Civic amenities building
Baroň, Alexandr ; Pilný, Ondřej (referee) ; Berková, Petra (advisor)
The first part of this diploma thesis is to design an energy-efficient hotel with restaurant and car parking. The second part is also to create an assessment of the energy performance of the building and usage of energy from renewable sources. Hotel is designed with the idea of „smart buildings“ which means, that all the technological background is controlled by the main computer, which also harvests data to achieve a minimum energy use and financial demand and maximum comfort and safety at the same time by controlling the connected technology. By placing on a sloped terrain in the center of Brno, the basement floor can be used as car parking. The roof of this building is flat, green, with modifications for placing solar panels, whose design is part of this work. The third part of this diploma thesis is the spatial acoustics of the conference room on the first ground floor.

Reconstruction of the multifunctional room music school with an emphasis on acoustics
Sehnal, František ; Donaťák, Vladislav (referee) ; Donaťáková, Dagmar (advisor)
The aim of the diploma thesis was to design the reconstruction of the music hall in the existing building of the private music school D-Music. The building is located in Kromeriz, cadastral area Kromeriz. I emphasize the design from the perspective of acoustics. The thesis also evaluated the noise load from the adjacent road II. class, for design hole fillings. It is a five-storey building with one underground and four above-ground floors. The music hall is located on the first floor and is designed multifunctionaly - for music with mobile acoustic absorbers for speech.

Design and Realization of Acoustic Treatments of Acouctic Space for Musical Production
Skvaril, Šimon ; Říha, Kamil (referee) ; Schimmel, Jiří (advisor)
Subject of this thesis are acoustical properties of space which is used for musical production and reproduction. It covers procedures, which are used for finding out acoustical parameters of chosen space, including virtual modeling and software simulation. Next, there are calculations and design of acoustical elements, which should help to improve quality of music listening. At the end those elements are created and applicated with their functionality verified by measuring acoustical properties

Room Acoustics Simulation Application
Krbila, Martin ; Szőke, Igor (referee) ; Mošner, Ladislav (advisor)
This thesis deals with simulation of room acoustics. The first part of this thesis contains theoretical description of existing aproaches to simulation of acoustics and compares their strenghts and weaknesses. For the purpose of impulse response calculation, several geometrical methods were implemented, such as ray tracing, image method and a combination of those two methods. Application with graphical and text user interface was created, to allow simulation of rooms with arbitrary geometry. The application also allows user to obtain impulse response in a form of a sound file, to visualize the results and the process of sound simulation and to perform auralization. The results of the simulation were compared with measured impulse responses of real rooms. The comparison showed, that the hybrid method is the most accurate of methods implemented in this thesis, and that the best results are achieved by simulation of empty medium-sized or large rooms.

Recording Studio with Accommodation in Proseč
Jun, David ; Remeš, Josef (referee) ; Kalousek, Lubor (advisor)
The thesis deals with designing a recording studio with accommodation. The object is drafted as a three-level construction built on a slightly sloping terrain. The purpose of the studio is to record primarily artificial chamber music and the accommodation space ought to be provided preferentially to the musicians involved. Attention is paid especially to the space layout and structure of the recording studio. The thesis is based on foreign literature and focuses on unique approaches to designs of absorbent and diffuse elements.

Acoustical room impulse response database with parametrization of subsequent reverberation
Šiška, Jakub ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
Theoretical part of this bachelor’s thesis discusses description of impulse response, echogram, various methods of impulse response measurement and their comparison. Next part includes describing objective acoustical parameters, remaining energy analysis and its frequency dependent visualization by energy decay relief. Furthermore, existing databases of impulse responses are documented. The practical part consists of realization of own database of impulse responses and various graphical visualizations computed from these impulse responses. In the next part, algorithm for energy decay relief parameterization and modeling of impulse responses is described and realized in Matlab software. In the last part, a listening test is performed to verify impulse response modeling.

Analysis of Acoustic Space Objective Quality Criteria of Orlí Street Theatre
Bělunek, Adam ; Frenštátský, Petr (referee) ; Schimmel, Jiří (advisor)
The core of the theoretical part of this work lies in a summary of basic laws and principles of a room acoustics, behavior of sound waves, reverberation time, sound absorption, impulse response and methods of measurement. Furthermore, the work describe and define some of the objective quality criteria of concert halls we know. We can find basic time criteria (e.g. reverberation time, early decay time, bass ratio, high frequency ratio…) and energy criteria (e.g. objective clarity, strenght of arriving energy…) etc.. The main focus is on a script, that is programmed in Matlab. It handles calculation of some objective quality criteria of concert halls. The function of the program is described. There are some trial calculation, that are evaluated. Functionality is demonstrated on some impulse responses, that were measured in hall of a theatre Divadlo na Orlí. The positions of microphones were different and also the configuration of acoustics elements in this hall was changing. Results were compared and commented. Another part of this work are scripts for calculations of impulse response and frequency response.

The church in Lesna
Pospíšil, Vojtěch ; Berka, Pavel (referee) ; Berková, Petra (advisor)
This theoretical diploma thesis deals with room acoustics and the closely related issue of reverberation. Part of the work is a drafting of acoustic modifications of the church based on manual calculation, which was further modified in a specialized software Odeon Room Acoustics Program. For the surrounding buildings of the church was created a study of the noise in a program Hluk+ in order to assess what will be the noise impact of this new building on its surroundings. On the basis of specialization was created several proposals for the design of the church. The approximate proposal of the double-plated dome, a system of drainage of the coupling neck, and the ways the anchor of the hard large-format window glazing. The result of the work is suitable design of acoustic adjustments and improvement of the listening qualities for the future construction of this church.

Kišac, Matej ; Kurc, David (referee) ; Orlovský, Kristián (advisor)
This thesis deals with the acoustics of enclosed spaces and psychoacoustics. The first part is based on theoretical information about main structure of room acoustics and we concentrate on impulse response of the room. Next part is directed to the description of connection between basic parameters and room impulse response and their properties. These properties may be evaluated by means of methods processed in the third portion. Then we briefly focus on the panning process. The following section offers the knowledge acquired in the simulations of selected parameters(spacious impression, clarity, intimacy). In conclusion, it contains a solution of algorithm to simplify the generation of impulse response and comparison of objective parameters of my algorithm and the image method.
