LEARNING OUTCOMES Knowledge of foundamentals of vibroacoustics. Knowledge of numerical methods and skill of solving structural and acoustic coupling problems. Skill to design vibration and noise control systems TESTING METHODS Verification of knowledge of the foundamental laws that govern the vibroacoustics of structures; Verification of the ability to mathematically model the vibroacoustics characteristics of a mechanical systems; verifying the knowledge of methods and devices to reduce and control vibration and noise. EVALUATION TOOLS The oral exam aims to test the student's ability to expose any topic covered in the course and to support an argument EVALUATION CRITERIA For each topic (in thirtieths rating): Minimum knowledge (rated between 18 and 20); Average knowledge (21-23); sufficient ability to apply the knowledge in a sufficient manner (24-25); good ability to apply knowledge (27-28); excellent ability to apply knowledge with good communication skills and critical thinking (29/30 cum laude).

The course consists of lectures and practical exercises.
