Dissipative Sound Package Systems

This article discusses the importance of dissipative sound package systems in the automotive industry and how they work. Although this is not a new technique at this stage, it is still a challenge to meet subsystem target levels that were originally developed for parts based on the barrier-decoupler concept. We will review the typical construction of a dissipative system and then emphasize the importance of different layers of materials that are used in the construction, including what they can do and cannot do. We also also discuss the importance of proper manufacturing of a part.
