I'm going to assume that you are asking which of the two materials you listed are best at absorbing sound vibrations.  There are many methods, the two you listed are valid, albeit a bit primitive, but the link that I have included below may help you much more.  (Cork soundproofing can be quite expensive, btw.)

Well for sund waves you can use the tuning fork and cup of water demonstration. As the water absorbs the sound waves it will ripple with the same vigor as the tuning fork. As far as light waves you can use the same glass and direct a flashlight through it to show how the water bends the light. Hope this helps.

I'm not familiar with this material, but sometimes websites that give info on materials and compounds include IR-specs.  Or, if you have a sample, call your local university.  Some one may be able to help you there.

cotton, nomex, leather, asbestos (but not anymore)

carbon fiber.\nit comes as a soft material rolled up like cloth, then they cut it and put it around a mould. It is hardened by putting it under a vacuum, and then in a huge autoclave which cooks the material. the result is strong yet light carbon-fiber

Wow, thats a tuff one. Have you considered cardboard or wire and fabric? How much time do you have because this seems like a time consuming task. You could look on the internet fo ideas that might help you out. It depends on what you want it to look like.

You can't find one that easily, I'ld advise you to talk to a realy good carpenter whose been a carpenter for more than 10 years and ask him to go through your wood list with you and tell you which types of wood absorb faster or more than the others.

with a lint free cloth and an anti-static foam(alcohol based not water).

Yes. Try a cork and a hammer.

hi, \n\nacetone will do the job nicely.\n\nbe careful, though, it essentially is making napalm.\n\nhere is a list of the effects of variuos solvents, though i think it's on bulk polyurethane, not the foam:\nhttp://www.rimnetics.com/rimsolventsheet.htm\n\nanything there that says breaking, collapse or degradation would probably eat the foam up.\n\ncheers!

I believe that is one of the available silica textiles.  It is likely the small rectangle of material I purchased to place beteen a wooden wall and a copper pipe to prevent a fire when I had to use a butane torch to solder (sweat) a copper fitting an inch away from the wall!  Worked great and it was reusable (many times).  It has an aluminum backing for strength and moldability.
