Occupational noise pollution poses a significant and often underestimated threat to human health, particularly in high-intensity environments such as airports. Military airports, characterized by the operation of powerful combat aircraft like the Su-30MK2, present unique and elevated noise exposure challenges for personnel. Understanding the specific noise characteristics and their prevalence in these specialized settings is paramount for ensuring the well-being and operational effectiveness of aviation technical staff. This study addresses this critical gap by investigating the current noise situation at Kep military airport, aiming to quantify exposure levels and identify key sources. The findings are vital for informing targeted interventions and establishing robust occupational health protocols to mitigate noise-induced health risks among military personnel.

This cross-sectional descriptive study meticulously investigated the noise situation and noise pollution levels at Kep military airport, focusing on the occupational environment of its aviation technical staff. Conducted between May 2024 and May 2025, the research measured sound pressure levels (dBA) at 43 distinct locations across the airport, including aircraft parking aprons, technical inspection zones, and workshops. The primary objective was to quantify noise exposure and identify the dominant noise sources within this specialized setting. The findings reveal a critical concern: a staggering 93.02% (40 out of 43) of the measured locations exceeded the national permissible standard for occupational noise (QCVN24:2016/BYT). The average overall sound pressure level across the study facility was recorded at 100.54 ± 12.05 dBA. Specifically, the Su-30MK2 aircraft parking apron exhibited an average equivalent sound level of 105.84 ± 9.83 dBA, with technical inspection areas reaching peak levels of 114.98 dBA. The study comprehensively analyzed noise intensity across various frequency bands, demonstrating high exceedance rates particularly from 125 Hz to 8000 Hz. These results underscore the unique and severe occupational health challenges faced by military personnel due to the powerful noise sources, primarily from combat aircraft engines operating at full thrust (up to 148 dBA). The study implies an urgent need for tailored noise control strategies, enhanced hearing protection protocols, and specialized occupational safety guidelines that account for the extreme nature of military airport operations, which often surpass the noise exposure encountered in commercial aviation.
