title: [Cross-sectional study of hearing loss among freshmen in university].
abstract: 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.
  
  
  METHODS
  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.
  
  
  RESULTS
  (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.
  
  
  CONCLUSIONS
  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.
