Cover my absorver panels with carpet

Hi, My question is: Is a carpet cover (without rubber) good for a 2 inches thick rockwool panel absorver or I must cover the panels with other kind of cloth? Thanks!

I would look into something else. Carpet is notorious for soaking up high frequency so it works against you in that respect.

But I don't understand whats the difference of: 2" Rockwool covered by cloth 2" Rockwool covered by carpet I think there are many DIY traps where people had used carpet: Is not that "black car carpet"? http://www.cloneensemble.com/basstraps.htm The carpet I want to use it's the same.

The cloth is only part of the panel / trap to hide the gaps in resonators. That is really it's only function, to make it "look good". The cloth doesn't alter the way the trap/panel performs. Carpet, on the other hand, will change the way it works. You are free to use it, but if you are having doubts, I would continue to read up on it until I was certain. http://www.johnlsayers.com/HR/index1.htm http://www.ethanwiner.com/basstrap.html

ok xSpace. Your advices are wellcome. Thanks.

I'm learning just like you:)

Exactly. the way I understand it, the purpose of so-called "acoustic cloth" is to be as transparent as possible to sound, and to affect it as little as possible. Carpet, on the other hand, is not designed with any such intention in mind, and will affect different frequencies in different ways. Now, that may or may not be a good thing, depending one what you actually need! It might turn, purely by luck, that the carpet has the exact acoustic properties that you need for your room. On the other hand, the chances of that just happening by chance are pretty slim! In order to find out, you'd need to do detailed full-spectrum analysis of your room without the trap in place, then repeat the analysis with the trap in place but no carpet, then repeat the analysis again with the carpet too. Only then could you determine if it helped or not. But just putting the carpet in there because you saw it on the internet is NOT a good idea. You need to have solid acoustics reasons to do it, or not do it, based on actual measurements. If you believe everything you see on the internet, then you could end up carpeting your ceiling and gluing egg-crates to the walls, and a guarantee you that your room would sound really bad like that! So I wouldn't bother using "ideas I saw on the internet" without checking out the acoustic theory behind them first, and the conducting actual tests to ses if it will work for you. - Stuart -

Could adding some acoustic tiles instead of carpet give you better results?

Once again, it depends on what problems you have in your room, what you are trying to treat, and the acoustic characteristics of those tiles. Once again, you need to actually measure your room, accurately, both with and without treatment, analyze what problems you have, and treat accordingly. You can't just guess your way through acoustic treatment. There are a few basic rules of thumb that you can use (such as "lots of bass trapping in the corners" and "absorption at first reflection points"), but to get it right you need to measure, analyze, and then treat the specific issues that YOUR room has, not the issues that somebody else's room had, somewhere out there on the internet. Every room is different. Every room needs its own individual treatment, if you want it to sound its best. No matter what you might read on the web sites of manufacturers of treatment who want to sell you "kits", with acoustics there is no such thing as "one size fits all". - Stuart -

The cloth, carpet or whatever is just the *finishing* tough of a panel. It's to make it eye-friendly. Unless you plan on making a bass only absorber, then you'd need some way to keep high frq from entering the panel. That can be done by means of adding a tighter/heavier front (cloth or anything else) or by adding a sheet of plastic in front of the panel and behind the cloth (which is just the finishing tough, remember). So whatever you need; it depends on what you want. But remember it should be fireproof.
