Today we're back with Music City Acoustics to talk about how they build their acoustic panels 👊 What is your next DIY studio project? Be sure to check out the last video we did with Music City Acoustics all about common questions when it comes to studio acoustics th-cam.com/video/0uq7CJE_gW0/w-d-xo.html
I dont mean to be so off topic but does someone know a method to get back into an Instagram account? I stupidly lost my account password. I would appreciate any tricks you can offer me.
@Royce Johnny i really appreciate your reply. I got to the site on google and Im in the hacking process atm. Takes quite some time so I will reply here later with my results.
Hi RJB, on a small scale yes it would be. However, when making panels on a larger scale there are a couple of reasons making the frames larger is not the best option. 1. When building the frames, we would have a ton of wood waste. With the dimensions of our frames, we have almost zero wood waste. The mineral wool is made of 70% recycled materials, so while it is unfortunate we can not use all of it, the waste doesn't have the same environmental impact. 2. If we were to make the frames larger, they would be 49.5"x25.5" making them significantly harder and more expensive to ship to our customers. Hope this clarifies.
@@MusicCityAcoustics I was wondering about the approach too, and it makes perfect sense. But that creates next question: can't wool offcuts be squished down in some mesh tube (wrapped in cloth again) to make some kind of low cost bass trap? Or would it be to much work for the potential turnup?
For anyone wondering about the nail-gun, you don't need one. If you want to make an uber good looking one that offers slightly better performance in the low end, here's what I've done: Get a $20 pocket-hole jig and some Tight Bond II wood glue. Pocket hole screws aren't strong but they'll hold it together for the glue to dry. That particular glue is stronger than wood itself, also join the short pieces to the face of the long ones. The benefit of this method is it lets you keep the joinery on the inside with no visible screws or nails on the outside, and you can apply wood finish to the outside frame which looks really nice. The other caveat is if you use plywood you have exposed edges which require iron-on laminate strips ("edge banding") before finishing, and the whole process can take days instead of hours. The edge banding doesn't take very long and makes the cheap plywood look solid wood, you just gotta be patient cutting it off with a utlity knife. I also use a 3" hole-saw that attaches to a drill and spaced out 8 holes in the long sides and 4 in the short. When you factor in the *hole-cutting + sanding, + laminate + wood conditioner + wood stain and clear, coats* .... it's a. lot of work. The next issue is you need to fasten the fabric to the inside of the frame in order to keep the outside stained wood visible. This requires cutting some thin wood slightly shorter than the outer frame and using it to pinch the fabric up against the inside edges, flush with the outer face of the panel. This was by far the most confusing part for me at first, but when you see a white fabric pop through the holes of a dark wood stained wood on the outside -- it seems worth it. Especially that moment you hang 10 ten of them. They'll be night and day prettier than the bare minimum with slightly better bass absorption because of the holes.
You guys come up with amazing videos. I see that the fabric they use is very elastic, which gives great overall look. For not so elastic materials I would not start from the corners when stapling but rather go from mid to sides and go around the panel frame just as you would tighten screws on your wheels. This is what I was given as an advice from a carpenter and with the panels I made it turned out amazing. Keep up the amazing work, love your videos!!
Our standard fabric is quite stretchy but we also commonly use fabric from Guilford of Maine that has little to no stretch. The same wrapping technique works great for those fabrics as well. There is a tone of ways this can be done, so this is definitely just one option.
No, mineral wool in special textile, special cloth dont missed micro dispersion, it's not going outside box. Most studios have this panels. But if you make like this. Be careful, micro dispersion mineral wool in your lungs, create CANCER in 5 years breathing this.
To be fair I'm not sure much wool would ever be escaping the box. It's not like there will be much air current or disruption in general when indoors that might cause the wool to come out of the box.
I´ve always wondered if the fabric is enough to keep the rockwool particles from the room air or should you wrap the inside material in plastic for example? Especially for bedroom studios where you might sleep and spend a lot of time in. Thanks for a great video!
It depends. If it's a bass trap you're building, plastic is fine as bass freqs will pass through the plastic. However, if it's broadband absorption, the plastic will reflect the high-mid and high freqs, which defeats the purpose of it. What you can do, is use several layers of breathable material (like muslin) as your first and maybe even second layer, before you wrap with the finish fabric. Another great material is Dacron (polyester backing). One or two inches of Dacron will ensure very few fibres escape and it also has the benefit of having great acoustical properties for sound absorption.
Hi Ville, most fabrics work quite well to keep the mineral wool in the panels and not in your room. It also helps that once a panel is made there is nothing to disturb the mineral wool (e.g. cutting, ripping, tearing, etc) so very few if any particles would shed from it, even if it were left uncovered. With that said, it is important not to use any fabric that has a very loose fabric weave. Burlap is an example of a fabric commonly used for panels that does not work well for this. As mentioned above, wrapping panels in plastic would not be advisable in most bedroom applications as it will cause the panels to be reflective in the high frequencies.
Use acoustic cotton batts instead; harmless and equally effective. Rockwool is the new asbestos, not meant to be exposed like that. and only plastic can't contain the tiny particles. Plastic negates the material's absorption properties in the mid and hi frequencies.
@@MusicCityAcoustics No acoustically tranparent fabric can't prevent the particles from coming through it. And they'll shed even when ¨undisturbed¨. Stop using mineral insulation in the fucking open where people can breathe it; use recycled cotton batts instead !
Any advice? .... got a small untreated room, having major issues around 140Hz cause of the low ceiling (about 7 feet high). Gonna get some wall panels and clouds made. Should I make 5cm thick panels with 5cm gaps behind them or make them 10cm and hang against the walls? Also, what's the best density I should get? Note, with the clouds I can also make them 10cm and hang them with a 10cm gap, but the walls are an issue.
probably won’t tell you because rather than using youtube to share knowledge, some people want to make money as much as possible, to the point where they won’t tell you something like this, so you’ll by their product.
Nice and very understanding, is there any specific requirment for the backing fabric? like,airflow or somthing,is it pointless if i use Polypropylene material as backing fabric?
Wouldn't it be loosing fibers/dust with fabric cover only? Some people recommend one layer of pallet strach/film and then putting into frame to wrap with fabric. I'm onto doing my second set of panels and was wandering about that. Thank you for the video.
I might have missed something. Is there a reason why the frames aren't just made to perfectly fit a piece of insulation? That would save a step for every panel.
