Goals and objectives
of the course in terms
of competences and skills
To acquaint students with the fundamentals of vibrations and accoustics In order to achieve this aim the following tasks should be fulfilled: 1st Analyse the fundamental relationships of the acoustics and vibrations. 2nd Teach students how to solve the task on oscillations and acoustics applying the computer programs. 3rd Improve students' knowledge of physics related to the fields of acoustics and oscillations 4th Teach students the skills required to be proficient in the assessment of the oscillations and acoustics of the machinery, construction machinery and engineering facilities.
