Modeling Sound Field in Closed Space at Low Frequencies
 Hořák, Pavel ; Kiska, Tomáš (referee) ; Schimmel, Jiří (advisor)
This diploma thesis deals with issues of low frequency acoustics and simulation. In this work the FTDT method of simulation is used. Measuring and simulation are focused on live-sound system and are evaluated using basic sound system optimisation techniques. Main output of this work is verification of basic low-frequency acoustics principles using simulation and measuring.

Simulation of Sound Field of Sound System with Multiple Speakers in Closed Space
 Brůna, Michal ; Husník, Libor (referee) ; Schimmel, Jiří (advisor)
In this thesis basic principles of sound system design are presented. A software simulation in Matlab is written for prediction of sound field with sources of real directivity in both freefield and in a closed room using velocity potential. Reflections are simulated using mirror sources of first and second order. Frequency dependent sound absorption coefficients are implemented in the simulation. There is a GUI designed to operate on most common horizontal configurations. Those are then evaluated and advantages and dissadvantages are demonstrated using the simulation software.
