Structure-borne excitations are significant contributors to vehicle interior sound and vibration. Damping treatments applied to the body panels dissipate vibration energy and reduce interior levels of sound and vibration. This paper compares the performance of sprayable dampers and bake-on sheet dampers by considering the impact of material application conditions. Detailed characterization of viscoelastic properties is performed to clarify materials' response to specific baking conditions. The impact of applied material distribution on damping properties is investigated.
