Vibro Acoustics: Projects

Vibro-Acoustics is the link between mechanical vibrations and acoustics. It permits the simulation of coupled and uncoupled structural / fluid systems. We simulate:
Teaser Vibroakustik 2022 04 06 09 24 50
  • interior noise and exterior noise
  • sound radiation: sound pressure, sound velocity, sound intensity, sound power, sound emission
  • interaction between interior acoustics, structure borne noise and airborne noise
  • durability of liquid-conducting mechanical components (cavitations)
  • acoustical transfer paths (noise path analysis)
  • sensibility of mechanical components with respect to noise excitation
For these simulations we mainly use the Vibro-Acoustics software VA One.

We provide proposals for design changes to reduce sound emission, to minimize interior or exterior noise, to avoid undesired sound paths and to reduce the mechanical stresses.
