Lecture "Fundamentals of Acoustics"

Basic Information

Lecturers:   Jan Abshagen  (lecture) and Thorben Kaak (exercise)
Room:   see Univis for details
Language:   English
Term:   Winter term
Target group:   Students in electrical engineering
Prerequisites:   Previous knowledge about digital signal processing and linear systems.
Contents:  

During the lecture and the exercises basic knowledge about the principles of sound and vibrations and their applications in the field of underwater acoustics should be acquired. Students should learn about the physical and technical aspects of noise generation, noise measurements, and noise reduction in underwater environments. By means of comparison the students should recognize the differences between waterborne and airborne sound. Elementary methods and techniques of underwater sound measurements should also be understood by the listeners of the lecture.
