The vibro-acoustic FE simulation involves the coupling of the mechanical structure with the fluid in which the sound pressure waves propagate.
Eidos Engineering, with its simulation tools, is able to predict the vibro-acoustic behavior of a system during the early development phase.

Finite element simulation of vibro-acoustic behavior of an appliance in a closed room.

In the picture at side, the vibration map of the walls of the appliance.

Below, the maps of acoustic pressure inside the room at two different frequencies.

Acoustics:

• Vibro-acoustic simulation
• Computing of sound insulation of a panel
• Acoustic intensity maps
