CVRIV's Acoustic Panel Worklog

Update: Never mind about the power and the inputs and outputs. I get it now.

Here's where I am at the moment. I cut all my pieces and cut them in a way that leaves no sharp edges. That means no sanding. I pilot drilled and countersinked all screws to prevent cracking. Each corner is glued and screwed with 2 screws. I have 7 frames complete. Only 7. It kills me knowing I have to make 10 more of these and 8 smaller versions(4" x 1' x 4') for my corner traps. I'm taking a break for now. In about 2 hours I will start stapling the poly fleece to the frames. enjoy.

[cvriv]

Finished doing the back of each panel. I have a make a correction. This is poly felt not poly fleece. This stuff is great. It's strong within reason and has great stretchability. Which is very important for doing something like this. The more stretchability the less creases or folds there will be. looks nicer. This stuff is very breathable as well. You can see the reflection of the door knob and deadbolt through the material in the top right corner in the one pic. Top notch work. Never knew I was this good at upholstery All edges are folded before stapling. For strength. All stables are hammered down as well. Very important seeing that most of the staples doesnt sink in as far as they should. Probably going to buy and electric stapler to do the rest of the panels.

Wow - keep us posted and updated.

I'm not sure I understand what you are saying about 6" x 6" in the corner. So the idea is to basically place a 6" x 6" x 4' column pressed into the corner? The conventional wisdom, I think, would be to either have something bigger than that in the corner (like a superchunk), or to straddle across the corner with something like a 2' x 4' by 4" (or 6", etc.) with air behind it (or fluffy insulation). Of course, it all depends on your room, your situation, and what you are trying to correct / achieve.

I'm interested to hear your thinking on this, as well as others on this forum.

Cool! Looking forward to more updates!

Looks good, but how do you mount to the wall?

[cvriv]

Yea I decided not to do the 6" x 6" x 4'. Instead Im going to make 4" x 12" x 4' panels to straddle the corners. This way there's an air gap and it dosnt take up as much space as a full 2' x 4' panel. Also,.. I know its only going to be 4" thick. The way I see it,... it'll be better than nothing at all. I'm not looking to be super critical at this point either. This isnt a pro studio nor am I pro myself. I'm just starting to learn about audio and making music. I'm making these because well,... I need them. but like I said. Not looking to be super critical. Just want to get these done and get them hung so I can get back to making music.

As to how I'm going to hang these,... I dont know. I have options considering I used a frame. The thing is though that the room I'm currently in has a slanted ceiling on both sides. So to hang them on those walls I will need to harness both side of the panels. Might have to use springs on each side to hold them against the wall. I really would love to try the safe stick velcro stuff on each of the spacers but I dont know if I can trust that stuff.

Anyways,... I have one panel complete. 6 more to go. then 10 more of these and then 8 of the 12" versions. Might haev to wait till payday to finish the last 18 of them. Broke as hell with all the money I spent lately.

[cvriv]

5 done. 2 more to go. Gonna see how much cash I have. Might start building the next 10 right after these. If not i will have to wait about two weeks.

[cvriv]

These 7 are complete. Soon I will start teh rest of them. Im thinking about using some others colors for these panels. I thinking red and brown. Just a few though. To break up all the black panels.

[cvriv]

Progress.

[cvriv]

Progress.

[cvriv]

Finished all 17 - 2' x 4' panels. I just have to close up the remaining 8 - 1' x 4' panels now. Going to finish these tonight.

[OpusOfTrolls]

Nice looking work overall. Those should really kill reflections and mid range resonance, and somewhat damp the bass.

[cvriv]

Thanks. I'm not looking for perfect so these will do just fine. Better than nothing So far,... I have to say that the work involved is the crappiest part about making your own panels. The money saved is great. But hot damn it's a lot of work. Ive got 2 corner traps done. Only 6 more to go. Then it's hanging time.

[cvriv]

Done! Thank god!!!!! Lord have mercy. Going to start hanging tomorrow.

[OpusOfTrolls]

I can't wait to see how you mount these! I thought you were using Velcro? Anyway, double check your measurements and let us know.

[cvriv]

Would love to use velcro but dont think I could trust it:\

[cvriv]

So this is what I think I'm going to do,... for the panels behind the desk that is. Because I have slanted ceiling in the room I'm in now it's kind of not going to be as easy or as pretty as a room with vertical walls.

For behind the desk I'm thinking im going to mount them like this. I have 4 to be located behind the desk. Mounting them like this will cover some of the slanted ceiling and some of the vertical wall below it. My head is leveled where the two panels touch.



