is it safe to say, regardless of what type of insulation you use, you will still be breathing in some of this crap into your lungs. thinking seriously about bypassing the acoustic panel thing for my theater room.
We understand the safety concerns that folks have with these materials. But you should be good as long as you use a fabric like Duck Canvas. You're definitely not going to breathe in any loose particles as long as your panels stay hung on the wall without being shaken. Of course, no one's gonna go around shaking those things out intentionally. If you're still doubting the safety and want to make extra sure, you could add a thin membrane/plastic wrap before you wrap it with any fabric. This will guarantee safety 100%! Hope this helps!
I wrapped the rock wool in my panels in a thin plastic foil. They still work perfectly fine as absorbers. That was probably overkill, though, because as long as you don't play around with your absorbers all the time, rock wool doesn't just spontaneously blast fibers into the air. If you want to be completely sure, use sheep wool. Definitely _do not_ skip acoustic panels in your theater room. if you do that, half of the money you spend on speakers is basically down the drain.
You need to find a wrapping material that lets the air through nut not the fibers. I used Gartenvlies, as it's called in German. I don't really know the English word, but Google thinks it might be called Vylene. It's not very tear-resistant, so you probably need to wrap it again in some sturdier material. Burlap comes to mind.
I made my acoustic panels, almost identical to yours, about a year ago. That jig you made is excellent! Great idea for someone want to mass produce. Great video!
Hi, I’m planing to do some absorbers with with wood frame and acoustic rockwool inside. You say the fabriv has to be breathable to let the sound pass, but I’m afraid it will also let particles of rockwool pass trough and then we will have them in the studio?
You can add a thin layer of plastic wrap between the rockwool and the fabric. This will help keep any loose particles trapped. The only thing is the plastic wrap will reflect some of the higher frequencies which isn't a big deal in most cases. You also have the option of Recycle cotton material which is 100% safe and ECO friendly. You don't need to use plastic wraps for cotton.
One of the best vids for building these. Man, can you give plans for that jig you guys made, thing is awesome. Would tremendously help with my build I am going to do.
If this was not posted already I was planning to if you had plans for the jig, and if you were thinking of making a video on how to make it. That jig is awesome and I have so many panels to make investing the time in the jig first would totally be worth it.
As i understand it correctly, using a carpet instead of fabric would lead to less efficient absorption? I used it in the past and the acoustic panels covered with carpet worked alright, i'm just wondering if it could be more efficent.
It all depends on the type of carpet material you're using, its mass, and porosity or transparency. If it is adequately transparent for sound passage, then it would work well without overkilling the room sound or underutilizing the core material.
Where can you buy a single package (5 to 6 pieces) of the insulation? All my local Lowes, Home Depot and Menards sell them at a minimum of 8 to 12 packages.
Unfortunately, this is how most retailers sell that's usually if you try to order online. But you can try to walk in store at Lowes. They sometimes allow single purchases. We get that at our Lowes local store here.
Great video and nice jig. I have been thinking of using rigid foam board insulation as a frame. Its light weight and the panels would be easy to put up and take down. What are your thoughts about foam board?
@@neptuneaudiospace I checked out your site and I liked your way of cutting out a hole in the foam board and stuffing the insulation inside. Foam boards at Home Depot are 1'' or 2'' thick, so you may need to double up and that may get a little expensive. I was thinking of ripping 3-4'' wide sections and gluing them together like a traditional sound absorber is made. You may get two or more panels that way.
Absolutely, doing it the way we recommended will build up expenses. So cutting out wide sections like you said will work perfectly fine! That way, you get more for less money. Thanks for sharing your thoughts. It's such a cool idea!
Great video! I have a question. How do I make really large panels that cover whole walls without spending too much money? In a rented space where drilling is not allowed
Use 1x6 as the frames and they can stand upright on their own on the floor- no need to hang them on the wall. Also, if you fill the inside with 4" thick insulation up against the front of the 1x6, the leftover air gap between the insulation and the back of the panel will give you some extra low frequency absorption That's what I did and mine are all about 6 ft tall and haven't fallen in 10 years.
Can I just staple insulation to the wall? And do I leave the chrome foil against the wall or showing. Got it free after they built the house down the street. The pink stuff. R30 whatever that means.
Sounds like you're talking about Fiberglass insulation. We recommend that you wrap this insulation in fabric before hanging it on the wall. Even if you don't want to build a frame for it, at least wrap it in fabric, using glue. Hang with Velcro or Command Strips. You can leave the foil thing against the wall. The R-value means the thermal resistance. Really has nothing to do with the sound but the heat flow.
Yes, and while that is true, the R-value does not necessarily translate to better sound absorption. But rather after the sound is converted to heat, how much is the material able to regulate heat/cold flow through the seasons. Home builders look out for R-values while audiophiles look out for NRC values. Hope this helps clarify
@@neptuneaudiospace I have a crazy idea and want your thoughts...What if I built a frame and inserted random foam blocks......Could such a device be both a absorber and diffuser?
Technically, that would still be considered an absorber. But if the foam blocks have high density and are rigid, and are placed at random/ mathematical patterns, they would work as an absorption/diffusion panel
Yes, you can definitely use memory foam. Although, it may not be able to perform much on the low end. But you will certainly get a nice dampening effect overall.
DIY and than they pull out tools that would never be in possession of a normal mortal, this is more of how it's made than make it yourself. Amazing work though don't get me wrong
You do have a big point right there! We'll be working on a video for those who do not have access to these types of tools. The video will feature simple crude household tools everyone has. Please stay tuned!
We used the 3/4-inch thick MDF for this DIY. You don't need to go thicker than 3/4 inch. This thickness already provides the perfect amount of absorption support needed for the lower frequency
We don't feel the crucial need to do so at times, since we're gluing crossbars to those areas anyway. Adding glue to the corners would then be optional, as the glued crossbars already contribute tremendously to the overall strength. But if you’re not going to be adding crossbars and brackets to the corners, then it would be necessary to add glue on the corners, even though your frame strength still wouldn't be anywhere near the strength that crossbars provide.
First of all. Thank you. Everything is very detailed but to the uninitiated the trimming part.of boards and explanation is too fast imo. Once again thank you for posting. Do you have a set of.written instructions?
Thank you for your comment!

