Assessment of the Acoustic Microclimate in the Zone of the Switch Unit in the Heavy Roller Conveyor Line – Case Study

The sign of the so-called human engineering policy introduced in the industry is decreasing the occupational hazards and making the workplaces as comfortable as possible. That tendency finds expression in the tightened industrial safety-code. Among the annoying /damaging physical factors occurred in the workplace environment, the noise is of especially great importance. One of the most active noise sources in the warehouse systems are the conveyor lines for continuous transport of palletized load units. The measurement results of the main acoustic quantities in the zone of the heavy switch unit in the roller conveyor line are presented. The noise hazards, the speech intelligibility and the perception of the warning acoustic signal in this area are determined.
