Course developer

Course abstract

In the course project, students develop a noise map of course projects with a sound insulation calculation of the building's enclosing structures for the residential building. Period considered - day, evening, night. Students acquire knowledge of technical acoustics and vacuum, forecasting noise distribution in buildings and environment.

Learning outcomes and their assessment

After course studies, the student will have knowledge of sound processes in different environments (course project); skills for the performance of vacuum calculations in indoor acoustics, sound insulation and environmental acoustics (course project);

Course Content(Calendar)

1. The preparation of raw data;
2. Acoustics, parameters, setting them up. Reverberation, sound 3-D, articulation;
3. Sound design, computer modelling, calculation and measurement of rooms;
4. Insulation of the sounds of the structures for sound in the air, shock trowel, structural cable. LBN 016-15;
5. Noise generation mechanisms for equipment. Mechanical, hydro and aerodynamic noise.
6. Anti-noise solutions for equipment;
7. Building acoustics. The nature of the sound is in construction, noise cards.
8. Defending a course project.

Requirements for awarding credit points

A study course can be settled if a successful course project has been developed and defended.

Description of the organization and tasks of students’ independent work

Students continuously perform input data preparation, processing calculations and comparing their results to those of LBN 016-15.

Criteria for Evaluating Learning Outcomes

The assessment of the course project is posted on the basis of the use of theoretical knowledge in the development of the course project.
