Analýza prostředí v chovu dojnic na vybrané farmě
DOBROVOLNÝ, Tomáš
The theoretical part of the diploma thesis focuses on sources of noise in stables for dairy farming. This issue also relates to welfare of cattle and the last subject to be dealt with can be called working environment in livestock production in terms of noise load. The practical part is focused on the description of technological equipment of the stables with a plan of the measured objects. The measurement of noise levels during technological operations with cattle was carried out at selected dairy cows at the workplaces of the Agricultural Cooperative of Velká Losenice. Then the work deals with measurement of the operator's noise load during the partial operations necessary to ensure the process of dairy cows breeding. At the end of the diploma thesis the processing of individual measurement results in individual operations in measured objects is presented and evaluation of the noise load.

Hlučnost sklízecí soupravy při lisování válcových balíků
ŠOUKAL, Jan
The diploma thesis deals with the noise level of the harvester when pressing round balers. The sound pressure levels were measured at a selected distance from the harvesting set when pressing fodder. The measurement of operator noise in the machine cab (tractor) was also measured. These measured noise values are displayed in charts. The harvesting set is evaluated for environmental noise pollution according to the characteristics of the harvested land and the working conditions of the operator.

Hluková expozice obsluhy posklizňové linky
PROKURÁT, Václav
This Bachelor's thesis focuses on noise exposure of post-harvest lines operators. The main aim of the thesis was to determine the noise pollution in the workplace. The results of the measurement were mathematically processed and subsequently compared with the current Government Regulation no. 217/2016 Coll. amending Regulation no. 272/2011 Coll. on protection of health from adverse effects of noise and vibrations. Furthermore, the thesis includes noise control measures that protect the post-harvest lines operators from unwanted noise.

Noise measurements in the specific locations of traffic-engineering measures
Smejtek, Daniel ; Lachnit, František (advisor) ; Dvořák, František (referee)
This thesis deals with measurements of noise generated by road traffic. In theoretical part is described physical essence of sound, sound spread, perception of sound by human, effects of noise on human, methods of noise reduction, sources of noise from road traffic, legislation regarding noise and traffic-engineering measures. In practical part the noise was measured. Evaluate the noise at the bus stop, different noise level on straight road and sleeping policeman and different noise level on roads with different maximum speed allowed.

Use of mowing tractors to maintain green spaces.
JANOUŠEK, Jan
This thesis deals with a noise pollution caused by mowing tractors during the maintenance of a green spaces. Mowing tractors Iseki SXG 22 and Starjet Exclusive 4x4 were chosen for used measurements. Measuring of noise pollution in surrounding areas has been done from five different distances and subsequently evalueted with current legislation.

The noise analysis of selected school objects the South University
NAVRKALOVÁ, Renáta
This thesis contains the noise analysis of inside selected objects the South University depend on environment, type of transport routes a vehicles, which moved on this routes. It concerns for example cars, trucks, busses and motorcycles. Based on measured values, there is a summary the results of noise in the individual measuring places. Afterwards, there are suggested ways of appropriate noise reduction, but in this cases only if it?s necessary. The object of this work is the pointing out potential excessive noise suggesting some possibilities of its removal at the measured places.

Analysis of transport noise device on the transport environment.
KDOLSKÝ, Tomáš
This thesis contains the noise analysis of transport vehicles as cars, trucks, cargo sets, busses and motorcycles in relation of the kind of the transport environment, but also on the character of the transport routes. There are very important factors here and namely the kind of passing vehicles, the number of passing vehicles, the speed of the vehicles, weather conditions, road surface and road condition. Following to this analysis there is a summary of the results detected, which is mainly focused on the level of noise emissions in the individual measuring places. Afterwards, there are suggested ways of appropriate noise reduction. The object of this work is the pointing out potential excessive noise suggesting some possibilities of its removal at the measured places.

A Biological Noise In The Environment of Farms Breeding Dairy Cows.
DVOŘÁK, Miroslav
In stockbreeding of farm animals implicates a noise not only an implementing and increasing mechanization, but as well as a noise incurred by animals themselves. It means a noise rising by speech of breeding animals (a biological noise). The aim of this work is measuring of this noise on a family farm in Olešnice, work it up according to appropriate standards and demonstrate the results graphically. Obtained noise rates are reviewed in term of legislative and hygienic regulations and orders.
