DIY Acoustic Panels
Вставка
- Опубліковано 7 сер 2024
- I made these DIY acoustic panels (also known as an acoustic cloud) for my garage workshop to help improve the audio quality of my videos. I made 6 panels and they've made a huge difference to reduce the amount of reverberation due to all of the sound waves that were reflecting off all of the hard surfaces in my garage. I might even make a few more.
These would be great in a media room, as well, although you might want to use a better quality fabric, or change the design a little. The acoustic panels that I made are just "garage quality" so I would definitely change the design if they were to be placed inside the house.
I use a Kreg K4 pocket hole jig for the assembly of the frame. This is something I recently won in a contest from Instructables.com. Thank you, Instructables! It has turned out to be a big time saver. I was able to build and install all of these panels in an afternoon.
Here are Amazon links to some of the things I used to make these acoustic panels:

love your tools man. they are great
Those Kreg tools are priceless
Brilliant intro!!!
I am about to do the same. I am glad to see that what I had in mind, really exist! TKS a lot. BTW I have the same ring in litle finger.

If you leave a maximum of air space in the sides of the frame, e.g. connecting two thin frames along the corners, the panel has twice the efficiency.
Great project, I am moving right now and my Ham Radio studio and workshop space has absolutely terrible acoustics! I really think this will help!
Seems like towels will do a better job, much faster, much easier, and pretty enough to hang inside.
I covered my broadband absorbers in a thin plastic film (the stuff used for food), then two layers of cloth outside, this is to prevent any dust entering the room. The two pieces of cloth will stop fibers from escaping and it will also dampen the very high frequency that the plastic might reflect.
It is not an issue, unless you handle the material. Whether the fabric will reflect *high frequencies i.e. treble* (not absorb) depends whether you can breathe through it (treble has directional dispersion). Just make sure to avoid insulation with harmful binding material like formaldehyde.
I realise you posted this two years ago. But, combined with what I have learned to save myself money sorting out my studio, plus this, I am diving in to make my own panels. Thank you for the straightforward explanation. Also, thanks for the amazon links. Luckily Amazon UK sells them too :).
I would make it! I think I would come up with a variation to block some urban noise coming in towards the bedrooms. It might work, so I'll add it to my list of experiments. Thanks!

My fear would be dust and fiber finding its way through the burlap with vibrations and loud noises. Try hanging a white paper beneath damper, knock the damper and check for fall through!
can other acoustic fabrics for the looks could be added over the burlap
Yes, I Wood Make It! But, I don't do it - U DO IT!!! hahahaha! Thanks for the video. I bought a bunch of roxul for my sons studio and I have the fabric. I gotta get on these right away - he is tired of hearing reflections in his music studio.

