Establishment of database of musical instruments recordings
Lavický, Vojtěch ; Mácha, Tomáš (referee) ; Rášo, Ondřej (advisor)
In this Bachelor thesis you can find created database of musical instruments. Recordings are descripted by it's waveforms and sectrograms. It may serve for example for removing noise from signal. A general data of instruments are descripted here. Human earing and his perception of sound is discuss here. There are also included parameters of sound itself and theory of calculations. Frequency and dynamic range are written to every instrument in database. These are consequently range by its size. As a part of the thesis is program with graphical user interface. The program include all the recordings from database and is open to any other recordings.

Rizikové faktory v kabině sklízecích mlátiček
ŠTEMBERK, Martin
The diploma thesis is focused on harvesting threshers in terms of noise, dust and temperature in the cab. The work is divided into two parts, theoretical and practical. In the theoretical part there are basic data and concepts of harvesters, acoustic materials and health protection at work in agriculture. In the practical part itself was performed measurement of noise, dust, temperature and humidity in the cabin cabin cabinet. Measurements took place on land of agricultural cooperatives and private owners. Based on the measured values, an overview of the parameters of individual machines was created.

Hlučnost výrobních strojů ve vybraném podniku
VOJTA, Jiří
The diploma thesis deals with noise measurement. The theoretical part contains the knowledge gained by studying literature. I have described acoustics, sound and noise, noise and health and legislative contexts as well as noise reduction methods. The practical part contains information about the company and individual machinery, the results of measurements and their evaluation according to valid legislation. I have suggested appropriate measures to reduce the noise burden on operators.

Sklízecí mlátičky z hlediska hlučnosti a prašnosti
LÍKAŘ, Ondřej
The thesis is focused on the combine harvester in terms of noise and dust in the cabin, but also outside. The literature search is the basic data and concepts from areas combine harvesters, noise and dust. The actual measurements were carried out on the land at the four farmers. Measured the machines were different dates of manufacture. These are machines Fortschritt E 512 (1983), Fortschritt E 514 (1989), IH 2188 (1998) and Claas Avero 240 (2011). The results of measurement were graphically displayed and compared each other. The measured values were compared with the current legislation. These measurements showed that the noise does not just limit oldest machine. Dustiness been in this job for guidance only. Thanks dust measurements but we get a more complete view of the work environment in which the operator is exposed.

Noise pollution on the farm for breeding goats and neighborhood.
TÁCHA, Lukáš
The bachelor thesis is aimed at assessing the farm for breeding goats in terms of noise level in the neighborhood. The main objective was to measure the noise during the working operation at different places of the selected object, to process the collected data, to calculate the equivalent noise level and then evaluate the results of the work. On the basis of measured and assessed values is apparent that the noise pollution of the examined object has no effect on its neighborhood and therefore it is not necessary to propose any specific actions to improve the current situation.

Objects of livestock production in terms of ambient noise levels
LENC, Jan
This thesis deals with the evaluation of noise exposure in the agricultural cooperative Hosín ? Dobrejovice. The aim of this work was to measure noise levels in the dairy barn area and its surroundings, during these processes work: milking, feeding, removal of excrement, bedding etc. Measurements were carried out in summer and autumn. During the measurement noise was the largest source of agricultural equipment. The results revealed that noise pollution resulting from the operation of agricultural cooperatives Dobrejovice is fair and negative influence on noise pollution does not occur.

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.

Assessment of noise exposure at different ways of rearing water fowl.
BRAUN, Petr
This Bachelor´s work describes the evaluation of noise exposure at different ways of breeding water fowl. Breed selected for measuring the goose Czech. The aim is to measure and verify the intensity of noise arising from the farms and backyard and evaluate that noise acting on the surroundings. The basis is to implement the measurement noise level in backyard farms and are growing in a farm really out of the growing season for selected habitats and compare readings with legislative and hygiene standards. If permissible limits are exceeded measured values, it will be essential to propose the necessary restrictive measures.
