......in the "old days" we used to use lead foil on the floor of a Bus/Hearsts/MH to cover up the noise.....now that is not considered cool/legal/GREEN/healthy at all-even though we covered it with roll rubber and bonded it to the metal all around all 4 sides....times have changed....there are some expensive methods of eliminating noise on the market now.....but follow DOC Weaver's common scene approach and you have the same thing only at 5-10% of the commercial price-Doc understands sound [likes of which, I will never hear again] more than most understand what they eat for breakfast......some of the newer sound deadening materials are running upwards of $7.50 a sq.ft.....forgetaboutthat! If you want to learn about sound abatement I'd suggest you build a small lead box-drop a 6vt buzzer with batteries on and put the lead lid on....NO SOUNDS AT ALL.... When I was in S.E Asia there was a need to have meetings in rooms that voices couldn't be heard or broadcast from....the use of lead foil was very common and that is where I learned from the install crew how to control noise and radio interference......neat-but useless in civilian life-till now...Would I have lead in my vehicle now?....I have a lead foil floor in my Dodge PU since '92 and don't have any elevated lead levels.....but will remove it when it comes time to let it go.......geofkaye
