Optimalization of Audio Reproduction Chain for Hearing Tests
Halaš, Rostislav ; Schimmel, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This project describes basic steps leading to the solution of a problem associated with a poor quality of played recordings in the listening room of the Škoda Auto co. . Firstly, the main technical parameters of the reproduction chain elements are resumed. Secondly, the basics of the room acoustics, such as the distribution of the sound field in a bordered space, are explained. On the basis of theoretical relations, the main modes of a cubic room are calculated. Then, software for acoustic response computing is used to simulate various options of both room idealization (room size, absorption coefficient, etc.) and listening point location. Simulations are compared with results gained by measurement. On the basis of this measurement, the quality of acoustics of the listening room is evaluated. In next chapters, the process of the optimalization of the audio chain and setup of the Automotive Sound Quality software are summarized. To conclude, the results are assessed and further steps based on the project are proposed.

Management and production of recording of folklore ensemble
Šlechtová, Andrea ; Riedlbauch, Václav (advisor) ; Brůžek, Pavel (referee)
Main objective of this thesis is to create a sort of guide for a wide range of educated public, which would ensure covering of the financial aspects of projects focused on preserving our intangible cultural heritage. Funding such projects primarily uses subsidies such as grants, whose system is quite administratively demanding, which can be considered a negative, in various cases even demotivating factor in provision of these financial resources. The thesis should therefore provide a detailed description of practical actions set up on theoretical bases of this issue, based on the current state of our traditional culture. Due to the practical output and capabilities of individual methods of processing applications for grants is work on real project essential for model demonstration of how to ensure mentioned financial resources. In this case of the recording of Prácheň folklore music is preservation of intangible cultural heritage and its preservation in subsequent form of music media the key issue and challenge for future direction of both, regional and national culture.
