Erukian Posted January 23, 2005 Share Posted January 23, 2005 Hi, I live in a room that's 10x12, which is a large dorm room by most standards. Anyhow, When my window is closed and my door is closed, my room likes to ECHO. Like the sound of walking through a new house or room with nothing in it. I have no posters in here or anything, just a plain white wall. What can i do to get rid of this? What are some options bsides putting up curtians on my walls?

dodger Posted January 23, 2005 Share Posted January 23, 2005 Room sized throw pillows. Tapestrry wall hangings. Changing speaker placemnt. Sound absorbtion panels. Thick Carpet. Heavy blankets on bed. Fabric wall paper. Add fabric covered chairs. Heavy curtains and drapes on windows. Use of treble control. Towel racks and thick towels. Egg crates. Foam Padding or bats (round). This is just a start. But the thing to remember is what you do to stop echo when windows are closed wil affect sound when they are open. You can make some wooden frames and glue foam or fabric to insert in your windows. Experiments with closed windows sytem in use will determine how much fabric or foam. You can always add some velvet paintings of Elvis. dodger Quote Link to comment Share on other sites More sharing options...
Klewless Posted January 23, 2005 Share Posted January 23, 2005 You might also consider different sized pictures on the wall. Pictures without the glass. Overstuffed furniture in the right place can help. The problem is solved by a combination of absorption and/or scattering of the sound waves which are bouncing back and forth all over the place. You can experiment a little bit with the hand clap test. Walk around the room and clap your hands over your head and listen to what happens. Do this each time you add or subtract or move something within the room. Good luck! You can go too far, so do things one at a time. Your room could sound too dead (clap your hands in a closet to experience dead sounding room). Quote Link to comment Share on other sites More sharing options...
seti Posted January 23, 2005 Share Posted January 23, 2005 I hadn't thought of velvet pictures as sound absorbtion brilliant. I am going to cover every inch of wall in my audio room with velvet elves.....Bloody brilliant..... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=433&item=3867994389&rd=1 Elvis didn't die he just went home.

artto Posted January 23, 2005 Share Posted January 23, 2005 How man! You have just opened a bag worms! And so many "creative", but actually inappropriate responses. Your're best bet in a small room like that is to just let the furniture do the work. However I suspect you're in no position to be buying a lot of overstuffed furniture. Try this: http://www.americanmusical.com/sort--m-h--s-auralex.html Prices vary from as little as $3 to $600. Something like this should be a great start, if not adequate for your situation: http://www.americanmusical.com/item--i-AUR-2WD24CG.html ($70) DO NOT USE: egg crates/cartons, closed cell foam (like used for packing), cardboard, paper. Things that are too "thin" such as many curtains/towels will not absorb enough, and when they do, its usually in a very narrow frequency range (bad). Things like "velvet" artwork are far to thin to have much absorption quality although they may provide some diffusive qualities, as do book cases/shelves. The room is small to begin with so you can pretty forget about anything even close to "perfection", which is probably not your objective anyway. Use the KISS method Quote Link to comment Share on other sites More sharing options...
Erukian Posted January 23, 2005 Author Share Posted January 23, 2005 Jeez, I dont want to wrap up my room in sound absorbing material like a movie theatre. If i'm going to hand up stuff behind me, would the best spot be where the drivers are facing? should i worry about reflections on the left and right walls? Also if i invested and bought all those corner/wall sound blocking stuffs my girlfriend will think I flipped out of my mind. Quote Link to comment Share on other sites More sharing options...

Suggestion of velvet painting was tongue in cheek. I noted heavy curtains and drapes. But if the source area is the side that the window side, sound absobing panels such as those used in an office should be effective and can be found in used office furniture outlets. dodger Quote Link to comment Share on other sites More sharing options...

Second, you probably don't need much sound absorbing material as a start to accomplish what you want. A few 2'x2' panels strategically placed should do the job for what you want to do. So would a book case filled with books, or a heavy pleated curtain, etc. You first need to locate the primary "first points of reflection" relative to where you usually do your listening. While you sit, have someone (maybe your girlfriend?) take a small mirror (6" will do) and have them place it flat on the walls and ceiling, moving it around, until you can see the reflection of the speaker (primarily the midrange/treble) in the mirror. Mark these locations lightly with a pencil or something. These are the first locations where sound absorption or diffusion should be placed. The 2'x2'x2" acoustical foam panels mentioned above should be enough to take out much of the "echo" in the room, as well as reduce short duration reflections that interfere with the direct sound from the speakers. $70 worth should be plenty in that room. Better now than later that your girlfriend find out you're already addicted to this sport. And I can assure you, all your campus pals will think its really cool.

D-MAN Posted January 24, 2005 Share Posted January 24, 2005 Do the sound-absorbing panels up with picture wire and hang them on the walls like paintings. Adhesives will generally damage the walls. That way you won't incur any damage charges when you leave, and you take them with you. DM Quote Link to comment Share on other sites More sharing options...
jacksonbart Posted January 24, 2005 Share Posted January 24, 2005 I would recomend that you invite over (given the room size) about 20 hot college babes and the crank the music, should make an improvement. Quote Link to comment Share on other sites More sharing options...

DM ---------------- This is even easier and less damaging: use 1-1/2" or 2" straight steel "T-pins" available at some office supply stores or fabric stores. It literally leaves a "pin hole" Quote Link to comment Share on other sites More sharing options...