Anybody else having a hell of time tracking down single packs of rockwool? Any suggestions for best places to order a pack of 8 batts? I'm shooting for 3x48x24.
I get them at Home Creepo in 1.5 inch and double up if needed. I believe brand is Rockwool(formerly Roxul) Comfort board 60 and there is a 2 inch version as well. *Note: not all Home Depots carry this but it can certainly be ordered. Usually $50-60 for a pack of them. 6 or 8 depending on thickness.
What's your stance on using a thin plastic back to wrap the wool? The idea is to make sure the fibers don't get into the air but mainly: If you use a thinner plate but dense material that'll have difficulties dampening lower frequencies but is excellent for higher frequencies, some of the higher frequencies will get reflected by the plastic making for an overall flatter response. Of course at the expense of some performance but I'd rather have weaker dapening on the highs than the room majorly lacking in highs because now the lows can overpower the lacking highs.
If you find you are losing too much the very high end wrapping with the thinnest plastic you can find is great. Think the thickness of a dry cleaning bag; that way it only bounces back the very high end but absorbs most everything else. I have seen people doing this in panel building. In fact in my studio I made frames on my concrete wall to fit these very mineral wool boards and then covered with Burlap fabric and then added VG Douglas fir 3/4" boards with about 4" gaps in between(can be adjusted depending on dampening required) so it looks nice but also reflects back some higher end. On softer woods I use minimal varnish wiped on tight just enough so I can clean the boards and not overcoat the wood and make it sound too harsh. You can hear the difference in sound before and after 3 coats of varnish on a wood floor in a room so I would assume the same applies to wood in studios depending on the density of the wood used.
@@inmemoryofin good question. You know when you walk into a new house and it echos and there is a lot of reverb? but then you move furniture into the room and things dampen up? Kind of like that but maybe more subtle but noticeable. I am talking 100 year old Douglas fir floors, a really soft wood that absorbs quite a bit of sound without a hard as heck protective varnish.
Excellent video! You don't specify the frequency range for the panel you built. All rooms have bass issues. You must start at the low end and solve the problem from 25 Hz to 110 Hz. How thick of a panel like yours would do the trick? Thanks 👍!
Why not make the panels to fit the the mineral wool as purchased, getting rid of the step of cutting them down to size? Is that rigid comfort board 80 by chance?
Great to see a full build of one of these panels. How do you then mount these on a wall? Just a picture wire across the back, hung up on picture hooks, or is there a better way? Cheers
They can be hung with a single French cleat on the back, in addition to the method you described. The downside to this is that a spacer is necessary to include the necessary air gap. I also have a few hung from the ceiling, connected at the top of the panel with two hooks. If hanging, using small turnbuckles between the hooks and rope/chain allows them to be hang straight with a level. Some folks put them on easel stands as an alternative to hanging.
THanks - Can you tell me why some people hang them like pictures with big gaps between and others cover every inch of their wall with accoustic panels?
I have been asked to make some art to 'beautify' panels for restaurant settings. I do paper art. Would adding that to the front of any acoustic absorbing material decrease its effectiveness? The noise absorption they want is for talking from all customers and kitchen type noise. I am open to ideas and instruction - thanks so much.
One of the Best Ideas of SoundProofing is "SoundProof Curtains" That Stops Outside Noise by 80% (25 Db) Tested. Check Here: livesoundproof.com/best-soundproof-curtains/
@@LauraBrown-hg2ry if you want soundproof curtains, get the PVC overlapping strip curtains in the biggest thickness you can handle. You'll drop way more than 25db, but they will be fixed (rather than sliding), you get a decent air seal if you set them up right and it keeps the heat in.
Thank you for the video. Please take notice that thr hardest part was glossed over amd not shown.... the corners. I figured it out eventually but that's kinda shady
Hi Carlito! There are several ways the panels can be installed. We have install guides on our website as well as hardware kits. Check out the install guides here. www.musiccityacoustics.com We also have a video on our website showing how to install them with french cleats. Cheers!
When hanging vertical, Is it better to have the horizontal pieces longer or the vertical pieces longer for structural stability of the frame? In this video he does vertical pieces longer overlapping the horizontal pieces. Is there a reason for this?
I watched it though. Haven't learned all that much new here. Making these panels is a true DIY job -- just get some foam board or mineral wool piece with a a hard backing, and staple some fabric onto it. Putting them in a wood frame makes the result fancier.
Great suggestion! If you want a bunch of mineral wool fibers floating around in your studio that you will enviably end up breathing in. I think the the frame helps contain everything better.
You need an open cell foam, can't use closed cell for sound absorbing panels. And you can't have any hard backing either, that's why you need the wood frame.
Hoping you can help me , can we use non-rigid insulation. Here in NZ we can get fiberglass insulation,but its not in rigid boards. I can stuff it as compact as possible though, would that work?
Hi Chantelle, you can absolutely use nonrigid insulation. For acoustic panels that are 2" to 6" deep, the performance won't be quite as effective but they will still work really well! For really deep bass traps this can actually be beneficial just make sure not to compact it down! Whatever product you end up using, it should be in its original state. Compressing fluffy insulation actually makes its performance worse.
what type of insulation? was trying to figure out thickness of each. I know you mentioned 1x3s, then 3/4 off for backer, leaving 1 3/4". Buy I see 2 layers of insulation and am not familiar with an insulation that' s only 5/8" thick. Great vid though, thank you for the detailed advice!
I’m practically first time building, anything really but, some in my basement right now and realize how much a friggin table comes in handy. My back after finishing one iyiyiyeeeeeee
Hey, just got a question . There are articles about Rockwool that there are risks of getting lung disease and cancer for using it in door... What do you think ?
Hi Emad, with both mineralwool and fiberglass products it is important to protect your lungs and skin when working with the material. In our experience, neither product will shed particles when not disturbed (e.g. cutting, ripping, etc.). Per the manufactures testing, OC Thermafiber is safe to handle in most conditions without protective gear. With that said, we always wrap both the front and back of all of our acoustic panels to ensure they are safe in any setting.
@@MusicCityAcoustics Yes, you wrap it with ACOUSTICALLY TRANSPARENT fabric to let the sound through. Said fabric can't and won't stop the particles from becoming airborne (yes it does that, even a totally undisturbed panel will fill the air of a room with particles; shine a black light anywhere rockwool is used that way, and it looks as if it's snowing). This poison is insulation, meant to be used behind walls and celings, where the particles can't reach your lungs. Fucking new asbestos. USE COTTON acoustic batts INSTEAD ! Same or better results, a little heavier, but harmless to breath.

