Acoustics Module
Condensor MicrophoneA condenser microphone simulation for determining the sensitivity measured in dB (relative to 1V/Pa). The multiphysics system involves thermoacoustics, electrostatics, an electrical circuit, and a deforming mesh. This visualization shows the sound pressure level in the device as well as the membrane deformation.

Titanium Speaker ConeThis titanium speaker cone surrounded by air and set in an infinite baffle showcases the new acoustic-shell interaction user interface for solving acoustic pressure in air and structural deformations in a shell. The structural vibrations automatically act as a sound source and the pressure force is coupled back to act on the shell. Applications for this type of simulation range from speakers to ship acoustics.

Diesel Particulate FilterA diesel particulate filter (DPF) is designed to remove soot (diesel particles) from the exhaust of diesel engine vehicles. Although a DPF's main function is filtering exhaust flow, it is made with porous materials that have acoustic damping properties that can affect the muffler system. These effects, in turn, can affect the performance of other components in the vehicle. In this poroelastic wave simulation, the transmission loss in dB is computed for the range 0-2000 Hz.
