The lecture "Machine Acoustics and Dynamic Causes" is offered as an elective course for students in the master's program. In this one-semester course will be studied the question of why vibrations can occur in mechanical engineering systems and under which circumstances they are audible to humans. The focus sits on the fundamental correlations of machine acoustics, but today's controversial phenomena such as infrasound are also considered. This includes, in particular, the excitation or excitability of a system as well as the transmission and radiation of sound energy. Examples from general mechanical engineering, rail vehicle technology and wind energy are used to discuss relevant problems in the acoustic environment and to promote an understanding of the overall acoustic system. Finally, the consideration of possibilities for noise reduction aims at deepening the contents of the preceding lectures by means of a practical example.
