Simulation of sound wave propagation in closed space, using tools of geometric acoustics
Husák, Ondřej ; Kurc, David (referee) ; Orlovský, Kristián (advisor)
The bachelor thesis focuses on a simulation of sound wave spreading in closed space using tools of geometric acoustics. It mainly concerns on comparison and using of image source method, Ray-Tracing Method, and Beam-Tracing for counting of sound waves rebounds in close environment without obstacles. A big part of the thesis is measured by algorithms of image source method and Ray-Tracing Method. It´s realized in Matlab software. The results are compared on based of executed simulations.
Simulations of auditory space and azimuth&distance of sound source, for multichannel sound systems
Orlovský, Kristián ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
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 (referee) ; Balík, Miroslav (advisor)
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.
