  3. Abstract:
  4. The acoustical system of car was analyzed using finite element method (FEM) and identification of the system. The acoustical model of a vehicle was proposed and by using FEM modal analysis, acoustic modal analysis, structural modal analysis, and coupling modal analysis was performed successfully. The influence of the acoustic system on the driver ears to understand these effects were also shown. The methods and results can be applied to a vehicle design procedure for conformability of the human being when riding