This is just too cool! I love DIY videos like this! What would be cool is an in-between. I'd love to just purchase the template used in the video to make the frame! Not fully DIY, but not fully constructed, just a time saver ;)
We use OC 6lb. 4lb and 8lb work well too depending on the application, just be careful not to make your panels too thick when using 8lb. The depth of your panels will have a much greater effect on how they work than the density of the material.
I've been building my own panels for years! Good video👍 simple and simple😉 I have optimized it with a perforated wooden plate 3mm thick with hundreds of small holes in between. The diameter of the holes determines the degree of absorption by the panel, the larger the holes, the more broadband is absorbed. Broadband usually means down to about 250h. You can do this if you don't want to process all frequencies so that a part is absorbed and a part is reflected. It can also be rounded off slightly for a slight diffusion so that it is scattered back into the room! 😉 Very simple but effective! It's easy to know that basses cannot be absorbed so too thin! need more material, respectiv thicker panals! this is good for mid to hi absorption !! As shown in the video. About 3.5cm are hi-mid, mid to low 35cm and from 100heart down to 20heart lowend up to 350cm! One would have to insulate This is roughly the formula because a sinus wave up to 12 meters long is generated in the bass wave. depends on the frequency .. Have fun building it yourself! 👍😉
@@seanhayesmusic44 Thermo hemp or mineral wool is both good. With thermal hemp the tightness is better and no harmful substances in it 100% of course up to 90% it consists of hemp barrels and non-flammable! 😉
I checked their website - they have broadband panels that are 4.5" deep, and bass traps at 6.5" deep- but you're absolutely right. Funny story - yesterday one of the dense wool panels I had bought (and hate) fell off the ceiling (they're just attached using 3M stickies right now). I re-measured in that part of the room and found there's a bass issue in that corner at something like 60 hz. What makes it worse is that there's about a 2' chamber between that and a bookshelf that is apparently literally shaking the wall in that one part of the room. I was only using a 1.5" deep high-mid panel there which does nothing for those frequencies for sure!
Does anyone know what kind/brand of backing fabric is recommended? Something to keep the minerals inside the panel while still being acoustically transparent and inexpensive.
Hi, Thank you for the great video. Can I ask what thickness of plywood you are using for the main part of the frame. I know that the bracing piece is 1/2 inch but the thickness of the main elements looks to be bigger what is it? Thank you
Hi Big Zul, the panels come with french cleats for wall mounting. We have a video on our channel showing how to install them. If you'd like a little more info email us through our website and I can send you install guides as well. Cheers!
Hey! It depends on whether they are being installed on a wall, corner, or ceiling and whether they will be flush mounted or with an air gap but for the most part on walls, we use French Cleats. We have a video on our channel showing how to install panels with the included hardware. If you'd like an install guide, I can also email ours. Reach out to us through our website!
I’m making an acoustic insulated dog crate and I want to use a velvet fabric lining. Would it work or is there a specific type of fabric that has the best result?
Hi Jeroen, for a dog crate I think you can use any fabric that is tough enough to withstand the demands of a dog and obviously safe for them to be around. This is outside of our area of expertise so I can't make any specific recommendations.
Hi Allen and thanks! Our standard fabric is FR-DMD Acoustic Fabric. Creating a smooth look can be accomplished with just about any fabric as long it is pulled tightly and straightly during the wrapping process. Avoid, cheaper fabrics though as over time the stitching will loosen and the fabric will start to wrinkle and sag.
The important thing about fabric is that it is transparent to sound. To be sure you can do the following, take the fabric to your mouth and blow, if the air flows freely that fabric is optimal. Flannel or "Jersey" fabrics can work well.
I’m making my own right now for music production! I use wood fibre with 50.2 kg per square meter. Is 45mm enough in thickness? 122cm x 55cm in dimensions
I plan to build some corner bass traps. Commercial corner bass traps are often triangular or round; is it OK to make them Square? Say, 40 by 40 by 120 cm?
This is awesome. No glue = No fumes. I've tried putting my own together and they didn't turn out nearly this well. What really kills me is that these will likely do a much better job than the craptastic panels I got from Amazon for about the same price. I just checked - the broadband panels are way better. I'll be calling (or stopping by if possible) soon I think since they're right here in Nashville. Thanks for this run-thru!
@@Hermiel you actually weren't really wrong. We use 1" 8lb mineral wool in our Low Profile Panels and 2" 6lb mineral wool in the rest of our panels. To get the extra depth for Broadband and Bass Trap panels we stack 2" pieces.
Would there be any downside using wood glue on the parts you used the nail gun on? I make more of a triple triangle but with the mounting and spacing from apart it looks like artsy rectangle with a little wall showing through. I’ve found no difference between using full rectangles vs the triangular rectangle. Only product I found to work better are the thick blankets
Wood glue works great! and no toxic fumes. Sometimes finish nails can back out, but usually don't since the fabric is holding them. I use small headed deck screws predrilled or countersink screws. Turns out wood glue is just as strong on end grain as face grain joints (as strong as the wood). I always thought the opposite.
If anyone has ever taught you how to make a bed properly, the folds are essentially the same as when you tuck your flat sheet under the end of your mattress. Or, like gift-wrapping the ends on a square box.

