Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline.

Assesment methods and criteria linked to learning outcomes

Participation in lectures is obligatory. Awarding a graded course-unit credit is conditioned by the attendance at lectures, at least 10 of 13. The graded course unit credit is given on the basis of the test of 6 questions.

Language of instruction


Work placements

Not applicable.


Students will gain basic knowledge on noise generation, possibilities of noise measurements and protection against noise.

Specification of controlled education, way of implementation and compensation for absences

If students attend less then 10 of 13 lectures they have to prove they have completed missed lectures.
