Phil, There are a lot of issues with noise sources that can complicate your solution. Secondary vibration from the fuselage plywood and the plexiglass canopy and even the fiberglass turtle-deck can combine to make considerable noise. While you might not be able to address many of the causes, the use of soft, noise-cancelling foam covered with light-weight cloth might help a lot. Using the stiffer foams covered with thicker upholstery-type material might look prettier, but is less effective when it comes to deadening the sound that vibration causes in the cockpit. Also, you are faced with the problem of not adding too much weight or anything that might come loose and get tangled in the controls. A lot of folk just think the noise is all part of the fun of flying. Good luck, Frank
