Overview of basic acoustic and mechanical quantities and their units. Knowledge of hearing physiology and psychoacoustical phenomena including spatial hearing. Knowledge of the principles, characteristics and applications of particular types of transducer, knowledge of the loudspeaker systems design. Knowledge of the noise measuring and identification instruments, basic measuring instruments for the electroacoustical measurement and its application. Knowledge of the principles and types of surround sound systems and methods of the multichannel sound pickup.

The basic knowledge on the level of following compulsory subjects from previous semesters of the study area is required: Signals and systems analysis, Measurement in electroengineering, and Electrical Engineering.

Not applicable.

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.
- Lectures provide the explanation of basic principles, subject methodology, examples of problems and their solutions.
- Laboratory exercises support practical acquiring of themes presented at lectures. Active participation of students is needed.
Participation at lectures is recommended. Participation at other ways of instruction is checked.

Evaluation of study results follows Rules for Studies and Examinations of BUT and Dean's Regulation to the Rules for Studies and Examinations of BUT. Up to 20 points is given for test from theoretical knowledge in the laboratory exercises. Up to 20 points is given for correct results and elaboration of all laboratory exercises and completive questions. The minimal scale of elaboration of particular laboratory exercises is specified by a regulation issued by the guarantee of the course and updated for every academic year. Up to 60 points is given for the final written examination.

2. Energy transmitted by sound, sound spectrum, Doppler principle, acoustic impedance.
3. Physiological acoustics, subjective and objective characteristics of sound, sound masking and its utilization in audio compression algorithms.
4. Directional and spatial hearing, 3D room simulation using headphones and loudspeakers.
5. Noise and its measurement, basic measuring instruments for electroacoustic measurement and their application.
6. Room acoustics, acoustic wave trajectory, room impulse response, acoustic materials.
7. Electromechanical and electroacoustic analogy.
8. Types and operation principles of electroacoustic transducers.
9. Classical and combined types of microphones, practical design and measurement of characteristics.
10. Loudspeakers and headphones, acoustic impedance and distortion, mechanical design, horn-loaded loudspeakers.
11. Loudspeaker systems, types of loudspeaker enclosures, design and construction of loudspeaker enclosures and crossovers, acoustic lenses.

Not applicable.

The aim of the course is to make students familiar with the chain of acoustic signal processing from their origination through their transformation to the electric signal and back to acoustic signal up to the listener's final perception.

It is mandatory to pass all laboratory exercises in regular or alternative terms to complete the course. Other forms of the checked instructions are specified by a regulation issued by the guarantee of the course and updated for every academic year.
