Course detail

Electroacoustics 2

FEKT-MPC-EL2Acad. year: 2021/2022

The course is focused on deepening theoretical knowledge in the field of sound waves, acoustic transmitters and receivers and physiological and psychological acoustics. It also deals with the basic models of electroacoustic transmitters and receivers and their parameters, principles and technologies of sound lossy coding, spatial information coding and representation of 2D and 3D sound fields. Theoretical knowledge acquired in lectures is applied in computer exercises in the Matlab environment. The course ends with the elaboration of an individual project.

Learning outcomes of the course unit

On completion of the course, students are able to:
- describe the frequency and directional characteristics of ideal sound sources,
- explain the principles of spatial and directional hearing,
- employ devices for multi-channel capture and reproduction of sound,
- describe methods of propagation of sound in an enclosed space and describe methods of simulation of the propagation,
- enumerate and explain the principles of sound field analysis methods based on perceptual and physical principles,
- explain the principle of sound field synthesis using WFS, ambisonic and VBAP,
- explain the principles of lossy compression of audio signals including compression of spatial sound formats.


The knowledge of basic physical laws is required as well as the knowledge of laws and quantities in electrical circuits, characteristics of electric circuit elements, circuit behaviour with inertia elements, periodical and non-periodical signal spectra, random variables and basic terms from the area of statistics, acoustics and electro-acoustics. Students who enrol on the course should be able to use instruments for the measurement of electrical quantities, sound recording and reproduction technology and sound level meters and have basic knowledge of Matlab.

Planned learning activities and teaching methods

Techning methods include lectures and computer laboratories. Course is taking advantage of e-learning (Moodle) system.

Assesment methods and criteria linked to learning outcomes

Evaluation of study results follow the BUT Rules for Studies and Examinations and Dean's Regulation complementing the BUT Rules for Studies and Examinations. Up to 20 points are awarded for the test in the computer exercises. Up to 20 points can be obtained for programming and defense of the individual project and it is necessary to get at least 5 points. Credit is awarded for completing all computer exercises in minimum scope and successful defense of the project. The minimum scope of elaboration of computer exercises is determined by the annually updated decree of the subject guarantor. The final written exam is evaluated with a maximum of 40 points and for its successful passing it is necessary to obtain at least 25 points. The oral part of the final exam is evaluated 20 points and for its successful passing it is necessary to obtain at least 5 points.
In the case of distance learning, tests in practice are performed remotely in e-learning and the evaluation of the subject does not change. The exam will take place in person, in justified cases remotely.
