair :P
I’ve had a few weird experiences and a few close brushes with total weirdness of one sort or another, but nothing that’s really freaked me out or made me feel too awful about it. - Jerry Garcia

HAHA!  i thought that too, but it is in europe after all....


i ordered 12 more 2x24x48 panels of OC705 & 6 of the 703 yesterday.  i plan to make 6 x 4" broadband bass traps, plus fill in the corners with triangles and make a solid back wall and ceiling treatments. 

and FYI, a local suppler can get the panels at half of what the best prices i saw online, and no shipping fees.  it was such a bargain i had to do it.
