Positioning system for noise measuring microphones
Pulec, Václav ; Březina, Lukáš (referee) ; Singule, Vladislav (advisor)
The thesis deal with programing of algorithm for creating measuring box composed of measuring points. Coordinates of these points will be used for planing trajectory of the robot’s effector. It describes construction of structural model in Solid Works and calculate dynamic model by matrix formalism in MATLAB. In conslusion dynamic model of positioning system is used for the choice of appropriate motors.

Software for Processing of Sound Level Meter Data
Kříž, Petr ; Schimmel, Jiří (referee) ; Kurc, David (advisor)
This thesis deals with the measurement and evaluation of noise. Thesis summarizes the basic concepts of acoustics and describes methods of measurement and evaluation of noise, focusing on measurement uncertainty. Part of this work is the implementation of software for processing of sound level meter data NTi XL2 in Matlab including practical examples of its use.

Spectral analyse of sound in space acoustics
Port, Martin ; Bereznanin, Martin (referee) ; Rozman, Jiří (advisor)
This thesis is an introduction to the problems of acoustics and is focused on the variables describing the noise. The methodology for measuring noise in relation with valid hygiene standards is analyzed in next section. The noise levels at work required by government regulation no. 148/2006 are summarized in a subsequent charter. The next section is an introduction to the analyzer PULSE 3560B from Brüel & Kjar. This work describes a software called Labshop, which is designed to analyze noise and vibrations. It also describes the most common features Acoustilyzer NTI AL1. The practical part was to measure the reverberation, noise, frequency spectrum and plott the distribution of noise with noise maps of various auditoriums.

Loudness Index Measuring
Hloušek, Pavel ; Mach, Václav (referee) ; Kurc, David (advisor)
This thesis deals with noise measuring. There are described methods of measurement and evaluation of noise, focusing on Steven’s loudness calculation method. Basic concepts of acoustics are provided in the first part. There are also mentions measurement of noise using microphones and sound level meter. The second part is focused on the practical solution of thesis. In which it is made measurement of noise using sound level meter NTi Acoustilizer and implementation of the graphical user interface for calculation of the Steven’s loudness index in Matlab.

The noise map in GIS
Rodryč, Filip ; Čech, Petr (referee) ; Čížek, Martin (advisor)
This work consist theoretical basis and practical examination of system ArcView. There are analyzing quantity, which describing noise and in brief acquaint with methodology of noise measuring. Contains limits of noise in working environment laid directions government’s no. 148/2006. Further that mull over method of noise measuring in working environment. There is described Geographic Information System and his parts. This work mull over architecture of software ArcView and his superstructures, which measure up process of geographical data and analyze data nearly connected with region of life environment. There are described measuring instruments Acoustylizer NTI AL1 and PULSE 3560B, which are intended for measuring and analyzing of noise. In the end there are introduced results of measurement and noise maps for given situation.
