I used Cara fabric on my panels and the results look far more professional than my modest DIY skills would suggest. It ain't cheap but it is easy to get a decent result.

+1 for that.
Not sure where you're based, but someone in London was selling a stack of home-made treatment panels in the small ads earlier this week >>>>

Ok, so as mentioned I am going to make 3 panels from the 2 existing ones.

This will mean 3 panels 80cm wide, as I mentioned in the earlier post it was my hope to fire down the room from the chimney breast end that has now changed, it will be the other way around.

I just wanted some advice on where the panels would be put to best use, ie I have 4 possible spaces and 3 panels, here is diagram of room https://drive.google.com/file/d/1ZydUIy ... R-PpS/view ( hopefully that link works if not it can be found on page 1 of this post. I am aiming for the 25/30% coverage that Hugh suggested.

Thanks

You've really got to do the left and right mirror points. So the debate is just what to do with the third panel. The back wall/ chimney breast, the front wall behind the speakers, or as a ceiling cloud? I'd try all three and see which works best.

Thanks Hugh,

Just to clarify "Mirror points" does this mean anywhere on the walls or in a specific place ?

I will be performing/recording in front of chimney breast, firing down towards workstation, so just wondered if panels should be near where I perform or down at workstation end.

Also would it be an idea to record some audio as I go along for reference ? Was thinking this may be something I could share here, to get feedback on how the sound changes, as I alter things in the room ?

Mirror points are the points where the reflection of the monitors would be visible if you placed a mirror there. In a empty room there would be one on each side wall, one on the ceiling and one on the back wall (and. in theory, one on the floor I suppose but as that's not a practical place to put an acoustic panel........ and the desk usually breaks that up though that surface can throw up it's own issues).

You'll probably need to deal with the tracking ind of the room separately as I said up-thread :-

In a small room the flutter echoes between walls and between floor and ceiling are usually troublesome so some treatment either side and above the talent (and a sound absorbing backdrop as mentioned) will give you a better chance of getting decent sounding recordings.

Just wondered if anyone can help, I'm looking to order the cara fabric but want to make sure I order the correct amount of linear metres.

I was told the width of fabric is 1.70 - cost £12.54 per linear mtr, I don't know if this is a good price ?

As mentioned above I am looking to make 3 panels 1.82 x 0.80 this measurement doesn't take into account overlap, around the edges, which is around 3 inches.

If anyone can tell me how many linear metres I need I would be very grateful.

You are going to need nearly 2 metres for a single panel, you will have a fair bit left over off the width. My panels were (mostly) just over 1200mm x 600mm and 50mm deep* so I could use the width most efficiently and each panel used about 800mm linear.

* Built around 1200 x 600 x 50 mm Rockwool panels with '2 x 1 PAR' timber frames

What depth will the panels be? This can make the difference between being a perfect fit for the fabric or tipping it over into the frustratingly-just-too-big category. :)

Cost-wise it sounds about right to me. As Sam has pointed out the dimensions of your panels means you'll have a fair bit of waste unfortunately. The only thing I can think of is that if they are 800mm wide, then you could potentially do two with a single width of Cara, but it will only leave you with 50mm to play with on each panel, so that won't be an option if you're planning on wrapping all the way around the side of the frame.

There are probably ways to make it work, but it'll likely mean altering your design a bit. If you were making a large number of panels then the saving could be pretty significant, but for three then it may not be worth the bother!

An additional strip wood frame over the fabric might work, it could also hide the mounting brackets?

I have a room of similar proportions -a bit bigger, but with a similar issue where a window sits almost in one of the mirror points.

I followed the very helpful SOS portable absorber guide (link below) to make up some panels for wall mounting, then made a couple of extra ones with feet and solid backs, so they could sit on the window sill when the need arises. They can also be deployed as gobos/screens for other recording tasks.

Am I right in thinking that this allows for covering the back as well as the front? You can save a bit of money by using hessian on the back.

I usually get my Cara fabric from Soundproofingexpert on eBay but it looks like prices have increased a bit since I last bought some so your price looks pretty good - especially if it includes VAT.

I used weed blocker material on the backs of mine, cheap, breathable and stretchy enough to be easy to work. If it wasn't only available in black I'd have used it all round! :)

I used cheap decorators dust sheets on the back, if I'd been strapped I'd have used it on the front as well.
