We studied the severity of hearing at the time of the study by audiography, based on the available medical records compared with the indicators of acuity before entering the military service. The mean values were determined, the reliability was assessed using Student's t-test, the dependence was determined using the Pearson correlation coefficient. Results. There was a significant decrease in the acuity of hearing in the main group compared with the period before admission to military service, as well as with control group 2 and control group 3, the decrease in hearing acuity in control group 1 is unreliable. Conclusions. In persons with prior work experience under conditions of production noise, harmful military service conditions can lead to the emergence and development of early forms of neuro-sensory hearing loss, which requires a set of preventive measures preventing the development and progression of this disease when returning these citizens to work in the main specialty of National economy