Amazing video! Especially love your tempalte table. However.... I am to improve the nursery for my son and i wanted to hang a few panels in there to improve the reverb. As many people are mentioning there could potentially be some health issues with wrapping mineral wool in nothing but a thin peace of cloth.? Also giving this is for my son, the panels are tp be hung fairly low in order to catch the direct reflections of his mouth and toys and therefore it is to be expected that these panels will be hit, tapped, get in contact with toys or in other way be handled a tad rough. In general theres 2 questions. - Is it safe with mineral wool or other insulation alike, or what other material would you recommend (considering the panels will not be left in peace) - How/What can you do to improve the sustainability of the panel with minimal cost of effect?
Hi there, may I ask how thick is the insulation material and does it matter how thick it is. It seems like you stacked 2 x 2" together, so just wanna clarify on that :)
wouldn’t it be better to have the frame flipped the other way and put the backing fabric in first, so it’s not covering the limber at the back. this way you can also use a support bar as a french cleat.
So the blue fabric is the only thing holding the sound insulation in place? Are there any issues with the insulation sagging over time or stretching the blue fabric making it bulge?
rockwool is rather firm from its density. Properly applied fabric holds up well, preventing sag. Had some for almost 10 years, no sag. Mine were made the same way pretty much.
The 6.5" panels I have from them that are being used in my cloud do bulge slightly. They've been hanging face down for maybe 7 months now. The sag's not bad, it just looks a little puffier than the same ones hanging vertically in the corners, which don't seem to be bulging at all. In bright light you can see a slight change of color between the frame and covered insulation, I assume that's from the blue backing material behind the white GOM outer fabric I have on my panels. I haven't noticed any fibers AT ALL in the room, on my hands, or on my clothes, and I handled these panels quite a lot before installing them.
I'm not sure what they used, but a general rule of thumb is: the thicker your insulation the lower the frequencies will be that it can absorb, denser insulation also does a better job to a certain extent, at some point it will start reflecting high frequencies though. What I've seen and read online so far people tend to use insulation that weighs about 40-45kg/m3 (sorry if you're using imperial units idk those)
@@danoontjeh123 Thanks, that's useful. A construction store nearby has 5cm thick and 60kg/m3 for sale. Now my next worry is whether it's carcinogenic or not (different articles say different things...)
Hi Rob, we have a few panels in there but yes you're right, we could probably use a few more. Check out the other video we did with Adam Audio and you'll see where it all goes! Cheers!
Acoustic panels are very expensive, but when you see all the specifications they have to meet and I'd imagine even certifications, then you realise there is more to the cost than just labor and materials. Also, for architectural purposes, a certain level of quality and service is expected. For home though, I'd just make them myself
@@tommasobuzza1943 How do you know it's toxic? Could you pleace send a link to read about? I asked them(rockwool)on their website but they did't replied
@@hiiishrhl6553 from what I have read, at the very least mineral wool can be expelled by the lungs versus fiberglass. I would say a global Canadian mineral wool company would not put something that is seriously dangerous in their mineral wool. Maybe glues that hold the fiber into shape but still probably less toxic than walking in the average city that has cars? and I would say after some time any chemicals off gas. Similar to most varnishes etc which become food safe after curing.
If the rock wool I’m using is 3” thick, what should be the exact width of the wood? I originally thought the rock wool I ordered was 4” thick, so I cut the wood 5”. Is that too much space? If so, should I add an extra inch of rock wool in the frame?
Performance is improved when there is air space behind the panels. It is often recommended to just hang the panels from the wall no more than 1/2 the depth of the insulation. Air is cheaper than Rockwool, I would just put the 4” bats in the frame you have.

