Protection Against Noise and Vibration Course code: 180617 | 6 ECTS credits

Basic information
Level of Studies: Undergraduate applied studies
Year of Study: 2
Semester: 4
Requirements: Knowledge of basic concepts of electrical engineering and mathematics
Goal: To provide students students with the basic notions of noise and vibration problems, as well as to provide the knowledge needed for noise measurements and design of noise and vibration insulation systems.
Outcome: At the end of the course, the students will be familiar with the basic principles of measurement techniques and trained to independently solve elementary problems in the field of noise and vibration.
