Abstract:
Noise-induced hearing loss is a significant occupational hazard for police personnel. Intense noise from training and military activities can permanently damage the inner ear, leading to hearing loss. The aim of this study is to compare the hearing of Turkish Special Forces personnel with that of healthy individuals. We included 50 male police from Turkish special police forces team and 51 healthy males in the study. After a detailed medical history and a comprehensive otolaryngologic examination, pure-tone audiometry was conducted. Hearing levels were compared between the special forces and the control group. The study included 50 male police from Turkish special police force (study group, mean age 32 ± 3 years) and a control group of 51 healthy males (mean age 32 ± 6 years). Right ear hearing thresholds of 500, 1000, 2000, 4000, 6000, and 8000 Hz were significantly greater in the special forces group, compared to the control group (P < .001 and P = .002, respectively). In addition, left ear hearing thresholds of 500, 2000, 4000, 6000, and 8000 Hz were significantly greater in the special forces group, compared to the control group (P = .03 and P < .001, respectively). This study revealed significantly higher hearing thresholds in special police forces compared to a healthy control group. This suggests chronic loud noise exposure during training and military operations might be causing hearing loss among these personnel. To safeguard the auditory health of this population, robust hearing conservation programs must be implemented. Early identification of hearing loss is essential for mitigating its impact and providing appropriate support.
