Objective: To understand the current situation of high-frequency hearing loss of workers exposed to occupational noise in Hubei Province and its multi-level influencing factors. Methods: In June 2021, the basic information, occupational history, physical examination results and other relevant information in the "Occupational Health Examinations Case Cards" for noise workers in Hubei Province in 2020 were extracted from the subsystem of the "China Disease Prevention and Control Information System". Multilevel level of logistic model was used to analyze the related factors of high-frequency hearing loss of noise-exposed workers. Results: In 2020, the incidence rate of occupational high-frequency hearing loss in Hubei Province was 8.25% (6450/78152), and the incidence rate in various regions of the province ranged from 1.13% to 19.87%. At the individual level, male, ≥ 30 years of age, 6-10 years of service, small and micro enterprises, as well as construction, mining, manufacturing, transportation and rental services were the risk factors for high-frequency hearing loss (P<0.05). The risk of high-frequency hearing loss among workers in foreign-funded enterprises was significantly lower than that of workers in state-owned/collective enterprises (P<0.05). At the regional level, the younger the age of the employees, the lower the risk of high-frequency hearing loss (P<0.05). There was no significant correlation between the regional economic level and the risk of high-frequency hearing loss (P>0.05) . Conclusion: The incidence rate of occupational high-frequency hearing loss in Hubei Province is low in 2020, but the incidence rate varies greatly in different regions of the province, mainly due to differences in employment age, while the development of regional economic level has not reduced the risk of occupational high-frequency hearing loss.

OBJECTIVE:
The purpose of the present study was to investigate the prevalence of hearing loss by studying the current status of hearing loss, risk factors of hearing loss, exposure level of noise, and everyday habit of hearing in a group of university students, so as to provide information for hearing loss prevention in university students.
METHOD:
According to the purposive sampling method, 642 freshmen students participated in the study. Pure tone audiometry, and exposure level of noise scale were performed in all participants.
RESULT:
(1) According to the hearing loss criterion of WHO/PDH97.3, high frequency hearing loss, and noise induced threshold shifts, the hearing loss prevalence was 0.36%, 20.91% and 6.73%, respectively. (2) Multivariant Logistic regression analysis of high-frequency hearing loss indicated that traffic noise exposure and ear infection were risk factor of high frequency hearing loss.
CONCLUSION
There is a high prevalence of high frequency hearing loss in university students (20.91%), which was high related with traffic noise exposure and ear infection.