A fine mist coat of diluted PVA can be used to bond potentially stray fibres to a rockwool slab, without closing up any pores in the material. Incidentally, an even cheaper option to burlap is plastic weed control fabric (for those not worried about the appearance, on a tight budget).
Thank you so very much for your great video, mate. So helpful and much appreciated.
what would you say is the highest quality fabric for the panels. you mentioned how you settled for burlap
Using a porous fabric such as speaker cloth surely won't prevent the fibres from the rockwool escaping over time?
You´re good as long as you´re not having a WWE session with them.
I think you can order the Roxul in 24 inch width too
how many inches of burlap did you use to make 4 panels?
Great job. Could I get the name of that blue drill guide that's used at 2:00?
That's called a pocket hole jig. There are different versions, but the one that I used is the Kreg K4. You can find it on Amazon here: amzn.to/2FJWrbP
I love it
👌🏼 agree about the fibre though, but something else can be used
Rock Wool
great video! if the Rockwool I have is 15 1/4 wide, should I make the Frame 15 inches wide? or 14.5? not sure about that. thanks for any advice
I don't think it would matter. Whatever one is easier for you.
I’m glad it worked for your audio. Did it make a difference in the overall sound reduction in the shop?
They may absorb a small amount of the sound waves, but it's a fairly negligible amount. Another thing that I did after making these was to install rubber anti-fatigue mats on the floor. Not only do they make the shop much more comfortable, but they also help to dampen the reflection of the sound waves. The big reduction in the reverberation definitely makes the shop seem quieter.
Dude put an amazon affiliate link in your description for all the tools and supplies you use. Make it easy for us to buy stuff needed and you make a few bucks too.
Thanks for the suggestion. I've been adding links in my more recent videos, but somehow this one was neglected. I've added in a few Amazon links that I hope will be helpful.
could you place the pocket hole screws on the inside of the corners?
It's possible to do that, but then the screws will be piercing the adjoining pieces very close to their ends, which could cause the wood to split. That's why I did it from the outside.
my ceiling has this rockwool behind the ceiling panel so i would build them gor the walls but how many? and were
the new room is 6 mtr x 10 mtr ,and to be used just for guitar rehersal; no issues with neighbours, just to add a bit of deadening and reduction of uneanted reverb what do you suggest ?
Hi Stephen, I'm definitely not an expert in this area, but here are a few thoughts. You mentioned that you have Rockwool behind the ceiling panel. This will help deaden the sound transmission, but it will not help to eliminate the reverb. For this reason, you "might" want to consider hanging a couple of panels from the ceiling to help reduce the reflection of sound waves off the ceiling. It's hard to estimate how many panels to put on the walls. You have a pretty large room, so I would suggest putting 3 or 4 on each of the 10m walls, and maybe a couple on each of the 6m walls. Anything would be better than nothing, and you can also add more at a later time, if needed. If there are others out there with more expertise, feel free to chime in! --Mike
Wood U Make It i am just having this room built with a concrete floor, and a 2.7 high ceiling; the reason for the rockwool in the ceiling is to reduce the heat, i live in area thats allways 30 deg. This room is to be used as a rehersal room Amplifiers Drums etc.t
There is no reason to sound proof it, as that is not an issue no neighbours itj ust to eliminate the hollowness, the unwanted echo, the ring, the emptyness. as fully sound proofing would be to dead. so will home made rockwool panels positioned along the 10 mtr walls give me the result kind regards Stephen
I've seen a number of comments regarding concerns with the safety of using insulation behind breathable fabric. I made similar panels for my studio using Roxul Safe n Sound and now have some concerns. I've read sources saying the material is safe. Wondering if you have dug a little deeper on this.
According to the Rockwool safety data sheets that I've found online, it is not classified as being dangerous to health. Since my panels are left relatively undisturbed, I think there is very little likelihood that any fibers are actually being emitted into the air. I'm more concerned about sawdust from all my tools than I am about the Rockwool fibers.
@@quantum_ocean youre crazy
@@Woodumakeit Yes Rockwool fibers fall to the ground. They are heavier than fiberglass.
Will putting these on your ceiling soundproof in a way so your upstairs neighbors cannot hear you as much? Or do they just enhance the sound in the room
They help primarily with the reflection of sound waves, but won't really do anything for soundproofing. A way to soundproof the ceiling would be to add another layer of drywall that has been decoupled from the current drywall layer. That's a lot of work though!
And do it with quiet rock too for the best sound proofing, but now add expensive to the lot of work part.
Soundproofing a room/studio is TOTALLY different to sound treating a room/studio. Soundproofing stops sound getting in or out of a room/studio. Sound treating is using sound absorbent panels or tiles to take echo/reverb out of a room/studio you want to record in. Most important thing in sound treating is having bass traps as they absorb all frequencies whereas tiles or panels will only absorb high and mid frequencies... it's a very complex business!
is it important to place the panel separately from the wall?
I think they'd work fine attached to the wall, but if they're set a distance off the wall (or hanging from the ceiling) they will be able to absorb some of the reflected sound waves.
I'm looking to build some of these for my home theater and studio. your video is awesome and easy to follow, but my question are, isn't it bad to breath in that insulation? How do you keep the fibers from floating around your will space?
It's probably a good idea to wear a dust mask when cutting and handling the insulation. Apart from that, I don't think it's a big threat because the panels are wrapped with fabric. The batts of insulation are not being disturbed while hanging from the ceiling, so I don't think there will be many fibers floating around OASH has a standard for daily exposure in the workplace. I have no way of measuring where I stand in my workshop, but I think I have a relatively low exposure to the mineral wool fibers.
Wood U Make It thanks for the speedy reply. I will be making some of these soon. I will be using on the ceiling and walls. I'll let you know how the finished product comes out.
Good luck with your build. I'm definitely interested to hear/see how it turns out!
My 2 cents:
Roxul is made from ground up rocks !!
No fibers, no chemicals…
While I agree that common sense says wear a dust mask, you absolutely don’t have to.
Cheers
Sound absorption is usually defined in terms of the absorption coefficient (usually represented by the Greek letters α) and is defined as the ratio of the absorption to the incident sound energy from a single interaction between the acoustic wave and a certain material.

