Andreas Hazir is investigating the door seal contribution to the interior noise level of
production vehicles. These investigations contain experimental contribution analyses of real
production vehicles and of academic test cases as well as the development of a simulation
methodology for noise transmission through sealing systems and side windows. The simulations
are realized by coupling transient computational aeroacoustics of the exterior flow to
nonlinear finite element simulations of the structural transmission. By introducing a linear
transmission model  the setup and computational costs of the seal noise transmission are
significantly reduced  resulting in the feasibility of numerical contribution analyses of real
production vehicles.
