Abstract : One of the reasons for hearing impairment is due to excessive noise exposure. These encounters can cause permanent hearing loss, which can impair verbal communication with others and decrease the quality of a person's social life. The most prevalent place of exposure to excessive noise and the most common reason of noise-induced hearing impairment is noise exposure in the military environment. The purpose of this study was to investigate the prevalence of auditory disorders in conscripts and the role of routinely audiometric screening. In this cross-sectional study, the invited soldiers to the Islamic Republic of Iran Army were investigated in Tehran. Then, their data such as age, history of exposure to high-intensity noise, history of hearing impairment in the family, history of ear trauma were collected by a questionnaire. Audiometric tests included pure tone audiometry, tympanometry, and acoustic reflex was conducted. The presence of hearing impairment and its type (conductive - sensorineural) were evaluated according to audiometric tests and its relationship with possible risk factors. According to our results, among the 207 studied soldiers, the prevalence of hearing impairment was 14%, and the most prevalent type was sensorineural hearing impairment type (SNHL) with a prevalence of 7.7% and the highest rate of conflict was in high frequencies. Sensorineural hearing loss had a significant relationship with the history of hearing loss in the family. Also, there was a significant relationship between conductive hearing loss and ear trauma. Routine hearing screening including otoscopic ear examination and basic and comprehensive audiometric tests, impedance and acoustic reflex, seems essential for all soldiers at the beginning of their military service and military training and identifies probable ear disorders