Wouldn't it be simpler to make the frame slightly larger so the insulation would not have to be cut at all?
Hi RJB, on a small scale yes it would be. However, when making panels on a larger scale there are a couple of reasons making the frames larger is not the best option. 1. When building the frames, we would have a ton of wood waste. With the dimensions of our frames, we have almost zero wood waste.

No, mineral wool in special textile, special cloth dont missed micro dispersion, it's not going outside box. Most studios have this panels. But if you make like this. Be careful, micro dispersion mineral wool in your lungs, create CANCER in 5 years breathing this.
Cellulose Fibre manufactured from recycled newspapers and also sheepswool is good natural options.
To be fair I'm not sure much wool would ever be escaping the box. It's not like there will be much air current or disruption in general when indoors that might cause the wool to come out of the box.
The template is the game changer.
Great video, thank you! Just a quick question: is Recycled Denim a good/equal option?
Thank you
I make the frame 3 inches thick and put a Sonopan panel at the back for to treat another level of frequencies. It works really well.
I´ve always wondered if the fabric is enough to keep the rockwool particles from the room air or should you wrap the inside material in plastic for example? Especially for bedroom studios where you might sleep and spend a lot of time in. Thanks for a great video!
It depends. If it's a bass trap you're building, plastic is fine as bass freqs will pass through the plastic. However, if it's broadband absorption, the plastic will reflect the high-mid and high freqs, which defeats the purpose of it.
What you can do, is use several layers of breathable material (like muslin) as your first and maybe even second layer, before you wrap with the finish fabric. Another great material is Dacron (polyester backing). One or two inches of Dacron will ensure very few fibres escape and it also has the benefit of having great acoustical properties for sound absorption.
Hi Ville, most fabrics work quite well to keep the mineral wool in the panels and not in your room. It also helps that once a panel is made there is nothing to disturb the mineral wool (e.g. cutting, ripping, tearing, etc) so very few if any particles would shed from it, even if it were left uncovered. With that said, it is important not to use any fabric that has a very loose fabric weave. Burlap is an example of a fabric commonly used for panels that does not work well for this.
As mentioned above, wrapping panels in plastic would not be advisable in most bedroom applications as it will cause the panels to be reflective in the high frequencies.
Use acoustic cotton batts instead; harmless and equally effective. Rockwool is the new asbestos, not meant to be exposed like that. and only plastic can't contain the tiny particles. Plastic negates the material's absorption properties in the mid and hi frequencies.
@@MusicCityAcoustics No acoustically tranparent fabric can't prevent the particles from coming through it. And they'll shed even when ¨undisturbed¨. Stop using mineral insulation in the fucking open where people can breathe it; use recycled cotton batts instead !
spraying the mineral-wool slabs with a diluted PVA glue helps to keep fibre shedding down
Which insulation is better? Mineral wool or fiberglass? Thank you.
What gauge and length of brad nails are you using?
Whats that white fabric called?
Any advice? .... got a small untreated room, having major issues around 140Hz cause of the low ceiling (about 7 feet high). Gonna get some wall panels and clouds made. Should I make 5cm thick panels with 5cm gaps behind them or make them 10cm and hang against the walls? Also, what's the best density I should get? Note, with the clouds I can also make them 10cm and hang them with a 10cm gap, but the walls are an issue.
What fabric did you use? Are some better than others at maintaining the fibres from escaping?
Would like to know too
Looks like poly poplin. You can install a thin layer of dacron in front of fiberglass or mineral wool insulation if you want to be safe
Guilford of Maine is what most companies use. Expensive but doesn't stretch and droop over time. Duckcloth is also popular and roughly half the price
probably won’t tell you because rather than using youtube to share knowledge, some people want to make money as much as possible, to the point where they won’t tell you something like this, so you’ll by their product.
There is just something about a woodwork studio. Great job!
Nice and very understanding,
is there any specific requirment for the backing fabric? like,airflow or somthing,is it pointless if i use Polypropylene material as backing fabric?

