Sedan Interior Acoustics

Application ID: 15013

This is a model of the acoustics inside a sedan, that is inside a typical hard-top family car. The model sets up sources at loudspeaker locations as well as impedance conditions to model soft absorbing surfaces for the seats, carpet, and roof lining.

The model results in plots of the pressure, sound pressure level, and intensity inside the car. These are important tools to visualize the acoustic field inside closed spaces and identify problematic resonances and standing modes. The frequency response at given points inside the cabin are also determined.

This model example illustrates applications of this type that would nominally be built using the following products:
