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:Acoustics Module CAD Import Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabela de Especificações and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
