Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

To receive a course-unit credit, a student has to attend all laboratory measurements and to hand over the reports. The exam has 2 parts: oral and written (theory and a solution of a problem).

Language of instruction


Work placements

Not applicable.


The aim of the course is to make students acquainted with problems caused by noise and vibrations so that they will be able to monitor the sound fields and vibrations, to measure relevant physical quantities and apply theoretical laws for their reduction. Acquiring basic knowledge about standards and regulation limits.

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

A teacher checks the attendance in labs stated in the timetable. The form and the date of the compensation of missed lessons are specified by the teacher.
