Application of sound-absorbing material around a chassis dynamometer
Kašpárek, Jan ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This diploma thesis deals with determination of an absorption properties of samples made of specific materials. The aim is to determine these properties with the help of impedance tube and anechoic chamber. These experiments are later simulated with ANSYS software. Results of both methods are compared and reasons of differences are studied.
"Music Scene" - a concert hall for the city of Brno
Zatloukalová, Veronika ; Marek, Jiří (referee) ; Šindlar, Jiljí (advisor)
The subject of this thesis is the design concept of the architectural study of a concert hall, namely the proposal for a "MUSIC SCENE" - the concert hall for the city of Brno. As part of this study is therefore designed a hall for 591 visitors. Hall enables performances to 90-member orchestra or choir. The solution is also operating and maintenance facilities necessary facilities like auditorium. The main emphasis was put on the acoustic solution, then the overall transparency in the operation of the building and the continuity of the building and the surrounding development mainly to the existing communication system that tries to respect.
Ventilation of a multifunctional house
Husák, Martin ; Rubina, Aleš (referee) ; Rubinová, Olga (advisor)
The bachelor's thesis deals with the design of ventilation equipment and air conditioning for a multifunctional building, which has 4 doctor's offices, a hairdresser, a driving school and 3 residential flats. The house is designed to meet all the necessary requirements regarding ventilation. Air handling units are designed to discharge degraded air to the exterior and bring fresh air back. Thermal comfort for the winter is ensured by radiators and in the summer by air conditioning. The theoretical part is focused on climatic conditions for the design of air conditioners, refrigeration systems and refrigerants.
Sports complex
Touš, Jakub ; Pobořil, Lukáš (referee) ; Petříček, Tomáš (advisor)
The main focus of this thesis is to design the expansion and modernization of a sport complex "U Jezu" for a sport club TJ Roztoky. This thesis is consisted of a study for a territorial agreement. In this study, there are indicated a formation of two playing fields with the artificial surfaces, beach volleyball court proposing two building objects as a base for the entire complex, which consists of garages, storages and a main building. A more detailed design was created for the main building. As the supporting structure of the object, the transverse wall system completed with outdoor columns supporting the cantilevered portion of the ceiling tiles, which are mainly unidirectionally reinforced concrete floor slabs. The supporting structure is based on the strip foundations. The designed building object has two-above ground floors and a ground floor, which will be created by embedding the building object into the hill side. The ground floor is designed for the relaxation and the leisure purposes. Moreover, there is also a technological equipment necessary for the operation of the facility. On the first above ground floor, there are designed locker rooms for athletes, a club room with a kitchen and an accommodation unit for a manager of the complex. The second floor is for the accommodation. There are designed rooms with lounge and office of the president of the sport club. Part of the second floor consists of a terrace. For the roofing, a flat roof with a single-classic sequence of layers is designed. In this thesis, the static is partially solved. Furthermore, the object is evaluated in the terms of lighting, acoustic and thermal requirements as well as requirements for the fire safety of buildings.
Passenger Car Internal Acoustics
Prokšová, Lucie ; Řehák, Kamil (referee) ; Novotný, Pavel (advisor)
The thesis is focused on the analysis of the acoustic properties of the interior of the passenger car by using the finite element method. Part of the work is an analysis of the excitation effects of individual vibration sources and the evaluation of the response in the interior of the cabin with a focus on the passengers of the vehicle and also solving the problem of the design of structural modifications in order to reduce the noise inside the cabin.
Air conditioning of the cinema
Czempka, David ; Rubinová, Olga (referee) ; Blasinski, Petr (advisor)
The aim of this bachelor thesis was to design air-conditioning systems in the selected cinema equipped with a spacious foyer with bar, cinema hall with technical facilities, recording studio and secondary spaces. Systems are designed to meet hygienic, operational and safety requirements and to create an optimal indoor microclimate for people. The air-conditioning systems provide distribution of fresh air and extract of exhaust air, covering the heat loss in winter and heat gains in summer, and in selected spaces also humidification in the winter season. In the theoretical part of the thesis, I focused on the basic acoustic quantities and spatial acoustics.
Analysis of Technical Requirements for Buildings with Focus on Building Physics
Gábrová, Lenka ; Superatová, Alena (referee) ; Čupr, Karel (advisor)
The Thesis "Analysis of Technical Requirements for Buildings with focus on Building Physics" deals with the solution of masonry and monolithic residential buildings in terms of building physic requirements primarily listed in Decree No.268/2009 Coll and in Czech technical standards.
Application for Measurement of Room Impulse Responses
Vrbík, Matouš ; Balík, Miroslav (referee) ; Schimmel, Jiří (advisor)
This paper studies problematics of room impulse response measuring. Signals appropriate for measuring are mentioned, with emphasis on stepped sine signal (sweep) and MLS signals. Measuring methods suitable for particular signals are introduced. Another parameter characterizing room qualities is reverberation time. Theoretical and practical methods for determination of this parameter are described. First part of this thesis offers solution in MATLAB environment. Functions for generating measuring signals and for subsequent processing of measured data were created. In second part of this thesis, methods were implemented in C++ language and standalone application, which uses ASIO technology, was created.
Mechanical waves of air particles set in motion by a vibrating body
Coufalová, Kristýna ; Suchánek, Jiří (referee) ; Klodová, Lenka (advisor)
The work deals with the sound in its various forms outside the music scene in connection with fine arts. Experimentally modulates different positions between visual and audio elements. Do the musical components of shows and exhibitions only serve to manipulate emotions, or are they original autonomic works? The artistic result will be the creation of an experimental situation of direct confrontation of sound with live action. The work was significantly affected by the coronavirus pandemic, so it deals more specifically with sound/music in the virtual space and the issue of their transmission.
Water level measurement
Seifert, Jiří ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
This thesis is dealt with measurement of water level. Measurement is palced in the concrete container under the ground. It was choosen an ultrasonic sensor as an optimal result. The sensor is placed in the safety container IP 65 and it is placed outside into container. The part of water level measurement is the system of the autocalibration. The signal of the sensor is evaluated by ARM microcontroler ESP8266EX. Calculated water level is broadcasted by WiFi modul to server.
