Abstract：Objective We directed to study the effect of military aircraft noise on hearing of ground crew with different positions. Methods 1714 military ground crew were chosen for the survey. They were divided into 4 groups:Machinery (736), Ordnance (294), Avionics (334), and Special Equipment (350). Hearings of all subjects were tested by electric audiometer. Results Hearing damage occurred in all the four groups of ground crew as follows:Machinery 12.0%,Ordnance 9.5%,Avionics 10.2%, and Special Equipment 12.0%. The high-frequency hearing impairment were very common in ground crew:Machinery 45.1%,Ordnance 45.5%, Avionics 34.8%, and Special Equipment 57.7%, and the incidence for the Special Equipment was significantly higher than the other three groups (P<0.01). Meanwhile, the most sensitive frequency of the high-frequency hearing impairment occurred at 6000 Hz in all the four groups, suggesting a typical"V"-shaped trough in the audiogram. Conclusion For hearing damage, there was no apparent difference among different military ground crew, while high-frequency hearing impairment in the special equipment group was worse than the other three groups.
