Simplified analytical models for prediction of vehicle interior noise

The present paper describes some preliminary results in the developing of simplified analytical models that could be used as effective engineering tools for prediction and mitigation of vehicle interior noise. The structural simplification is based on understanding the physics of both generation of predominant modes of structural vibrations at particular frequencies and radiation of sound by vibrating surfaces into the vehicle interior. It is expected that the proposed approach will lead to the development of effective analytical tools that could be suitable for use on a design stage.
