Possibilities of noise measurement on machine tools and determine their source
Malušek, Pavel ; Šubrt, Kamil (referee) ; Kroupa, Jiří (advisor)
This bachelor’s thesis deals with methods for sound source localization. It also analyzes types of microphones which are used for this purpose. There are detailed described the parameters of the microphones at first, principles of every method and their application in practice then. The aim of this thesis is application of these methods in determining the sound sources on machine tools and evaluation the advantages of individual methods for the specific purpose.

Design of sound reinforcement system
Košarišťan, Miroslav ; Hruboš, Zdeněk (referee) ; Brančík, Lubomír (advisor)
This Master´s thesis deals with sound apparatus. The first part is a theoretical explanation of the main part of the equipment, such as microphones, amplifiers, proofreaders, switches and speakers. Another section is devoted to the design itself, starting with the block diagram which is followed by the design of single important parts. These are made as PCB. For select-ed diagrams there is an example of PSpice program simulations and the measurement of important characteristics. The essential part of the work also addresses constructional pro-cessing of apparatus. At the end of this thesis some examples of the PCB are introduced.

Sound recording with a focus on education
DITRICH, Vít
This bachelor work deals with sound recording, especially with that of musical instruments. At first the physical qualities of sound, basic terms and the introduction to acoustics are explained. We will discuss sources of sound, how the sound comes up and in which way the musical instruments work. Furthermore we will solve the most used types of microphones and their correct and suitable application. We will focus on each musical instrument and on ways how to write down sound to be the best. Then we will clear up the sound processing, how the process of recording goes and its easy adjustment, which can be used in musical editors. We will finish looking at the possibilities of saving the records and which audio file formats are mainly used by musicians.
