Noise Analysis of Audio Signals
Kabarová, Anísa ; Mach, Václav (referee) ; Schimmel, Jiří (advisor)
The theoretical part of this work deals with the basics of acoustics, noise measurement and statistical noise level analysis. The application part focuses on the implementation of the frequency and time weighting according to the technical standard IEC 61672 and the statistical noise level analysis in MATLAB programming environment. Finally the reliability of the application is tested on real data and the results are compared to those measured by a digital Sound Level Meter.

Noise level in the surroundings of the broiler farms.
TŮMA, Marek
In my bachelor thesis I deal with the issues of the noise level in the surroundings of the broiler farms. The main purpose of this thesis is the measure of the level noise in different phases of the rearing of broilers. The measured values were used to compute the equivalent sound level of acoustic pressure. The result of this computation was compared with the current lawful legislative of the Government of the Czech Republic. The outcome of this bachelor thesis is the ascertainment if the operation of this farm is not polluting its surroundings by the noise and if there are no overrun of the hygienic regulations.
