Title of the thesis:
Analysis of noise in cattle farming at various technological solution of milking devices
Summary:
The dissertation thesis focuses on the evaluation of noise level in milking systems in their various technological solutions in cattle husbandry. The work deals with herringbone, tandem and side by side milking parlours, automatic milking systems and milking systems for tie-housed cows with pipeline milking, and evaluation of their noise levels, according to milker, as well as to animals (diary cows). The introductory part of the thesis is focusing on a brief overview of issues of noise, its impact on the organism of human and animals and on the issue of technologies of milking devices. In the experimental part, we are dealing with measurement, which were carried out on 20 dairy farms in Slovakia, Czech Republic and Finland. To carry out these measurements, noise analyser Brüel&Kjaer type 2270 and personal noise dosimeter 3M EG4 D were used. Measured values were processed in four chapters, such as noise comparison of individual systems in terms of noise levels, noise analysis according to selected frequencies, evaluation of noise exposure of milking parlour operators with using noise dosimeter and comparison of noise emissions of the loudest machine mechanisms in the milking systems, vacuum pumps. Measured values were compared with results of other author´s research. Values of noise exposure of workers during 8 hour working shift were calculated, ac-cording to Directive of European Parliament and Council Nr. 2003/10/EC and compared with exposure values and the noise exposure limit values given in this regulation, which is valid throughout the European Community. Various technological solutions of milking systems have been compared to each other.
Key words:
noise exposure, frequency analysis, milking devices, vacuum pump