Wouldn't it be loosing fibers/dust with fabric cover only? Some people recommend one layer of pallet strach/film and then putting into frame to wrap with fabric. I'm onto doing my second set of panels and was wandering about that. Thank you for the video.

great job ! but how do you hang it and let a space with the wall ? french cleat ?
Nice video. Concise and to the point. Great work.
Thank you for watching! Glad you liked it.
What insulation material is that?
I might have missed something. Is there a reason why the frames aren't just made to perfectly fit a piece of insulation? That would save a step for every panel.
Probably so they can minimize lumber waste? That's all I can think of...
@romancecoffeeroaster That's actually a pretty valid reason, thanks.
Anybody else having a hell of time tracking down single packs of rockwool? Any suggestions for best places to order a pack of 8 batts? I'm shooting for 3x48x24.
I get them at Home Creepo in 1.5 inch and double up if needed. I believe brand is Rockwool(formerly Roxul) Comfort board 60 and there is a 2 inch version as well. *Note: not all Home Depots carry this but it can certainly be ordered. Usually $50-60 for a pack of them. 6 or 8 depending on thickness.
What's your stance on using a thin plastic back to wrap the wool? The idea is to make sure the fibers don't get into the air but mainly: If you use a thinner plate but dense material that'll have difficulties dampening lower frequencies but is excellent for higher frequencies, some of the higher frequencies will get reflected by the plastic making for an overall flatter response. Of course at the expense of some performance but I'd rather have weaker dapening on the highs than the room majorly lacking in highs because now the lows can overpower the lacking highs.
If you find you are losing too much the very high end wrapping with the thinnest plastic you can find is great. Think the thickness of a dry cleaning bag; that way it only bounces back the very high end but absorbs most everything else. I have seen people doing this in panel building. In fact in my studio I made frames on my concrete wall to fit these very mineral wool boards and then covered with Burlap fabric and then added VG Douglas fir 3/4" boards with about 4" gaps in between(can be adjusted depending on dampening required) so it looks nice but also reflects back some higher end. On softer woods I use minimal varnish wiped on tight just enough so I can clean the boards and not overcoat the wood and make it sound too harsh. You can hear the difference in sound before and after 3 coats of varnish on a wood floor in a room so I would assume the same applies to wood in studios depending on the density of the wood used.
@@jonwikan3986 How would you describe the sound difference between pre and post varnish?
@@inmemoryofin good question. You know when you walk into a new house and it echos and there is a lot of reverb? but then you move furniture into the room and things dampen up? Kind of like that but maybe more subtle but noticeable. I am talking 100 year old Douglas fir floors, a really soft wood that absorbs quite a bit of sound without a hard as heck protective varnish.
Cellulose Fibre manufactured from recycled newspapers and also sheepswool is good natural options.
I was thinking the same thing. Also figure out an optimum size to cut the fabric so it doesn't require additional trimming as well
Excellent video! You don't specify the frequency range for the panel you built. All rooms have bass issues. You must start at the low end and solve the problem from 25 Hz to 110 Hz. How thick of a panel like yours would do the trick? Thanks 👍!
insulation made of?
where to buy it or how to made that?
Do you use two different densities of rockwool ?
In a commercial room, roughly 30 by 50 feet square, and a 10 feet ceiling, would these work as well? And how far apart would we hang them?
Why not make the panels to fit the the mineral wool as purchased, getting rid of the step of cutting them down to size? Is that rigid comfort board 80 by chance?
Great to see a full build of one of these panels. How do you then mount these on a wall? Just a picture wire across the back, hung up on picture hooks, or is there a better way? Cheers
They can be hung with a single French cleat on the back, in addition to the method you described. The downside to this is that a spacer is necessary to include the necessary air gap. I also have a few hung from the ceiling, connected at the top of the panel with two hooks. If hanging, using small turnbuckles between the hooks and rope/chain allows them to be hang straight with a level. Some folks put them on easel stands as an alternative to hanging.
@@inmemoryofin that's very useful. Thanks!
THanks - Can you tell me why some people hang them like pictures with big gaps between and others cover every inch of their wall with accoustic panels?
I have been asked to make some art to 'beautify' panels for restaurant settings. I do paper art. Would adding that to the front of any acoustic absorbing material decrease its effectiveness? The noise absorption they want is for talking from all customers and kitchen type noise. I am open to ideas and instruction - thanks so much.
Most likely yes. If you can find a breathable fabric like some light cotton and draw on there, that would be your best bet.
Thats why i love @adamaudio

I bought some borgaline fabric, it's some form of cotton? Would this be suitable to cover the panels with?
Thank you for the video. Please take notice that thr hardest part was glossed over amd not shown.... the corners. I figured it out eventually but that's kinda shady

what stops the itchy material from passing through the fabric?
Great video, thank you.
What density rockwool do you use? My local supplier in South Africa has 60, 80, 100, 120 and 160kg/m3 available.
Thank you!
I think approximate 45-60 kg/m³, but for bass traps or small room you need over 100 kg/m³. To catch low frequencies.
Not too much, it will be like solid wall, and mirroring sound.
Wish you would have showed us more detain on folding the corners
How do you intall them w/o fasteners showing?
So how do you hook it up onto the wall, is there a extra piece that hangs it up onto the wall or do you just use the two sided duck tape ?

