I also used gasket material and a flat sound mat in the aft berth from Soundown.  They also sell the same type of stuff WM has may be able to get a better price. They are great to work with and made some good suggestion.   http://www.soundown.com/index_Marine.htm.  I can not tell you how big a differanceboth made.
