Evaluation of Noise Exposure in Gypsum Plant in Terms of Work Safety
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.