When hanging vertical, Is it better to have the horizontal pieces longer or the vertical pieces longer for structural stability of the frame? In this video he does vertical pieces longer overlapping the horizontal pieces. Is there a reason for this?
I watched it though. Haven't learned all that much new here. Making these panels is a true DIY job -- just get some foam board or mineral wool piece with a a hard backing, and staple some fabric onto it. Putting them in a wood frame makes the result fancier.
Great suggestion! If you want a bunch of mineral wool fibers floating around in your studio that you will enviably end up breathing in. I think the the frame helps contain everything better.
You need an open cell foam, can't use closed cell for sound absorbing panels.
And you can't have any hard backing either, that's why you need the wood frame.
How thick is the rockwool you use?
Hoping you can help me , can we use non-rigid insulation. Here in NZ we can get fiberglass insulation,but its not in rigid boards. I can stuff it as compact as possible though, would that work?
Hi Chantelle, you can absolutely use nonrigid insulation. For acoustic panels that are 2" to 6" deep, the performance won't be quite as effective but they will still work really well! For really deep bass traps this can actually be beneficial just make sure not to compact it down! Whatever product you end up using, it should be in its original state. Compressing fluffy insulation actually makes its performance worse.
@@MusicCityAcoustics thank you so much for the reply! So helpful

Hey, just got a question .
There are articles about Rockwool that there are risks of getting lung disease and cancer for using it in door... What do you think ?
Hi Emad, with both mineralwool and fiberglass products it is important to protect your lungs and skin when working with the material. In our experience, neither product will shed particles when not disturbed (e.g. cutting, ripping, etc.). Per the manufactures testing, OC Thermafiber is safe to handle in most conditions without protective gear. With that said, we always wrap both the front and back of all of our acoustic panels to ensure they are safe in any setting.
@@MusicCityAcoustics Yes, you wrap it with ACOUSTICALLY TRANSPARENT fabric to let the sound through. Said fabric can't and won't stop the particles from becoming airborne (yes it does that, even a totally undisturbed panel will fill the air of a room with particles; shine a black light anywhere rockwool is used that way, and it looks as if it's snowing). This poison is insulation, meant to be used behind walls and celings, where the particles can't reach your lungs. Fucking new asbestos. USE COTTON acoustic batts INSTEAD ! Same or better results, a little heavier, but harmless to breath.

This is just too cool! I love DIY videos like this! What would be cool is an in-between. I'd love to just purchase the template used in the video to make the frame! Not fully DIY, but not fully constructed, just a time saver ;)
Hello Can you tell me the specs of the mineral wool used? Here in Brazil there are several densities to choose. And prices varies a lot
I used Roxul “Safe N Sound” on my studio panels. Works great!
We use OC 6lb. 4lb and 8lb work well too depending on the application, just be careful not to make your panels too thick when using 8lb. The depth of your panels will have a much greater effect on how they work than the density of the material.
whats the density of the rock wool? 40kg/m3 or 80 or 100?
Hi there, we have a disagreement here; is all the frame made of plywood or only the center piece?
Looks like it.
I've been building my own panels for years!
Good video👍
simple and simple😉
I have optimized it with a perforated wooden plate 3mm thick with hundreds of small holes in between. The diameter of the holes determines the degree of absorption by the panel, the larger the holes, the more broadband is absorbed. Broadband usually means down to about 250h.
You can do this if you don't want to process all frequencies so that a part is absorbed and a part is reflected. It can also be rounded off slightly for a slight diffusion so that it is scattered back into the room! 😉 Very simple but effective!
It's easy to know that basses cannot be absorbed so too thin! need more material, respectiv thicker panals! this is good for mid to hi absorption !! As shown in the video. About 3.5cm are hi-mid, mid to low 35cm and from 100heart down to 20heart lowend up to 350cm! One would have to insulate
This is roughly the formula because a sinus wave up to 12 meters long is generated in the bass wave. depends on the frequency ..
Have fun building it yourself! 👍😉
Thank you so much for sharing your knowledge! :)
What insulation do you use?
@@seanhayesmusic44 Thermo hemp or mineral wool is both good. With thermal hemp the tightness is better and no harmful substances in it 100% of course up to 90% it consists of hemp barrels and non-flammable! 😉
I checked their website - they have broadband panels that are 4.5" deep, and bass traps at 6.5" deep- but you're absolutely right.
Funny story - yesterday one of the dense wool panels I had bought (and hate) fell off the ceiling (they're just attached using 3M stickies right now). I re-measured in that part of the room and found there's a bass issue in that corner at something like 60 hz. What makes it worse is that there's about a 2' chamber between that and a bookshelf that is apparently literally shaking the wall in that one part of the room. I was only using a 1.5" deep high-mid panel there which does nothing for those frequencies for sure!
@@mosermichael4404 where do you get thermo hemp?
what is the type of mineral wool they use? or brand?
Does anyone know what kind/brand of backing fabric is recommended? Something to keep the minerals inside the panel while still being acoustically transparent and inexpensive.

