I have some nasty echos in my family room which houses my home theater system. Hardwood floors, lots of glass (30%) and relatively bare walls. My wife has agreed to covering some of the bare walls with sound absorbing materials if that in turn can be covered with wallpaper. GOM or fabric may not be acceptable.
The room is 18x30 with 14ft angled ceiling. The rear of the room is open to the kitchen (18x15) and a hallway to the rest of the house.
The wallpaper is not extremely hard, but definitely stiff (but thin). I am considering covering areas with a .25" to .5" materials, some of which are recommended in this thread. My questions are as follows:
1) Will the wallpaper surface defeat the purpose here and be reflective?
2) Must I use instead a more absorbant fabric (GOM?) over the panels?
The paper isn't the issue as much as the adhesive that soaks into it and dries stiff which makes that paper so crispy. If you havce ever removed old paper without a steamer or the release agent, you understand the term.
I have seen some wonderful papers based on softer materials that look tremendous. It's just that they get stiff as a board when the adhesive soaks into the back layer of paper.
Some of the finest homes I have ever been in had expensive fine fabric with a wallpaper style pattern strecthed over the walls and suspended just off the wall surface. I don't know what this method is called, but then again I don't subscribe to Architectural Digest...
There was a little bit of deflection to another wall substrate if you pressed your finger against it. Something like this would allow you to use a thin duct liner of fiber panel material in the trouble spots determined by the mirror method or a ray trace.
This may be a better solution if you can give up a little more space and fit it into your budget.
3) Is .25" or .5" enough to kill the echo and give a relatively damp room? I could do about 35% of the wall area with it if needed.
4) Should I just cover the maximum amount of wall area I can with .5", wallpaper it and hope for the best?
Thanks very much. [/b]
.5" is better than .25", and .25" is better than nothing...
I am still not sure that fiber panels are the best solution for your application.
Even if the stiff paper didn't reflect, I doubt it would bond well to fiber panels.
If you research the stretched fabric method and it is not your wife's cup of tea, or it is a budget breaker, another option to look into is a skimcoat of acoustical plastering.
Nearly any plaster contractor in the phone book has availiability to acoustical plaster and understands it's application.
The absorption characteristics, and therefore the results, are based on variables like how thicky it is applied, etc. and an acoustician would generally specify these variables for it's use.

Another choice is a new system from Switzerland called BASWAphon that RPG offers in the US.
Famous acoustical guru John Storyk used this system on a This Old House project, and you can read about that here.http://www.thisoldhouse.com/toh/know...216779,00.html
Read the section of the article called "Mid- to High-Frequency Reflection Control" where he descibes a new product he used in that room.
As I said, RPG distributes this material, and you can read more info here:http://www.rpginc.com/products/baswaphon/
I am not positive if you can paper over this.
I'm thinking you cannot, because you actually don't even paint it.
You tint the plaster material before it is troweled and skimmed.
I would send out a letter to RPG to confirm.
Either this new material, or the skimcoat method with traditional acoustical plaster to a lesser extent, can help make a room less "live" yet still retain the traditional aesthetic apperance.
Either method should allow your wife to paper the space, but as I said, double check with the manufacturer of the panels before you order them.
If you want the best results (and some quality entertainment) call in a acoustician and an interior designer and let them battle it out.
Right now you and your wife are having that debate on a smaller scale, when it's two pros that are each dead set against each other's plans and both very good at what they do, it's not pretty...
