ObjectiveTo carry out a questionnaire survey on the noise and protection of flight support personnel on the deck of a large naval surface ship，and to put forward targeted countermeasures and suggestions for noise protection based on the development of foreign militaries and the actual situation of Chinese military.

MethodsA questionnaire survey on noise and protection was conducted among the flight support personnel of a large naval surface ship. By comparing the survey results of flight support personnel of different types of air craft and battle positions，the issues related to noise and protection，namely noise protection，protective gear use，health effects，knowledge acquisition，and health support，were analyzed and discussed.

ResultsAmong the 211 flight support personnel surveyed，74.88% wore noise protective gear at work，but the incidence of noise-induced subjective temporary hearing impairment was still 91.77%. The rate of wearing noise protective gear among fighter jet support group（100%）was significantly higher than those of the helicopter group（47.71%）and the rest of the battle station group（78.75%）. However，the incidences of subjective temporary hearing impairment among flight support personnel of different aircraft types and battle stations were not statistically significant（ P>0.05），and more than half of them felt that their subjective symptoms continued to develop and worsen after the onset of transient impact. Among those who wore protective gear，36 used at least two kinds of gear in combination，but 88.89% still subjectively experienced transient communication problems and short-term tinnitus. Among the 211 personnel：25.12% did not wear noise protective gear，and the reasons were not being provided with protective gear（84.9%），protective effect of the gears was mediocre（7.55%），and the comfort of protective gears was poor（33.96%）；74.88% had a strong desire to gain knowledge of noise protection，with the fighter jet support group accounted for the highest percentage（93.75%）；only 39.81% of the flight support personnel had attended organized noise protection education and training；73.93% attended annual medical examinations，but only six people had specific medical examination item on noise；26.07% did not attend annual medical examinations，among whom，81.82% hoped to get regular medical examination.

ConclusionThe noise on the deck of a large naval surface ship is a significant health hazard to flight support personnel，and noise protection research programs on noise exposure monitoring of flight support personnel，development of new noise protective gear，health education，and special medical examination should be carried out promptly.
