Title

NOISE POLLUTION STATUS IN A METAL MELTING INDUSTRY AND THE MAP OF ITS ISOSONIC CURVE

Pages

  46-50

Abstract

 Background: Steel industry is one of the most important industries of each country and NOISE POLLUTION is one of the very annoying factors in this industry that causes various diseases; above all, the damage to the auditory system of the work force is high. Therefore, the assessment of NOISE POLLUTION and the identification of the sources and causes of its creation are inevitable for controlling and teaching the prevention programs and hearing protection.Objectives: This study aimed to draw the noise map of ISOSONIC CURVEs and assess the NOISE POLLUTION using Surfer modeling software.Materials and Methods: In the present study, first, preliminary maps and stationing were drawn, and then, the measurement of the sound pressure level and the octave band analysis were performed by a noise measurement device called Casella-CEL 445; then, after recording the data in software of Surfer version 8, they were used for drawing the ISOSONIC CURVEs.Results: The results of the peripheral measurements showed that the maximum sound pressure of level 109 dBA was related to the electric arc furnace. A map of the graphic ISOSONIC CURVEs showed most of the NOISE POLLUTION in the following areas: furnace, casting, tundishes, and the cooling beds.Conclusions: According to the factory noise map, except for the control rooms with 81 dBA noise, other cases of measuring stations were higher than the standard exposure of 85 dBA noise. As a result, the implementation of control strategies, such as inspection and performance of control systems and insulation of the control room to prevent unnecessary exposure noise, are necessary.
