Objective: To analyze the literature of related research reports on occupational hearing loss (ONIHL) , study the characteristics of the subject and determine the research hotspots. Methods: In December 2020, PubMed database was searched by bibliometrics for ONIHL published in PubMed database from January 1971 to December 2020. Bicomb 2.03 software was used to extract the subject. The publication year, publication country, source magazine and subject words were summarized and analyzed. Results: A total of 1 473 papers were included in this study, and the number of papers was 66 from 1971 to 1980, and 628 from 2011 to 2020, an increase of nearly 10 times. The top three countries were the United States, China and Germany, with 31.5% (464/1473) , 11.5% (171/1473) and 6.2% (91/1473) ; The cross-sectional study was the most applied type; The top five words for 2011-2020: Mental Illness, polymorphism, cardiovascular disease, high frequency hearing impairment and standards and regulations. Conclusion: Susceptibility Genes, Psychological Disorders, Cardiovascular Diseases and Risk Assessment are hot areas in ONIHL at present. Researchers should focus on major fields and grasp future trends as a whole.
目的： 对职业性听力损失（Occupational noise-induced hearing loss，ONIHL）相关研究报道进行文献分析，揭示研究主题特征并确定其研究热点。 方法： 于2020年12月，利用文献计量学方法，检索PubMed数据库公开发表的ONIHL相关文献，文献检索时间范围为1971年1月至2020年12月，采用Bicomb 2.03软件进行主题提取，对发表年代、发表国家、杂志来源、主题词进行汇总和分析。 结果： 共纳入文献1 473篇，1971至1980年文献发表数量为66篇，2011至2020年文献发表数量为628篇。文献发表数量位居前三位的国家为美国、中国和德国，文献发表数量占比分别为31.5%（464/1 473）、11.5%（171/1 473）和6.2%（91/1 473）；研究类型以横断面研究为主；重点行业为：军人、采矿业、冶炼业、建筑业；主题词主要包括：基因多态性、心理疾患、标准与法规。 结论： ONIHL研究重点关注易感基因、心理疾患、心血管疾病以及风险评估，为职业噪声相关主题的深入研究提供参考。.
