Improving the functioning of the "man-machine" system in agriculture requires an integrated approach to determining the influence of factors in the working environment, rationing their combined effect on the body of machine operators, taking into account the nature of the work performed.
The purpose of the study is to clarify the hygienic standards for noise, general vibration and various intensity of the work performed with their combined effect on the body of machine operators. The studies were carried out in accordance with the principles of the mathematical theory of experiment - according to the scheme of a full three-factor experiment [2, 3]. Men aged 22-55 were under observation.
It was revealed that the combined effect of general vibration, noise and labor intensity on the human body is additive. Labor intensity should be regarded as a factor aggravating the adverse effects of vibration and noise, and taken into account in their hygienic regulation.
It is necessary to reduce the currently operating vibration and noise remote controls for tractors and self-propelled machines when they operate at high speeds: for general vertical vibration - by 6 dB, noise - by 8 dB when performing work of IV category of tension.
