Simulace šíření zvukové vlny v uzavřeném prostoru pomocí prostředků geometrické akustiky
Husák, Ondřej ; Kurc, David (oponent) ; Orlovský, Kristián (vedoucí práce)
Tato bakalářská práce pojednává o simulaci šíření zvukové vlny v uzavřeném prostoru pomocí prostředků geometrické akustiky. Zejména se jedná o srovnání a použití Obrazové metody, metody Ray-Tracing a metody Beam-Tracing pro výpočet odrazů zvukových vln od stěn v uzavřeném prostředí bez překážek. Velká část bakalářské práce je zaměřena na algoritmy Obrazové metody a metody Ray-Tracing, které jsou zrealizovány v prostředí Matlab, a jejich výsledky jsou srovnány na základě provedených simulací.

Simulations of auditory space and azimuth&distance of sound source, for multichannel sound systems
Orlovský, Kristián ; Schimmel, Jiří (oponent) ; Balík, Miroslav (vedoucí práce)
This thesis is aimed at simulation of auditory space. It describes the most frequently used panning method: Vector Base Amplitude Panning. Also is focused on image source method, which allows computing the parameters of direct sound wave and reflections in rectangular room. This method is compared with ray–tracing method, which is also often used. It deals with the matter of the frequency – dependent absorption of materials in reflection of the sound wave against the wall. On the basis of these information two applications were designed in MATLAB development environment. The first one allows the simulation of auditory space. The other one is the application for sound source panning by its azimuth and distance.

Sound panning in multichannel sound systems
Orlovský, Kristián ; Schimmel, Jiří (oponent) ; Balík, Miroslav (vedoucí práce)
This thesis is aimed at simulation of auditory space. The first part is based on theoretical information and explains two of the most frequently used sound panning methods: Vector Base Amplitude Panning and Ambisonics. It shows the ways for sound panning by these methods. In next step are methods compared based on theoretical information and simulations in Matlab environment and one most suitable method is chosen for using in second part. This part describes image source method which enables parameters computation of direct sound wave and optional number of early reflections in rectangular room. Also is focused on problem of frequency dependent reflections. In conclusion it offer knowledge obtained by simulation of different auditory spaces with different topology.
