Study subjects

Electroacoustics

Laboratory: SPLab
Garant: Ing. Jiří Schimmel, Ph.D.
Area of study: Human-machine interaction, Acoustic signal processing
Level and semester: Bachelor's studies, 4th semester

Goal

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.

Learning outcomes and competences

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.