what's the name of the song?
Nice!
Question, you spent the extra time making angular holes to make the frame look good, and yet, the covering wasn't completely wrapped for a stunning finish?
Well, they were only for my workshop and hanging up high, so it wasn't too important for this application. I definitely would wrap them much better if the circumstances dictated.
@@Woodumakeit great work still.
I'll be using this method with some slight changes.
Thanks for sharing :-)
wish he showed the final install of all the panels!

what did you call that sound transparent material? burlab? could you spell it? I need something like that but more water resistant or proof as I am fitting rockwool (the denser rockwool) inside a fence between both sides for outdoor use.
It's called burlap. It's definitely not water proof or even water resistant. I'm not sure what a good material would be for outdoor use.
Very nice! The difference between the two choices of insulation, on a scale from 1 to 10, being used for your application, is about a +0.1. I heard a tremendous difference from the start of your video, till the end. I use JBL 8 inch Mons in a very treated control room and your video sounded great! What Lav mic are you using? You got the job done, great job!
Thanks for your comment! I use a relatively inexpensive lav mic that I bought from Amazon: amzn.to/2ATi4E2 I kind of regret not getting a wireless mic because I spend a lot of time untangling the cord. I recently got the Zoom H6 recorder and I used that for my latest video (ua-cam.com/video/KzJRdkgeABQ/v-deo.html ) with my lav mic plugged into it. It's made a world of difference!
I use the H6 myself, it is a great piece of hardware. I live very close to Dulles International Airport so wireless systems or not an option for me. I will check out your last video with the H6. (Your Video Link Is Dead). As far as Lav mics go, I use 4 to 8 AT Pro 70s, depending on how the recording is going. They work great for interviews or miking up instruments like violins, fiddels or cellos.
You're close by! I live in Burke. Sorry about the broken link. It mistakenly included the right parenthesis in the url. Here it is again: ua-cam.com/video/KzJRdkgeABQ/v-deo.html
I live in Manassas. I also have a studio in Northern Neck Va. Your audio on the Urn sounds FANTASTIC!
Thanks!

You’re not worried about going into joists (studs) on the ceiling?
I’m only asking, I’m not a contractor.
But it doesn’t seem like that would be very secure for something hanging over my head. Thoughts?
Those panels are pretty light, so I'm not worried that the drywall plugs wouldn't be able to support the weight.
@@Woodumakeit
Very cool !
I enjoyed your presentation and I’m jealous you have all of those awesome tools !!!
I used an easier to handle version of the mineral wool, called Roxul ComfortBoard, that is compressed into rigid panels. It has superb sound absorbency and is only 1.5" thick. It is available at HomeDepot for less than $50 for 6x sheets 2' x 4' each. I put a few 1" angle brackets inside the wood frame to hold the board into the frame so that the fabric doesn't need to carry the weight of the material. For more info look at: www.rockwool.com/products/comfortboard-80 or a full data sheet at:
cdn01.rockwool.com/siteassets/o2-rockwool/documentation/technical-data-sheets/residential/COMFORTBOARD-80-Non-Structural-Sheathing-Continuous-Insulation-Techdata.pdf?f=20180618131832
Roxul ComfortBoard is a better Choice....
does the joint you used have a name?
It's just a simple butt joint that I used along with pocket holes and screws to hold everything together. I guess you could also call it a pocket-hole joint.
Why do you need the glue between the joints?
It's definitely not necessary. I just like to build things extra strong.
Can it cut outside noise ?
No, they only help reflected noise from within the room. You´ll have to build a ´room within a room´ by decoupling walls acoustically.
You will find discussions in a studio forum, like gearslutz.com.
I´ve also seen construction products from: dreamscreen.no/collections/construction-products (Norway)
at one point over 20 years ago, I stapled hundreds of egg-cartons to four walls and a ceiling, creating a decent environment for jamming ... but hopeless for recording (plaster walls and pine studs vibrate in the damndest ways). Cheers. $0.02

