Comparison of Asphalt Melt Sheets and LASD Materials for Structural Damping of a Passenger Vehicle 2008-36-0391

The automotive vehicle is a system of high complexity in relation to the generation sources of noise and vibration. In order to achieve the overall vehicle NVH objectives, the damping treatment of the body panels needs to be optimized. Therefore the objective of this study is to compare the characteristics of two materials of floorpan treatments (deadeners): an asphalt melt sheet (bitumen pads) and a waterborne material (LASD - Liquid Applied Sprayable Damper - AcusticCol).
