Recording Studio with Accomodation
Fiala, Jakub ; Pilný, Ondřej (referee) ; Kalousek, Lubor (advisor)
The main aim of this master’s thesis is to design a recording studio in a place of an abandoned agricultural building in a small village called Radešín. The thesis is structured into three parts. Goal of the first part is creation of a design documentation of architectural and structural designs. The building will consist of two storeys, a cellar and a gable roof. The most used building material will be reinforced concrete. Recording studio will offer three recording rooms accompanied by a large control room. Accommodation will include five apartments for ten inhabitants and a common room with kitchen. The second part is focused on design of selected building services. The building will be equipped with an air-to-water heat pump and wood chip boiler for heating. A mechanical ventilation with heat recovery will provide fresh air. Heat pump will also work as a cooling source. Furthermore, designs of the rainwater treatment, water heating, lightning and photovoltaics on the roof are included. The third part revolves around the matter of room acoustics. It describes basic knowledge and terminology of this field, which are then used to solve reverberation. I dealt with three variants – initial state, state with additional dampening and state with additional dampening with movable acoustic panels. One calculation was made in Microsoft Excel, the other one with help of room simulation in Odeon. Finally, I compared these two methods.

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.

Design and Realization of Acoustic Adjustments of Listening Room
Vajda, Michal ; Miklánek, Štěpán (referee) ; Schimmel, Jiří (advisor)
This bachelor thesis is devoted to the design of acoustic modifications of residential space and the subsequent implementation of these modifications. Its aim is to design an optimal solution of the space for listening to music in accordance with the Czech Technical Standards. The basic parameters investigated are reverberation time and acoustic quality criteria. The thesis deals with simulation in the EASE modelling program and addresses situations before and after acoustic treatment. The following methods and procedures are used to comprehensively address the above mentioned treatments and to achieve the set objective. Furthermore, the simulation is verified with a custom calculator in Excel. After using the absorbers suitable for adjustment, the implementation with the final measurement of the reverberation time is carried out. Finally, an additional modification design is created using Helmholtz resonators. The implemented methods achieve an optimal and frequency balanced reverberation time and the room can be used as a mixing hall for multi-channel sound recording.
