This pilot study examined early changes in hearing thresholds and psychological well-being among Republic of Korea Air Force soldiers.\n Methods:<\/jats:bold>\n Newly enlisted soldiers were enrolled at baseline (\n n<\/jats:italic>\n \u2009=\u200996); 52 completed 8-month follow-up. Air-conduction thresholds were measured at 250 to 8000\u2009Hz. Psychological and sleep outcomes were assessed using the Patient Health Questionnaire-9 (PHQ-9), Beck Depression Inventory (BDI), Center for Epidemiologic Studies Depression Scale-Revised (CESD-R), Beck Anxiety Inventory (BAI), Pittsburgh Sleep Quality Index, and Insomnia Severity Index. Regression models adjusted for noise exposure and shift work evaluated associations between threshold shifts and psychological changes.\n Results:<\/jats:bold>\n Subclinical threshold shifts of 2 to 3\u2009dB occurred at 4000\u2009Hz in the right ear [False Discovery Rate\u2013adjusted\n P<\/jats:italic>\n -values (\n P<\/jats:italic>\n FDR<\/jats:sub>\n )\u2009=\u20090.007] and left ear (\n P<\/jats:italic>\n FDR<\/jats:sub>\n \u2009=\u20090.047), and at 250\u2009Hz in the right ear (\n P<\/jats:italic>\n FDR<\/jats:sub>\n \u2009=\u20090.038). PHQ-9, CESD-R, and BAI scores increased over follow-up (all\n P<\/jats:italic>\n raw<\/jats:sub>\n < 0.05), although these changes were not significant after FDR adjustment (all\n P<\/jats:italic>\n FDR<\/jats:sub>\n > 0.05). No incident tinnitus was reported. In adjusted models, 4000\u2009Hz threshold shifts showed borderline associations with increased BDI (\n \u03b2<\/jats:italic>\n \u2009=\u20090.350,\n P<\/jats:italic>\n FDR<\/jats:sub>\n \u2009=\u20090.057) and CESD-R scores (\n \u03b2<\/jats:italic>\n \u2009=\u20090.384,\n P<\/jats:italic>\n FDR<\/jats:sub>\n \u2009=\u20090.057).\n Conclusion:<\/jats:bold>\n Short-term aircraft noise exposure was associated with early subclinical auditory shifts and numerical worsening of psychological measures. The 4000\u2009Hz shift may represent a preliminary marker of depressive symptom emergence, supporting further investigation of sensory\u2013psychological interactions in high-noise military environments.\n
