Introduction to Acoustic Grid Participation
Acoustic grid participation is an important diagnostic tool for understanding what area of the structure contributes significantly to the interior acoustic response.
- Structure grid participation
- Provides participations from the body structure side of the fluid-structure interface.
- Fluid grid participation
- Provides participations from the interior cavity side of the interface.
- Physical
- The body structure grids vibrate, exciting the interior cavity fluid grids, which eventually generates an acoustic response (which is typically a driver’s or passenger’s response).
