Geometrical Acoustics is a widely used room acoustic modelling method. Since GA neglects the wave phenomena and is strictly applicable for short wavelengths relative to model and surface sizes, the application for the automotive industry is still subject of research. The paper studies the feasibility of using GA for high frequency simulations of a car sound system. The GA models of a vehicle at three production stages were created based on FE models. An impedance gun was used for in-situ measurements of the properties of the car interior materials. The directivity of the midrange and tweeter speakers was measured in anechoic conditions. In subsequent simulations, various GA software settings were tested. Simulation results were verified with measurements in the car.
