Summary
Students will learn the basic procedures of the experimental acoustics and obtained experiences can virtually test and verify on the measurements in the acoustic laboratory, i.e. semi-unechoic chamber. Selected patterns of acoustic problems the students will verifie by mathematical simulation using numerical methods.

Way of continuous check of knowledge in the course of semester
Student will elaborate several technical reports, thematically linked to
current measurement issues. The form and level of elaboration of reports
is one of the evaluated criteria for completing the course. Completion
of the course is in the form of an examination.
E-learning
Other requirements
The exam has a practical
and theoretical part. In the practical part the student solves numerical
tasks in the field of technical acoustics. Foreign students can in
individual cases complete the course individually in the form of a
semester project.
