Abstract：Objective To establish an information technology based dynamic military noise and hearing monitoring sys-tem. Methods A total of 496 new recruits received physical examinations and hearing tests. Using the information, a dynamic military noise monitoring system was established on a local computer network infrastructure. All auditory data were collected following a standard hearing examination protocol. The PASW Statistics 18 software was used for statistical analysis. Results The dynamic monitoring system was successfully established and the testing of the 496 soldiers using the system was complet-ed in three days. The soldiers aged from 17-25 years (average 19 years). Abnormal tympanograms were seen in 5 and various degrees of hearing loss based on the GJB 2121-94 standards were identified in 17 of these solders. Abnormal auditory thresh-olds were noticed in 73 ears (68 mild and 5 moderate). Hearing levels at different frequencies showed some differences were (P<0.05), especially at 3 kHz and 6 kHz (P<0.01). Conclusions This study indicates that the dynamic hearing monitoring sys-tem can collect and analyze hearing information personnel at potential risk of military noise exposure in a easy and fast fashion. The baseline data in this study indicate that many new recruits have hearing loss of various levels even before they were ex- posed to military noise.
