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.

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.

Measurement of the reverberation time
Hořák, Pavel ; Ryndová, Anna (referee) ; Jedelský, Jan (advisor)
This bachelor thesis deals with issues concerning measuring of reverberation time in closed rooms. Two evaluation methods are described in this thesis; integrated impulse response method and interrupted noise method. Data were recorded with the aid of acoustic module Photon+ and RT Pro 7.1. software. Practical part comprises implementation of evaluation programme in Matlab environment. Computation of reverberation curves is a major output of the thesis. Individual methods are compared on the basis of discovered figures.
