Summary:

Body cavity fillers are used to inhibit noise propagation/amplification through body cavities such as sills, pillars, and posts' to improve vehicle NVH performance. Cavity fillers should be optimized by matching their performance with the global NVH objectives of the vehicle. A standard test method must be defined to acquire acoustical profiles and facilitate in the proper selection of materials based on performance. This paper discusses test results of 38 cavity filler samples which represent all currently used materials by the "Big Three" automotive OEMs. The samples were grouped into 4 categories based on their weight and fill configurations. Data was obtained utilizing an established, laboratory based, acoustical test method for fillers (SAE paper 930336). The laboratory results were analyzed to generalize the performance of cavity filler materials and to set acoustical goals for vehicle applications
