Application of Acoustic Camera in Automotive Industry
Zicha, Marek ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
This bachelor´s thesis “Application of Acoustic Camera in Automotive Industry” is focused on description of parts of the camera, algorithms for signal evaluation and the range of appli-cations in the automotive industry. They are also important acoustic quantities discussed and they are given sound fields in which the measurement is carried out.

Noise impact of combustion engine exhaust systems
Ptáček, Petr ; Knotek, Jiří (referee) ; Zubík, Martin (advisor)
This bachelor’s thesis is focused on creating a research study about noise of combustion engine exhaust systems. Introducing of this work coves all parts of common exhaust systems while mostly focused on silencers. It further describes several methods of measuring the noise established by legislation and at its end it deals with a noise impact of exhaust system treatments.

Low noise pavement surfaces
Zítka, Patrik ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
This bachelor´s thesis focuses on the use of low-noise road surfaces, due to a constant increase of traffic noise nowadays. Within this work different types of roadways are analyzed and their advantages and disadvantages are shown. Additionally, the basic measuring methods of the traffic noise are described and summarized. Finally the procedures and results of the measurements on noise emissions on low-noise surface VIAPHONE® are discussed.

Noise in poultry breeding.
STLUKA, Petr
The primary objective of this thesis is measure noise levels in appropriately selected poultry locations. Specifically, breeding hens, which are laying and kept in battery cages three-storey vertical. A subsequent graphical evaluation of measured and calculated values and evaluate the results of the applicable standards and sanitary regulations. In case of exceeding the permissible limits of health is also necessary to propose desirable precautions to improve situation. Secondary objectives are characteristics of poultry, a description object's structural and design and its technological equipment.

Noise burden on a farms with livestock caused by transport operations.
ŠÁLEK, Tomáš
The objective of this thesis - "Noise burden on a farms with livestock caused by transport operations" is to measure and evaluate the level of noise pollution at Dvorak´s family farm in Olesnice. The results of the measurements are organised in the tables and trending graphs. The relationship is determined by the equivalent noise level which is compared with the legislative and health standards.

Noise mapping in livestock buildings for cattle.
MATĚJŮ, Aleš
The content of this work is to describe the structural characteristics of the objects and characteristics of production technologies. The main objective is to measure noise levels in selected buildings on their land borders. Measurements were stables for breeding heifers and calves. Furthermore, to ensure data from these measurements and their evaluation.

Noise Pollution of the Urban Area Caused by a Dairy Farm
BEHENSKÝ, Luboš
The aim of the work is to determine noise pollution of the urban area caused by a dairy farm in Tajanov. Three receiver locations that were chosen are located on the urban area border at which are crucial for the spreading of noise into this observed area. Nine time intervals were recorded in each receiver location. The length of each time interval was one hour. Equivalent continuous sound pressure levels were quantified for each day and night reference time interval. The levels were compared with the local noise law limits and the share of the dairy farm on the total amount of noise that has been identified.

Noise measurements in the tourism sector in the selected location.
SUKDOL, Petr
The aim of the work is to determine the noise pollution of the weekend house area around Dehtář. Receiver locations were chosen to find out noise levels in places with the highest intensity of human activity and at each observed source of noise. Noise levels were recorded in four seasons of the year. The equivalent continuous sound pressure levels were quantified. and compared with local noise law limits.

Monitoring of noise nuisance in the house for livestock breeding cows.
SVOBODA, Richard
This thesis with theme "Monitoring of noise nuisance in the house for livestock breeding cows'' is designed to evaluate the noise pollution of animals, noise pollution of service of milking equipment and noise pollution which acts on surroundings of barn and milking parlor. Results are compiled in tables and graphs and equivalent noise level is determined by a formula . Equivalent noise level is compared with the legislative and hygiene standards. In case of exceeding the standards are designed solutions

Farms for fattening pigs in terms of noise emitted into the environment.
PAČKA, Jiří
Protecting the environment is one of the most important tasks of the late twentieth and early twenty-first century. Noise is in addition to much more tangible pollution of air and water also one of the environmental hazard. Usage of mechanization at the pig breeding causes noise pollution so the main task of this bachelor thesis was to measure the spread of noise from the near stalls . Measure values and compare them with the prevailing regulatory and health standards and than use formulas to determine minimum, maximum and equivalent sound levels. Then these measured values evaluate and determine whether or not it exceed the maximum noise levels. In the case when standards are exceeded, design measures to reduce noise.
