The reduction of vibration and sound in the passenger cabin of vehicles is part of what defines a luxury product. This research aims to provide robust design tools for simulation, taking into account the natural variability of the design during manufacture. It covers the design of typical transmission paths for low frequency, structure borne sound, numerical simulation methods and variability in measured frequency response functions.

Typical passive damping materials and techniques for low frequency waves have tended to be heavy and bulky. Through modification to the properties of a structure, highly efficient and optimised vibration damping methods can be realised. This research extends the principle of continuously variable bending stiffness and loss factor in a plate structure to continuously variable grading of properties, for example through reduction of an incident wave velocity to zero close to a free edge using mathematical profiles.
The research has demonstrated highly efficient damping of flexural waves in thin plates, future work is continuing to extend this towards acoustic waves using localised changes to the admittance of air. Possible applications include lightweight and low environmental impact noise barriers.
