Abstract

The paper describes some of the possible applications of geostatistical models in the analysis of noise in the workplace. This study was conducted in an environment of technical system, the shredder of plant mass "Willibald 2800" and the combined processing machine (tractor loader shovel) manufactured by "JCB", type "4CX" which was filling the shredder with plant mass. The survey was conducted during the normal operation of machines. Measuring emitted noise levels was carried out with the device for measuring noise produced by "METREL" type
"Multinorm MI 6201 EU" with a corresponding sound transducer (microphone Class B) of the same manufacturer. The final result of the research is a model of generating two-dimensional and three dimensional maps of noise "Point Krigging" method which in an easily understood manner presents the results of noise measuring and allows experts to help you make decisions regarding safe operation. Noise maps are essential for adequate observations and monitoring of harmful effects on humans in the working environment.
