目的：研究舰船噪声岗位作业人员听力保护理论，为噪声防护措施提供科学依据。方法依据声学理论和声能量等效原理研究岗位噪声暴露量。结果导出了噪声暴露量解析式，发现降低环境噪声、选择隔声较好的护听器、坚持佩戴护听器、减少每天噪声暴露时间、完善噪声防护法规五项措施是控制噪声暴露量的技术途径。结论噪声暴露量解析式构成了噪声防护措施的完备集。

Research on noise exposure control theory for the protection of the naval ship crew exposed to occupational noise

Objective To investigate hearing conservation theory for the protection of the naval ship crew exposed to occupa -tional noise , so as to provide scientific evidence for the development of noise protection measures .Methods Occupational noise expo-sure level was studied in the light of sound theory and equivalent principle of sound energy .Results A mathematical formula for the de-termination of occupational noise exposure level was thus brought about .The following countermeasures were practical approaches for the control of noise exposure levels：the decrease of environmental noise , the selection of better ear attenuators , the persistent wearing of ear attenuators or mufflers , the decrease of daily noise exposure time , and the perfection of noise protection regulations .Conclusion The mathematical formula for the determination of occupational noise exposure level forms a close coverage of the noise protection methods .