great video what materials did you used?
I used pine for the sides and stone wool insulation (I bought Roxul ComfortBatt by mistake, but I should have used Roxul Safe'n'Sound for better sound absorption). Then I covered everything with burlap fabric.
a lot of thanks BIG LIKE!
Rockwool RWA45 what you think this is good or just roxul?
I think the Rockwool RWA45 would be fine. It has a slightly higher density than the Roxul (45kg/m3 vs 40), but it is sold as acoustic insulation, so I think it would work well.
Why do 5 panels verses 1 giant panel that covers the entire wall or ceiling
It would sag. Though maybe you could tighten some wires across to hold it up. Probably need a lot of tension.
what kind of wood is that. i am searching to
I just used pine for these panels. Not too expensive, and plenty strong for this application.
whats the name of wood..
rookwool it s good?
where can I get acoustic panel in Nigeria
I don't know enough about suppliers in Nigeria to help you. I suggest trying Google and seeing what you can find.
See if you can find any of these. The calculator at the bottom will show you the efficiency depending on material and thickness.

Suggestion, use layers of old towels for filling instead.
@@blazsrsa2246 Suprisingly layers of towel material can be even more effective than expensive audio foam.

This is amazing! Any chance you know how much each panel weighed when you were done? Thinking about doing something like this to hang on the wall in my wife's violin studio.
I recently moved to a new workshop and haven't hung them up yet, so that made it easy to weigh them. Each one is 4.5 kg or just slightly less than 10 lbs.
@@Woodumakeit Thanks!

is it dangerous using rockwool materials?
I'd recommend wearing a dust mask when cutting and handling the insulation. Apart from that, I don't think it's any more dangerous than breathing in sawdust. The panels are wrapped with fabric, so the rockwool is mostly self-contained and relatively undisturbed while hanging from the ceiling, so I don't think there will be many fibers floating in the air. OSHA has a standard for daily exposure in the workplace. I have no way of measuring where I stand in my workshop, but I think I have a relatively low exposure to the mineral wool fibers.
+Wood U Make It there is a guy who said rockwool dangerous, he said rockwool should be full wrapped with fabric, and He said rockwool dust could cause cancer
There are a lot of things we use that will cause cancer if you're exposed long enough. I think rockwool falls into that category. These panels are fully wrapped in fabric , so I'm not to worried that they're going to cause me any harm.
+Wood U Make It yeah agree sir, i think eating fast food more dangerous than rockwool dust LOL. can't wait for my first acoustic panel
Nice build, though not too sure if i would have any use for one of those in my shed. The only thing hanging in my shed is the light, that's enough for me.
Hope you and your Family have a Merry Christmas and a Great 2017.

