Acoustical measurent in real environment
Mach, Václav ; Mačák, Jaromír (referee) ; Míča, Ivan (advisor)
This bachelor thesis discusses the issue of acoustical measurement. There are dierent signals described, which are used for this purposes, both MLS and esweep, compared their advantages and disadvantages and made some practical demonstrations of impulse response measurement. Furthermore, the fundamentals of reberbation time measurement are described in theory. The practical part of this thesis consists of the measurement application, written in the C++ language and mainly targeted for Linux systems. Qt multiplatform toolkit has been utilized for the GUI part.

Testing of room acoustics
Toufarová, Tereza ; Špalek, Karel (referee) ; Sigmund, Milan (advisor)
This paper presents parameters of evaluation of acoustic quality of the space. It is divided into parts presenting physical principle of the origin and movement of the acoustic signal, principles of its processing with current technology and properties of the acoustic field. This is followed by an analysis of the musical part and notes on psychoacoustics. The document contains a description of relevant parameters of acoustic spaces and way in which we can reach desired results, including material analysis. The paper mainly focuses on description of relevant parameters of three acoustic spaces which were measured. The last part of the work is a program for elementary acoustical measurement, which can be provided by means of commonly accessible equipment such as a notebook or a personal computer.

Software generator of test signals for acoustic measurements
Veselá, Petra ; Schimmel, Jiří (referee) ; Frenštátský, Petr (advisor)
The aim of the thesis is to create a VST2 plug-in module capable of generating input signals for different kinds of acoustic measurements. The opening section offers a theorethical overview of various test signals, their parameters and possibilities of their use during measurement. Subsequent divisions are then introducing a description of several methods of acoustic measurements and a brief overview of a VST interface. Last chapter offers the analysis of the created signals and discussion of their potential use in practice.

Influence of Disposition of Opera Stage and Orchestra Pit on Theatre Acoustics
Berky, Martin ; Balík, Miroslav (referee) ; Schimmel, Jiří (advisor)
This semestral thesis describes messurement of reverberation time, monaural and binaural impluse response Divadlo na Orlí during positioning of sound-source in orchestra pit and on the stage. Theoretical part describes messurement of reverberation time and objectiv criteria of soundfield quality in concert and opera. The practical part describes messurement in Divadlo na Orlí and computations in program Matlab. The thesis compares results in various configuration of theratre hall and describes common advices for operas in Divadlo na Orlí.

Removal of a Known Signal from a Recording
Urbánek, Radomír ; Žmolíková, Kateřina (referee) ; Černocký, Jan (advisor)
The goal of this diploma thesis is to design and implement method for removing known signal from recorded sound. In the introductory part of the thesis are described the properties of sound and its propagation through the space, digital signal processing on the computer and the computing of the system impulse response. The sequential development of the methods leading to the removal of the known signal from the recording is described further. The following part contains a description and implementation of this method. It also describes how and at what data the method will be tested. Finally, testing is evaluated, improvements and further possible work is proposed.
