New Lecture - Fundamentals of Acoustics

Starting this winter term the DSS group offers a new lecture entiteled "Fundamentals of Acoustcs". The lecture is given by Dr. Jan Abshagen (see picture). It will be a 3+1 lecture which takes place once a week. The lecture will cover the following topics:

  • fundamentals of vibrations,
  • theory of sound fields,
  • sound and systems,
  • transducers,
  • sound-structure interaction,
  • ship acoustics,
  • ...
