i have about 100SF of CCF in my garage. maybe i should do some testing with it. maybe in a test enclosure? or snag a door from a junk yard for cheap? if i do that, then i could experiment with various amounts of deadener/fill and RTA each. hmmm...
i am more interested in trying a variety of door fill materials. but only after deadener coverage area tests. i see the tests as follows
1. as-is factory door
2. holes closed/sealed (removable), no deadener
3. 25%, 50%, 75%, 100%, 200% coverage with/without holes closed. - tests would be RTA and ASTM resonanace testing
the tough part would be deciding what deadener to use, then justifying spending ~$200 on deadener for a test.
I did find those ASA papers on car door testing - but my license for them does not extend to public sharing. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
