Vibro-Acoustics
VA One: Coupled FEA/SEA Training
Reference: VAO-H-A

Level: Advanced
Duration: 2 days
Audience: Engineers who wish to better understand mid-frequency problems and analyze structure-borne and air-borne noise using the Hybrid FE-SEA method.
Objectives: Understand the theory and applications of the Hybrid FE-SEA method. Carry out mid-frequency engineering design and analysis using the Hybrid FE-SEA module of VA One.
Prerequisites: Participants should be familiar with the fundamentals of acoustics and vibrations. Suggested courses: VA One: Basic SEA Training (SEA-B), VA One: FE/BEM Training (VAO-FE-B)
Description: Combining lectures, demos and practice sessions, participants acquire basic knowledge and understanding of mid-frequency and coupled FEA/SEA problems. Recent applications are reviewed and participants gain hands-on experience with the mid-frequency modules of VA One.
