I recently looked for some inexpensive solutions for sound treatments in my relatively, 50-year old home. I was able to buy some very good materials from a local marine supply company in Seattle. They will ship sound proofing materials, so you might want to check them out. Specifically, take a look at the product called "Sonolead", which can be mounted to peg board or similar material to make excellent baffles. I also used another product of theirs which is acoustic foam that has a vinyl barrier. Both of these products are essentially mass-loaded, constrained layer materials. Here is the URL for the company in Seattle (HamiltonJet), plus two others you should explore: 1. www.hamiltonjet.com/ 2. www.acousticalsolutions.com/ 3. www.noisebusters.com/soundproofing.htm Hope this helps.
Sound Deadening
I live in a condo that has less than satisfactory sound insulation between me and my neighbor. I rarely hear my neighbor, but I suspect that they hear me quite often =] . I own the place, so I am not opposed to doing some major modifications (hopefully inexpensive). I found some good stuff at: http://www.owenscorning.com/around/sound/products/index2.asp but I am wondering if anyone else has any other information. Thanks!!!!
