Course overview

In the industry today there is a large demand for staff with good knowledge in techniques of measurement applicable to solve sound and vibration problems. The involved mix of knowledge from acoustics, mechanics and signal analysis in these techniques of measurement is a difficulty. This is a continuation of the course ETC009, Sound- & Vibration-Analysis I.The goal is to give the students a deeper knowledge on how to use applied signal analysis in order to describe vibrations in structures with experimental modal analysis. The contents of the course are; wave propagation in solid material, experimental modal analysis, use of modal models for simulating of forced vibration.
