Abstract
Background: Noise pollution is one of the most important risk factors in industrial settings. This study aimed to assess noise exposure and noise-induced annoyance among workers of a steel factory. Methods: This cross-sectional study was conducted on 70 healthy male participants (33 office employees and 37 production line workers) in a steel plant. Results: The results showed that 24.24% of employees in office areas and 54% of blue-collar workers had high noise annoyance. Also, noise levels in two parts of steel factory and percentage of responds by participants that felt highly annoyed showed a significant relationship (P < 0.05). Feeling of discomfort was a major complaint that was stated by office employees (%59) and blue-collar workers (%38). Conclusions: The findings of this investigation have clearly revealed that employees in both parts of steel factory are annoyed by noise. A higher noise level resulted in higher noise annoyance in the exposed workers. The need for implementing noise conservation program was established.
