In this course you will learn how to define aero-acoustic sources (distributed dipoles, distributed quadrupoles, fan sources) as excitations in your BEM analysis.

You will also learn the usage of random acoustics, MATV sensitivity (for optimization), and Inverse Numerical Acoustics (vibration back-calculation) in various practical applications (including wind noise, turbulent noise, engine noise.).

WHO SHOULD ATTEND

This course is intended for advanced users of LMS Virtual.Lab acoustics.
