Background and Objective: Exposure to sound levels above the permissible occupational limits in industrial environments, in addition to causing auditory effects, can impact cognitive performance and emotional states, leading to human errors and ultimately workplace accidents. Accordingly, this study aimed to investigate the effect of noise on aggression levels among industrial workers.
Materials and Methods: This cross-sectional study was conducted on female workers employed in a polymer product manufacturing industry in Bushehr Province, Iran. A total of 161 participants were voluntarily selected through random sampling, after obtaining written informed consent. Based on their noise exposure levels, workers were divided into three groups: Group 1 (exposed to noise levels below 75 dB), Group 2 (exposed to noise levels between 75 and 85dB), and Group 3 (exposed to noise levels above 85dB). Participants completed the Buss-Perry Aggression Questionnaire. Data were analyzed using SPSS software (version 21) through one-way ANOVA, paired t-test, independent t-test, and Pearson correlation coefficient.
Results: The mean aggression scores in the groups of <75dB, 75-85dB, and >85dB were 65.24±1.29, 69.02±1.7, and 79.93±1.66, respectively. There was a statistically significant difference in terms of the level of aggression in the groups exposed to sound below 75 dB and sound between 75 and 85dB, with the group exposed to sound above 85dB (P<0.001).
Conclusion: The results of this study indicate that, despite controlling for other parameters, increased noise levels in the workplace lead to higher aggression among individuals. Aggression may be influenced by various factors, such as job dissatisfaction, family issues, heat (unfavorable weather conditions), and air pollution at the workplace. These factors, alongside noise pollution, pose health risks to workers in industrial settings, and implementing preventive programs can effectively reduce the occurrence of accidents.
