Completion Assessment + Examination
Language of teaching English
Extent of teaching 2P+2L
The course provides fundamentals of physical acoustics and acoustic measurement, including problems of noise from technical and perceptional point of view. In the second part principles of electroacoustic and electromechanical transducers are explained along with their analysis. Principles of audio compressing systems and spatial sound processing are also treated.
Study targets
The course is aimed at fundamental knowledge in audio engineering.
