21. Tyre Noise over Impedance Surfaces - Efficient Application of the Equivalent Sources Method
Abstract : Reduction of the transportation noise nuisance has become an important challenge in today's societies. As a consequence of engine noise reduction, tyre / road contact noise is now the main source of traffic noise under normal driving conditions. READ MORE

23. Application of the Boundary Element Method to combustion noise and half-space problems
Abstract : The Boundary-Element-Method (BEM) is a powerful and established tool in computational acoustics. This thesis aims at an enhancement of the method towards combustion noise and half-space problems.First, it is directly coupled to an incompressible Large Eddy Simulation (LES) to calculate the sound radiation of open flames.

24. Modelling the vibrations on a rolling tyre and their relation to exterior and interior noise
Abstract : For most modern cars at normal driving speeds, tyre/road interaction is a major source tothe exterior as well as interior vehicle noise. The interaction between a tyre and a roadsurface generates tyre structure vibrations, leading to sound radiation into the surroundingair, and to dynamic forces acting on the wheel hub. READ MORE

25. A Vibro-Acoustic Study of Vehicle Suspension Systems : Experimental and Mathematical Component Approaches
Abstract : The objective of the present work is to study the vehicle suspension as a vibro-acoustic system of high complexity, consisting of many sub-systems with fundamentally different acoustical properties. In a parallel numerical and experimental modelling effort, important contributions to the understanding of its behaviour have been achieved. READ MORE
