| Abstract | Background: Noise-Induced Hearing Loss (NIHL) is a preventable occupational health problem, which is considered among the 10 major work-related illnesses. According to the World Health Organization, repair of noise damage around the world costs four million dollars. Objective: The aim of this study was to determine noise-induced hearing loss in a number of workers of the Kaviyan Steel Industry. Methods: In this descriptive-analytical study being of cross-sectional type, hearing status of 34 male workers was investigated. In the present study, workers were divided to 3 occupational groups; mechanics, turner and millers, and welders, and to determine a more exact noise exposure level based on network methodology, dosimeter was done using a TES 1358 audiometer for each group. Statistical analysis was performed with the SPSS 16 statistical software using correlations, Analysis of Variance (ANOVA) and independent-samples t test. Results: The average age and work experience of the subjects was 36.58 ± 7.48 and 11.11 ± 6.8 years, respectively. No significant relationship was observed between sound pressure level and work experience with hearing loss (P > 0.05), yet a significant relationship was found between the decline in hearing threshold in 3000 Hz, 4000 Hz, and 6000 Hz frequencies in the left ear and a frequency of 8000 Hz in the right ear and work experience (P ≤ 0.05). The relationship between age and Noise-Induced Hearing Loss (NIHL) was significant (P ≤ 0.05). Conclusion: The results showed that even in a situations where people are imposed to lower levels of noise exposure standards, increasing working experience and age may cause hearing loss. | en |