I’m making an acoustic insulated dog crate and I want to use a velvet fabric lining. Would it work or is there a specific type of fabric that has the best result?
Hi Jeroen, for a dog crate I think you can use any fabric that is tough enough to withstand the demands of a dog and obviously safe for them to be around. This is outside of our area of expertise so I can't make any specific recommendations.
If it works for a dog it should work for a parrot too right?
Great video. What kind of fabrics do you use for front panel? I really like the smooth and winkel free like you guys use.
Hi Allen and thanks! Our standard fabric is FR-DMD Acoustic Fabric. Creating a smooth look can be accomplished with just about any fabric as long it is pulled tightly and straightly during the wrapping process. Avoid, cheaper fabrics though as over time the stitching will loosen and the fabric will start to wrinkle and sag.
The important thing about fabric is that it is transparent to sound. To be sure you can do the following, take the fabric to your mouth and blow, if the air flows freely that fabric is optimal. Flannel or "Jersey" fabrics can work well.

Wood glue works great! and no toxic fumes. Sometimes finish nails can back out, but usually don't since the fabric is holding them. I use small headed deck screws predrilled or countersink screws. Turns out wood glue is just as strong on end grain as face grain joints (as strong as the wood). I always thought the opposite.

Amazing video! Especially love your tempalte table.
However....
I am to improve the nursery for my son and i wanted to hang a few panels in there to improve the reverb. As many people are mentioning there could potentially be some health issues with wrapping mineral wool in nothing but a thin peace of cloth.?
Also giving this is for my son, the panels are tp be hung fairly low in order to catch the direct reflections of his mouth and toys and therefore it is to be expected that these panels will be hit, tapped, get in contact with toys or in other way be handled a tad rough.
In general theres 2 questions.
- Is it safe with mineral wool or other insulation alike, or what other material would you recommend (considering the panels will not be left in peace)
- How/What can you do to improve the sustainability of the panel with minimal cost of effect?
No mineral wool should be used in nursery, especial with possibility of contact.
is it better to risk irritation from the insulation or gloves getting tangled in the blade?
I want to know why the frame wasn't just made a bit bigger so you don't have to cut the insulation?
Do you have any ideas to make the back side look more neat..
Use a fitted sheet to cover the backside, but it'll be hung on that side so who cares what it looks like?
I usually staple the front fabric first and then staple the backing fabric on the back, cutting the excess with an exacto knife
Hi there, may I ask how thick is the insulation material and does it matter how thick it is. It seems like you stacked 2 x 2" together, so just wanna clarify on that :)
I see he noted that is actually 1 inch rockwool, they were out of 2 inch that day.
wouldn’t it be better to have the frame flipped the other way and put the backing fabric in first, so it’s not covering the limber at the back. this way you can also use a support bar as a french cleat.
This is an excellent guide. So glad I found this video before building my own panels.
So the blue fabric is the only thing holding the sound insulation in place?
Are there any issues with the insulation sagging over time or stretching the blue fabric making it bulge?
rockwool is rather firm from its density. Properly applied fabric holds up well, preventing sag. Had some for almost 10 years, no sag. Mine were made the same way pretty much.
The 6.5" panels I have from them that are being used in my cloud do bulge slightly. They've been hanging face down for maybe 7 months now. The sag's not bad, it just looks a little puffier than the same ones hanging vertically in the corners, which don't seem to be bulging at all. In bright light you can see a slight change of color between the frame and covered insulation, I assume that's from the blue backing material behind the white GOM outer fabric I have on my panels. I haven't noticed any fibers AT ALL in the room, on my hands, or on my clothes, and I handled these panels quite a lot before installing them.
Whats the thickness and density of the rock wool? I'm DIY-ing this but not sure which type of rock wool to get.
I'm not sure what they used, but a general rule of thumb is: the thicker your insulation the lower the frequencies will be that it can absorb, denser insulation also does a better job to a certain extent, at some point it will start reflecting high frequencies though. What I've seen and read online so far people tend to use insulation that weighs about 40-45kg/m3 (sorry if you're using imperial units idk those)
@@danoontjeh123 Thanks, that's useful. A construction store nearby has 5cm thick and 60kg/m3 for sale. Now my next worry is whether it's carcinogenic or not (different articles say different things...)
Is that comfortboard you’re using? If so is it 40, 60 or 80?

Hi Rob, we have a few panels in there but yes you're right, we could probably use a few more. Check out the other video we did with Adam Audio and you'll see where it all goes! Cheers!
I guess, but it's a woodworking shop, not a recording studio...
why did you choose plywood strips instead of cheap dimensional lumber, like 1x4s?
Acoustic panels are very expensive, but when you see all the specifications they have to meet and I'd imagine even certifications, then you realise there is more to the cost than just labor and materials.
Also, for architectural purposes, a certain level of quality and service is expected.
For home though, I'd just make them myself

If the rock wool I’m using is 3” thick, what should be the exact width of the wood? I originally thought the rock wool I ordered was 4” thick, so I cut the wood 5”. Is that too much space? If so, should I add an extra inch of rock wool in the frame?
Performance is improved when there is air space behind the panels. It is often recommended to just hang the panels from the wall no more than 1/2 the depth of the insulation. Air is cheaper than Rockwool, I would just put the 4” bats in the frame you have.
