For my LNC2 I soundproofed the area underneath the rudder pedal subfloors 
only.  This area is basically inaccessible once the floor is installed.  For 
all other areas of the plane, I plan to evaluate the noise level with an ANR 
headset.  If I'm not happy then I'll start adding more soundproofing, 
although I don't expect to need any.  For this reason I will do my initial 
flights without the interior installed.  (Plus, I expect to be broke at that 
time....)

I used a single layer of ADC-006, which is a thin foam with aluminum backing, 
stuck to the inner skin with the peel-and-stick adhesive it comes with.  Over 
that I put a custom shaped pillow of fiberglass batting with a vapor-proof 
heat-sealed cover (the vapor barrier is kinda like plastic tissue paper that 
you seal up with a household iron).  The subfloor goes over that.  

If anyone wants more details I can go look at the boxes to get part numbers.  
The minimum order was enough for at least two Lancairs, but it's still a 
small amount of stuff.  My recollection is that I only added about a pound of 
stuff (both sides combined).
