some pics of the super chunks...they will be mounted 2" or maybe 4" from the corner...












I decided to try making them this way instead just filling the corner...

According to this article...

Acoustic Treatment and Design for Recording Studios and Listening Rooms

Quote:
Foam blocks like this are meant to be mounted in a corner, stacked one above the other from floor to ceiling. When measured for absorption four of the five surfaces are exposed, but when installed as intended only the front surface absorbs. So in practice, a two-foot corner wedge like this provides only 65 percent of the absorption claimed. The shorter the wedge, the larger the disparity between the published and actual absorption.
so, if you have more material, but 2 sides of the triangle are up against the wall....it seemed better to me to have less material, and place the triangle away from the wall, therefore 3 of the 5 sides are exposed instead of 1. When you build a panel bass trap, you dont close the back off right? The panel bass trap does it absorbing through the back, because the back of it faces the corner..unless im mistaken?

also, i have hard brick/plaster walls....i would think that since its hard, its not going to absorb hardly anything at all as compared to wood/sheetrock walls....hece i think the way i did it is better to absorb...

Anyways, chunks arent "traps" technically right? So with my design, its like a combo of trap and chunk...

or maybe i just think too much?? lol

Anyways, we will see how they perform. They werent not difficult to make, i can always change it later.


i stole this idea from post # 754...just changed it a bit.

Yes

I want to point out that those will help, but really the face should be no less then 24". Yes you are spacing it away from the corner so "maybe" your ok. You would need to test the room before and after to really make sure. Basically it looks like you build tube traps but made them a different shape. If it does not seem to work, you can always line them up across the back wall. thumbsup

No way was i going to have room for 24" even if i filled the corner, i could only do a 17" face...unfortunatly i have eletrical outlets , a window and a hallway all near the corners...

So now, i have an 12 inch face. But heres my point, since the other 2 sides are are now not closed off...why cant i just add all three sides togther? 8" + 8" + 12" = 28" ??

According to the article, a 24" face is not absorbing as much as you think it is....

Anyways, like you said, the room need and analysis before and after..which i plan to do...so well see what i get....

Also, later, since i cant continue all the way to the ceiling with these things, i think im going to build little 1' x 1' or 2' x 2' panels to go across the tri corners, so that will probably help..

That article is talking about how it was tested in the lab and to be honest with you I don't totally agree with 60%, but he is right because it was not tested in the corner. It really is not talking about the 24" face. His point is the reason I was saying you NEED 24" across, as you need to pick up as much sound as possible. With all of that said you spacing from the corner will help A LOT because the low end absorption comes from the distance from the face to the corner. Meaning the the further that the face is from the corner the better it will work.
Understand what I mean??

Great work, I love the cloud. I hope to do something similar myself.

Seeing as you're now an expert in cutting mineral wool, given the million
triangles you just cut, may I ask what tool you used for the cutting ?

Glenn: yep, i understand. good stuff on the whole face being farther the better from the wall thing...didnt know that thumbsup

Frank: thanks

Paul: Yes, it was cutting triangles for daaays....the frames i built have 3 triangles that are made from MDF. I used an extra triangle as a template. i just put the template up to the mineral wool and used that as my guide. i ended up wasting one 2'x4' sheet worth...probably could have figured out a pattern so didnt waste any...but i only paid 3.30 euros a sheet..so i can afford it. I used an electric carving knife, ya know...the kind you use at thankgiving to carve the turkey...got the idea from this vid ( although i didnt pre-cut with a utility knife like he did)

Very nice, sir. Your thread has been an inspiration to me, that we can make DIY acoustic treatment that looks good enough to not "uglify" our rooms!

couldnt agree more...

for myself...DIY was the only option due to cost reasons...how many people have the money to pay someone to do all this?? not many.

Maybe when im rich at some point in the in future...ill have a professional company build me a real studio heh....but for now, this'll do.

im going to be done sometime this week...you wont believe how good its going to look...it already looks good and i only have the bass trapping up.

I built everything myself, all the acoustic treament, my desk, speaker stands...about the only thing i didnt build in the room was my bed.

ill be making a short vid giving a "tour" of the studio when its complete..rather than taking photos because they wont do it justice.

2 months of hard work is coming to a close...

stay tuned.

i thought i would post up some pics of my progress, since i learned from reading older posts...i always like looking at pics too

mounting system for 3 of my six 1st reflection panels...

stole the idea from here..( post #9)

mounting acoustic panels

heres the panel receiver



small nail to adjust the distance of the panel from the wall and to make level adjustments



brackets i used on both sides to keep the panel from moving sideways and falling off in the event of an earthquake or if it gets bumped.


wall receivers in..i painted them the same color as the wall when i was done.



Heres the heavy dity mounting system for my ceiling cloud. looks like im about to hang big chunks of meat from the ceiling lol

50 pound cloud is Mounted via 6 hooks on ceiling and 6 on cloud... there is 6 extra hooks on cloud and ceiling for backup...redudant system in case one fails, the other catches it..nothing like living in earthquake central....

well its 99 percent complete..just gotta do some touch up, and and one more layer of fabric on the red panels then trim the excess fabric...

The room sounds FANTASTIC....flutter echo is nearly gone...and the absorbers just eat the bass...

after all this work and the pictures come out like crap... they even do it justice..its one of those "gotta see it in person" things...

im still gonna take a vid..maybe that will come out better

heres the two 1st reflection sidewall panels mounted on hinges so i can get to the closet







corner chunks blend so well, can hardly see em...





No camera flash...

What size are the holes in the panels? Also, how did you get the holes so even and straight? Did you trace around something?

cool, so it's groovey home studio/high end listening station setup... have fun man! looks like it's going to sound great.

where's your hotel located, looks sweet--maybe i'll check it out on our next vacation in the neighbourhood! (actually our second next vaction, off to lisbon with the wife next wknd...)

after reading this a second time i understand that u are basically flipping the "superchunk" 180•'s so the two sides are exposed rather than the one side? Sounds like a great idea.

the holes are 51mm. if you look back in the thread, you can see where i laid out the pattern. i bacially figured out how many holes of that size i could fit on a side, drew my centerline, and laid each hole dead center, using the hole saw itself as my template. The hole saw has little notches/holes on the top if it, which i used to center in the centerline i drew.

no flipping was involved...it sits in the corner like a normal superchunk...just has an air gap..and the frame is open.

i havent seen it done like this before ( and i have read a lot of posts on here)....

I think they work great.....i havent done a room analysis with REW, but i plan to.....but think i have a good ear, and it tells me they are working very well.

L = 13.9ft W = 9 1/2ft H = 9.9ft

No unfortunatly no befores....i know i should have done it...but i needed time to learn REW and i wanted to get it finished. Wasnt going to really matter anyways because i was going to install what i made no matter what. heh REW will just help me "fine tune" the room.

Anyways, i kind of like the old school method of using your ears and SPL meter to determine the sound of the room...

I can tell you the sound of the room is just amazing. My friend and my father who have been in a lot of studios over years, agree about the sound.

I'm just overall happy with it.....but i will post up REW findings when i do it.
