[Greenbuilding] Noise between floors

[Dusch, Jim E]

This generic mitigation question is a good one for new and existing
construction since most of the products I have been aware of are (1) not
very effective unless installed in new construction and (2) the more
effective they are, the less "green" they are. 

To the extent it's considered env. friendly, I have wondered about ATF
application of Icnene between joists to dampen heel strike as well as
ambient transfers.  Also, if carpet padding works, what do folks
consider to be green and proven brands.

& Is this the same thing as (or similar to) sound board? 
& 
& We have a similar "drum" situation in the house we are 
& building, with bedrooms over kitchen & living room.  We 
& milled our own beams and thus have left them exposed as 
& joists, with a 1-1/8 sturdi-floor subfloor.  
& The plan right now is to put a wood floor over that and then 
& a good thick rug in each bedroom.  From the bottom, between 
& the big joists, I'd like to add 1/2" sound board and then 
& exposed paneling, or something fancier if more time 
& materializes out of thin air. 
& 
& However, I have zero faith that any of this is going to stop 
& the "drum" 
& effect.  It isn't the end of the world, but if there is 
& something inexpensive I can use to mitigate it, I'd be 
& happier doing it now than later.  How much would an underlayment help?
