Evaluation of Noise Exposure in Gypsum Plant in Terms of Work Safety
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 4
Abstract
Noise is one of the major physical risk factors for workers in the heavy industrial sector. Within the context of this study, the environments in which employees are located in a gypsum plant were determined, noise measurements were made according to the work they performed, the results were evaluated and frequency-noise relationships were revealed. According to this, while the highest noise was found in the crusher unit, administrative building personnel were exposed to the lowest level of noise. The regions exceeding the exposure limit value are packaging and stone crushing units. In the measured areas, the maximum noise levels exposed by the workers correspond to the medium frequency range and the minimum noise levels correspond to the low and high frequency ranges. The maximum noise level to which workers in all branches are exposed is in the frequency range of 250 Hz and 2500 Hz. The noise levels generated by the machines are in the wide frequency range, and the maximum sounds from the noise sources in the factory are defined as thin sound. As a result of the measurements made, it was calculated that the maximum noise levels, which are mostly exposed by the factory staff, are outside the frequency range where the human ear is most sensitive.
