Aim
The course aims to present the knowledge of industrial noise reduction and noise mapping. To prepare students to perform basic acoustic and noise protection and noise mapping design and measurement tasks in mechanical engineering practice. With the knowledge learned, students will be able to solve simple industrial noise reduction and noise mapping tasks, perform simple noise reduction and noise mapping design tasks, and be able to independently develop their acoustics knowledge to solve more complex noise mapping tasks. The knowledge of the subject complements the knowledge of the basic technical acoustics and noise reduction subject with state-o-the-art software noise mapping simulations and lays the foundation for the successful completion of the master-level acoustics subjects.

In some situations, as part of a team, the student works with fellow students to solve tasks. The student supports a systematic approach and complex thinking in their thinking. The student is critical of engineering commitments of inadequate quality.
Teaching methodology
Lectures, computational exercises, written and oral communication, IT tools and techniques, optional individual and group assignments, work organization techniques. Presentation of theory and numerical examples during the first 6 occasions of the semester, two hours of lectures per week, and writing of the exam on the material from the curriculum. Demonstration of the use of the noise mapping software during the 8th lecture. Thereafter, during 5 two-hour laboratory sessions, students solve specific noise mapping tasks with the help of a consultation teacher. During the final seminar, each student presents the results of their work in the form of a short presentation.

General rules
During the semester, the participation in the lectures, the writing of the exams, participation in the laboratory classes, the preparation of 3 individual assignments and the related simulation reports, and the holding of the oral presentation. The necessary condition for obtaining the mid-semester grade is completing the exam with at least a sufficient level, participating in the laboratory classes, and preparing the simulation reports and the oral presentation on the 3 individual assignments. The maximum score that can be obtained on the exam is 50. The sufficient level is 40% of that, 20 points. A maximum of 15 points can be awarded for the report of an individual assignment noise mapping task report, and an error-free oral presentation is worth 5 points. The sufficient level is 40% of the highest attainable score, which is 6 points for the reports and 2 points for the oral presentation.
