Anotation:

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.