Thanks, Barry. I always look forward to your comments! That's probably my last video for the year due to upcoming travels, but you never know..... Best wishes for the holidays! -- Mike
Barry Roberts what a very helpful & constructive reply for anyone wanting to do this project. ps keep off the sauce!
What you recommend if I wanted to have mine standing up? Not on a wall
If you wanted to stand them on their ends, you could add some feet made from 2x4s, maybe about 18" long to prevent the panels from falling over. Alternatively, you could make a stand shaped like a triangle that would attach to each side. The apex of the triangle would attach about half way up the side, and you could design it so that the panel is raised up a bit from the floor, which might look nice.
Wood U Make It that would be a cool video to do.
you used the wrong insulation .. roxul safe and sound is the stuff you want to use.. you used the exterior insulation
not as good.. also safe and sound is sold as afb acoustic fire batt..
Shoot! I didn't even realize that I'd picked up the wrong stuff from the store (after researching it) until you pointed that out. Thanks! Even this stuff has made a lot of improvement though.
While it is the wrong material for an ordinary studio application, let's not forget that you're recording in a working garage, not a sound stage. I seriously doubt that there is any noticeable difference
massive difference...
It serves the purpose. It could be more effective though :D
Well safe n sound is wrong too. The Roxul you want to use for sound panels is Roxul rockboard. It’s different, it’s a compressed version of Roxul and weighs about 8 pounds per board which is why shipping is so expensive
Reflected sound waves gives it more of a concert hall reverb effect, to me it sounds better.
The appropiate acoustics depend on the end use of the room. Diffusion is a good option, where you keep a spacious feeling; a 3D sound effect while increasing the intelligibility of detail in speech and music.
I wrapped mine in thin plastic film to keep the fibers trapped.
Rendering them useless in high frequencies. The fibers will not move unless you handle the naked material. The binding materials are of higher importance; avoid formaldehyde. Knauf uses a environment-frendly process; ´Ecose´.
Shag carpet also works.
this video would be great if it wasn't for the 5 minute unskippable ad before it
uBlock Origin takes care of that unless you want to support the uploader. I´ve never encountered an ad I cannot skip after 20-30 s.
The intro was funny lol
Expensive! who has all those tools at hand? there must be an easier way to build the frame the frame!
you can call me marty
But it says Calvin Klein
Yes, I would make it. However, my wife would not let me hang. I need them in the living room to help dampen the echoes from the stereo system, but it’s a no go with her.
Change the wife.
Amish Gangster Models like her are hard to find now days. After 45 years, I’m kind of fond of her.
It's easy to build panels when you have a studio and equipment like that.Lot's of better DYI videos on youtube that have less emphasis on constructing the panels (and look better) without expensive tools that most people don't own. But these are great if you need them for your woodshop and have the means to make them.
no. i'd record elsewhere.
I don’t like the way you try to catch the wood as the blade is still spinning!!! I love the angle drilling clamp though!!
Haha, everyone have his tools...
I thought the same thing, no one has them. Im building a panel with frame now, and with no screws on the wall needed
Not a big fan of the reveal, I see. "Hi I'm Building something. Here is the project 1/6th of the way finished". The end.
Potential health issues,fibre floating around.
Hi there, is this a real problem? I'm trying to reduce echoes in my place of business and this seems like a cheap way to do it. People will never enter the same room twice and they stay there for about an hour, however staff might be in there for a bit longer multiple times. I don't wanna hurt anyone, is it dangerous?
Unlike Fiberglass, Rockwool is safe.
Hey Brother, wood I make it, yep, just finished making 12 of them for my home studio. Thanks for your great video!! www.danatucker.com/forum/viewtopic.php?p=20#p20
That's awesome, Dana! The panels have made a huge improvement based on the before and after sound at your site. Your wife must be very happy with all the work you've done. Congrats!
Thanks Brother! I spent the last 3 days, 5 trips a day to the dump, removing 16 years of pine needles and leaves. When we retire down here this fall, I will set up my wife with a little shop so she can build bird houses.
Small table saw, drill press, trim chop saw, craigs joint and varied clamps. I really love your videos and the last thing I need to build is a hidden door/bookcase going into the track room. I will use recessed hidden top and bottom pin hinges. They are good up to 800#s and guaranteed not to allow sagging.
I told my wife that she had to watch at lease 12 of your videos to learn shop safety. ;-)
where have your subscribers gone?
Are you concerned about fibers coming out of the panels, into the air, and into your lungs?
I would be concerned if there was something disturbing the panels, but they're just hanging there and not moving, so there is little chance of a significant number of the mineral wool fibers being in the air that I'm breathing. I've read that the mineral wool fibers are fairly large, so they're much less dangerous than something like asbestos.
I prefer the 1st intro to the vid. The 2nd one sounds like you're speaking into a pillow.
Ian Aintsaying lol you’re just wrong!
DIY but you need a hack of workshop tools...
oh bro. never use anything like fiber glass or stone wool for this. They must be sealed in your wall, not be in your room.
Dampening and absorption are totally different, low frequency,,, I can't be asked to explain,
Hi Everybody !
I'm a Real doctor !
my fridge to loud but i don't have a large clearance on the bottom .. doh

hahahahahah
Calvin Klein.
No I would not make it.
Cardboard is better, and almost free !!
Most overengineered DIY panel build on the youtube, congrats ;)
you should put a health warning on this dude. you are using a highly porous material to house fibre glass................?
Very fine airborne fiberglass particles can become deeply lodged in the lungs, causing serious illnesses including: Asthma. Regular exposure to fiberglass insulation can worsen a construction worker's asthma over time. Inhalation of fiberglass dust can even trigger asthmatic episodes.
This is mineral wool insulation, not fibreglass. It's advisable to wear a mask in the workshop in any case.
@@Woodumakeit copy that, lot safer. may i ask plz how effective is this mineral wool. because currently. towels seem like the best option
@@doctoronishispsychosislab1474 It's worked quite well for me. They make a specific product for sound called Safe'n'Sound. I'm not sure how it performs vs towels. Towels sound like a safe option, but they might be less cost effective.
@@Woodumakeit I found your video after watching this ua-cam.com/video/pABvTWSxOes/v-deo.html . yup Towels man who knew lol
