Synopsis:

The subject provides overview of main parts of acoustics. In first lectures there is introduction to basic types of sound fields, its solutions and properties. Next chapter deals with introduction to building and room acoustics. The second half of the course deals with introductions to physiological acoustcs, psychoacoustics, musical acoustics, hygiene legislation and ultrasound, infrasound and their measurement.
