Impact of Airport Environmental Noise on the Health and Performance of Ground Staff

Background Occupational noise in airport environments poses a significant health risk to ground staff, with potential impacts on both physical and psychological well-being. This study investigates noise exposure levels among airport personnel and assesses correlations between health symptoms and job performance. Methods A cross-sectional analytical study was conducted on 120 operational Tehran airport workers including ramp agents, maintenance staff, and cargo handlers. Noise levels were measured using professional dosimeters and sound level meters. Health impacts were assessed via validated questionnaires such as GHQ-28, PSQI, and Job Satisfaction Survey. Blood pressure and hearing evaluations were also performed. Data analysis was conducted using SPSS v26 with t-tests, correlation coefficients, and multivariate regression models. Results Noise levels exceeded 85 dBA in all major operational areas except ground control. Participants exposed to higher noise levels reported a significantly higher prevalence of headaches, poor sleep quality, and elevated systolic blood pressure. Additionally, job satisfaction scores were lower, and reported operational errors were significantly higher in high-exposure groups. Conclusion The study confirms that occupational noise in airport settings adversely affects worker health and performance. Comprehensive noise management strategies and preventive occupational health programs are crucial for protecting airport personnel.
