| Abstract: | Despite the advantages associated to mechanization, the noise generated by machines and equipment may cause discomfort to workers, possibly even jeopardizing their health. Thus, this paper is aimed at assessing the noise level of two agricultural machines (hedge trimmer and backpack blower) and to characterize them spatially by means of geostatistics. Data collection was performed at the average height of the worker’s ear and within an equidistant circumference of 1 m up to the limit of a sample area with a radius of 22 m. The data fitted models of gaussian and spherical semivariograms for the evaluated equipment, a hedge trimmer and backpack blower, respectively. The spatial noise analysis allows for the definition of a work regime and the need for the use of personal protection equipment. |