My only concern is the amount of slanted ceiling thats not covered by these panels. But,... my clouds will be hanging just above the highest center screen of mine. So it will cover a lot of that space.


Good coverage where I sit.


Was going to hang them like this but I don't think this will be a good idea. A lot of the wall below the slanted ceiling will be exposed. I just thought that because the ceiling is angled down towards me that the reflections would be shot down right on me. But the other way will shield me well.

[cvriv]

So i came to the conclusion that i will not be mounting these panels horizontally on the slanted ceiling using wire. Or just horizontally period. I think the only way i would use wire is if i was to hang them vertically on vertical walls or as clouds. What i think im going to do is save the wire for when i eventually move and for now i will just make some "L" brackets out of angle aluminum. I might be able to get away with only using 2 brackets per panel on the slanted ceiling. We'll see what happens tomorrow.

[gullfo]

maybe put a few vertically on the slant wall space about 450mm apart and a few horizontally on the vertical behind the desk spaced the same. may 3 up top and 2 below?

[cvriv]

YEA BABY! FIRST 4 ARE HUNG!!! Behind my desk Tomorrow I'm doing clouds and I'll start doing the back wall or maybe the sides,... I dont know. So far so good. Looks hot. Had to make brackets to hang these panels on the slanted ceiling. I have the panels overlapping where the ceiling meets the wall because I really really wanted the panels upright. Having them like this covers some of the wall below ear level and a lot of the ceiling above ear level. I made "L" brackets by slicing up a piece of angle aluminum using a mitre saw. I made enough brackets for 13 panels for like 6 bucks. thats 52 brackets @ $0.11 each Buying them premade,... expensive as hell. So yeah. Most of them will be hung with these brackets becaue of the ceiling here but im thinking abou when I eventually move,... should I use them? thats 4 holes in the wal per panel as opposed to a possible 1 hole if I use wire and hang em like a picture. I dont know. I like how they are friggin rock solid up against the wall right now. They are the wall, LOL. Anyways. Let me know what you think.

[OpusOfTrolls]

If you are handy with your measurements and drilling, you could also use magnetic fasteners.

Countersunk Magnets

But their locations need to be spot on, give or take 1/32". Also, they might be difficult to fasten unless you use a screw that is non-ferric. You would also have to miter cut standoffs if you place them across an angle.

[cvriv]

Wow those are cool. I dont think i could use them though. Not for these. All the panels are dlightly off given the type of wood i used. Cheap wood. Lol. Very grainy so all drilled holes are slightly off. Some of the panels are a bit warped because some the the strips of wood is warped. This is why im thinking that when i move ill still ise these brakets because they hold the panels firm against the wall correcting the shape of each panel. They are not terribly off or warped,... but definitely a lot more than im use too. Im very anal and if i spent the time i usually spend doing stuff,... these panels would be no where near done. I really needed these done so i can can back to learning music.

[cvriv]

Need opinions. I have 4 panels allocated to be used on the back wall/ ceiling. Do you think i should span them out across the back wall or center them side by side like the ones behind my desk? Centered side by side leaves 5' uncovered areas on each side. I know the uncovered area amounts the same if the panels are spanned out but,... the panels are spanned out. So what do you think?

[OpusOfTrolls]

You should space them a foot or so apart, oriented vertically.

[cvriv]

Ok will do. Theres going to be a 1' trap in each corner as well. Should i have spaced them apart like that behind the desk too? Each side wall has 3 panels. I was going to put two of them together at the first refflection point using the mirror trick and then have the third centered within the remaining space. I was planning on hanging 3 of them directly above where i sit. Should i span thise out and center them in the room too?

[OpusOfTrolls]

The panels behind the desk don't need to be spaced. The spacing is for letting some reflection back, because you don't want all of it from the side/rear corners.

Another thing, you don't need to mount them in the middle of the wall, vertically. You can also raise them up and they will catch more reflections from the ceiling.

[cvriv]

Ok thanks. So the idea is to have some reflection an even amount from all angles? The clouds should be centered and space or side by side above me? I have seen big clouds right above drum sets and workstations thats why im asking. Thanks for your help.

[cvriv]

Damn so i just read that the front wall doesnt really need to be treated!?!? I see pics of so many studio with front treatment though.

[gullfo]

spacing the absorbers can help - the gaps and edges help and you can get more coverage of your space. yes a lot of rooms use treatment up front even though the back wall is very important as is the ceiling and side walls, desk reflections, and floor
