Purpose: This study was conducted on wage workers aged 20 or older and with a working period of 1 year or more using the 6th working environment survey conducted by the Korea Occupational Safety and Health Agency, and was studied to investigate the correlation between workplace noise and job mental factors.
Method: Statistical analysis was performed using R Studio for Windows, frequency analysis, chi-square test, and multiple logistic regression analysis were performed.
Results: A chi-square test to investigate the relationship between "population social factor", "harmful environmental factor", "work environmental factor", and "health impact indicator factor" showed a significant difference in working environment satisfaction factor, and satisfaction was higher than dissatisfaction. In the noise category, the higher the exposure, the higher the percentage of dissatisfaction with the working environment. There were significant differences in all items except noise in job stress factors, and in all items except elementary education in educational background, job stress 'being' was higher than 'none'.
As a result of multiple regression analysis, it was found that noise in the working environment satisfaction factor was severe exposure (2.227) and mild exposure (1.747) and the difference was larger as the exposure was severe, and statistically significant. There were no significant results in job stress factors.
Conclusion: Contrary to the expectation that noise factors will have a significant effect on job stress, this study found that there is a significant effect only on working environment satisfaction. Although there was no relationship with job stress, there was a significant relationship with work environment satisfaction, and there was a positive effect on work environment satisfaction 'unsatisfaction'.
It is expected that interest in noise factors that have a significant effect on the working environment will increase through the results of this study and previous studies.
