I posted a similar message a couple days ago, but I was asking specifically about theater curtains at that time. Now, I'm just trying to figure out what's the best way to improve the acoustic properties of my "live"-sounding room (intended for home theater). Here's a diagram of my home theater. My floors are concrete, and all the walls/ceiling are drywall. In the figure I put 2 possible locations for curtains, but I'm open to other suggestions as well. Someone mentioned previously that I could have bookshelves with randomly-sized books on them, for example. He also mentioned installing an area rug. My wife's not keen on the rug idea, because we have a "designer" concrete floor...acid-stained with a funky orange/white swirl. I think I could sell her on a rug that doesn't cover the entire floor area -- for example, a rug that started in front of the TV, ended at the sofa, and left a foot or two of concrete on the sides. Such a rug would cover about 60-70% of the area of the concrete. Would this level of cover likely provide a noticable reduction in reflection? I'm also interested in what -- if anything -- I can put on the walls to deaden the sound. The requirement is that it can't just be patches of material placed in a few odd, anti-symmetrical locations. My wife wouldn't go for that. Are there any attractive wall-coverings available that has reasonable sound-deadening properties?
