title: [Physiological and hygienic evaluation of combined effects of vibration, noise and dynamic physical load in tea plant-picking machine operators].
abstract: The article deals with complex influences of local vibration, noise and physical overload in ACHR-330 tea-plucking machine operators. 3 sets of experiments included measurements of the vibration and noise levels caused by the machine, and involved 5 volunteers twice in each set of the experiments. The physiological study results confirmed the fact that the occupational conditions caused considerable shifts in vibration sensitivity and markedly influenced the peripheral vessels. Through a set of regression equations it was proved that local vibration and noise were mostly responsible for the functional shifts.
