Hey Paul! I'm certainly trying to understand the fabric issue in more detail haha. Jennifer definitely has a point in just using tried and true materials. I'm just finding it hard to source things right now due to COVID, so I'm looking at all potential options. Glad it's been helpful! I will post mo...

1927 Perhaps then what you are wondering about is absorption properties of the non porous felt material itself? Will that be sufficient to absorb the high frequencies while the insulation inside deals with the low? I found this information from a manufacturer of felt; Yes! Essentially that's what I...

1925 It seems to me that breathability and and GFR and related. Low GFR ~= high breathability. I think the polyester batting will be fine. Jennifer, thank you again! Your reply came right in time...I was just about to walk into Joanns. It was helpful having some insight before walking into the stor...

Hey Jennifer, thanks for the reply! So I’m curious about that polyester batting that was recommended by Starlight that I use behind the burlap if I went that route...that stuff sure doesn’t look like it would pass the air test. It’s like 3/8” thick which is the thinnest I’ve been able to find! But S...

Thanks again for the reply Starlight! Much appreciated. I talked to a staff member at Joann about that “Knit Jet Set 2” that I linked to above. Apparently it is not very see through, but it is stretchy, and it doesn’t pass air on the “blow” test. She was super nice and said someone else that day cam...

Hey Starlight, those are all great ideas! Thank you for the reply. I've found one more online but wouldn't be able to test in person. https://www.efavormart.com/products/10-yards-54-wide-charcoal-gray-polyester-fabric-bolt I've also heard breathability isn't always necessary depending on what the fa...

Alright, so I am having the hardest time sourcing a good burlap. Due to COVID, a lot of places are low on stock and out of the colors I'm interested in. So, I'm looking into other fabric types. I'm going to link below to a couple things from Joanns and if anyone has the time please let me know what ...

1899 There are: polyester batting has a low GFR and will not reflect any high frequencies. Thin plastic is not wrong if what it does acoustically is what you are wanting. Thanks for the clarification! I did some more searching and found a thinner polyester batting at Joanns for super cheap! It's th...

1897 1) Unpredictability. It may be beneficial acoustically. Or it may not. Large areas of broadband absorption can absorb too much high frequencies relative to the lows, and plastic covering will restore those. But would it be the correct amount? If it restored too many highs, it could be too late...

1895 I think there is significant leeway in what will work, as long as you are in the ballpark. The insulation I've bought is "Knauf Insulation Earthwool Combi-Cut Loft Floor Insulation Roll 44 170mm (4.90m²/Roll)". They cost the equivalent of about $15 each, and you'd need a bit less tha...

1886 Rather than black plastic, how about using polyester batting/wadding/filling (it seems to go by a few names) behind the burlap or whatever textile you choose to use? Is there an acoustical reason behind using this material instead of the thin black plastic? It will cost me WAY more per panel t...

Also, I'm having a very hard time sourcing a good fabric at a decent price. I've been to so many stores locally (including Joanns) and the prices have been absurd other than burlap. But after making one test panel with some burlap from Joanns, I was not pleased. The weave is just too loose so you ca...

1876 So there you are Trevor. If you're inclined towards this sort of thing maybe you could figure out a way to get a mic into that chimney stack Yes! That is a great idea hahah. I do love the sound of a random DIY reverb chamber lol. We've always joked about putting a mic in that chimney but I jus...

Thanks again for the great info Jennifer! Really appreciate the effort. 1874 Reason being the asymmetry at the rear of the room caused by the door being right in the corner. The panels will allow you to try out various schemes. I've personally observed sonic irregularities from asymmetrical bass tra...

Would something like this work? It's 1.57" thick made of solid wood. I'm guessing it's not enough since that likely won't match the sound isolation of the walls. Could I just reinforce something of this price range with some dense material before hanging? Also assuming this could be made into a...