According to Dennis Foley at Acoustic Fields, your method of controlling frequencies between 30-150 Hz doesn't work. Have you ever measured the results of your method? Thanks for the great video!
Excellent. I'd love to see what you come up with. A suggestion: Perhaps specify the frequency range your panels can handle in the video. Perhaps you did and I missed it? Apparently, if the subwoofer range is not properly dampened in a room, the mid and upper frequencies can be muddied as well.
if you find some weirdo in walmart sniffing fabric in walmart, they are not creeps, just audio engineers out of their familiar habitat finding materials.
I think DIY for professionals not for individuals living in an apartment. Neither this materiels will cost that less (as you spesified in the description) nor I have any of the tools that you use for cutting etc. Oh wait except sticky roller, because I have a cat.
I totally agree! You do have a big point right there! We'll be working on a video for those who do not have access to these types of tools. The video will feature simple crude household tools everyone has. Please stay tuned!
Caruso Iso Bond, Basotect or Rockwool are all great to make Absorbers. Baso and RW shouldn’t be too thin to cover low frequencies. Baso and Caruso are better for health and better for cutting because you don‘t need gloves
Sorry how you feel about that, sir! We just love that fire cracking sound so much! Even though we knew not everyone would love the sound. Maybe went a little intense with it. You can turn down your volume if you'd like. We'll try reducing that sound for subsequent videos so guys like you can be happy!
Duck canvas are so wrong they are extremely tight weave and not transparent for acoustic fabric , thanks for fukking up my acoustic panel now I have to undo all goddamn panels and find correct fabric

He’s using rockwool, not fiberglass. Its safe. You can also use aglomerate poliuretane stuff and cotton waste.
@@pillmuncher67 In the US, we call it landscape fabric or weed barrier fabric. There are probably other names as well.

Great. Can you send a link to the 4" Rockwool?
Hi there, does somebody know,if the wood fibre insulation called : "steico flex"
works as well or maybe better than rockwool ?
Thx for your reply ✌🏻

Hi Neptune Audio, what thickness of your MDF board are you using? Thanks Joe
3/4 inch
Excellent
Great video! I have a question. How do I make really large panels that cover whole walls without spending too much money? In a rented space where drilling is not allowed
Just make several smaller panels and lean them against the wall next to each other to make a large panel. They dont have to be on the wall

Also, if you fill the inside with 4" thick insulation up against the front of the 1x6, the leftover air gap between the insulation and the back of the panel will give you some extra low frequency absorption That's what I did and mine are all about 6 ft tall and haven't fallen in 10 years.

We used the 3/4-inch thick MDF for this DIY. You don't need to go thicker than 3/4 inch. This thickness already provides the perfect amount of absorption support needed for the lower frequency
How heavy does one panel end up weighing?
Anywhere from 15 - 20 lbs depending on the wood density.
why do you not glue the four corners? just only screws?
We don't feel the crucial need to do so at times, since we're gluing crossbars to those areas anyway.

What is the thickness of the MDF which you have used?
We used a 3/4 inch
Wow that's way too much work . Just pay extra and save time. Time is priceless.
Ni un huracán destruye el panel
Is duck canvas fire retardant?
No, it's not
This video had everything except ways to hang the panel.
Just use lots of liquid nail and hold it until it dries (sets).😂
MFD is really heavy I wouldn't use it
It's not about weight if you want the best insulating panel.
Diy acoustics needs to stop recommend glass/mineral wool.
Why use screws, which vibrate and add to the problem, instead of wood dowels
Wooden dowels are a good idea but the effect of the screw can be negligible. We build in bulk so time is precious.
