Sound Absorbing Material

Stuffed furniture, with cheap great-looking, thick pillows found at Marshalls, etc. Plop 'em up to absorb sidewall splatter; knock 'em down for instant WAF! Ern

As good as any other material including the more expensive foam products is very inexpensive Owens Corning #703 1in fiberglass panels that can be covered with most any fabric from $2.99 yd burlap to $25 speaker cloth to anything in between from the RAG Shop and be hung on the wall like a picture. Best to leave an air space between #703 fiberglass panel and wall. Can even make low and high bass trap absorbers that absorb from the 60hz to 300 range for only 40 a trap which will be much better than the expensive round common tube traps from the famous manufactures. The foam mentioned also works but cost more and is more diffulcult to cover. Try this link for plans ------ Build a Better Bass TrapAddress:http://www.ethanwiner.com/basstrap.html

Two more are fiberglass and Sonex. audioadvisor carries sonex. You can use fiberglass to build your own.

Thermafiber (compressed fiberglass panels)will do the trick.

Cover it with some thin cloth...

I built several baffles for my listening area using panels called "Sonolead", which is two layers of high-density fiber glass with a thick, flexible vinyl material in the middle (like a sandwich). "Sonolead" panels were designed for use on marine diesel engines, and they REALLY cut the noise. I purchased these panels, plus other sound absorption material, from a local marine supply store. If you have a good marine supply store in your area that carries engine and engine room parts, you can probably find "Sonolead" or something similar. If you don't have a local source, my local store ships anywhere. The name of the store here in Seattle is Hamilton Jet, and their Web site lists a number of sound absorption materials.
