title: [The influence of drinking on high frequency hearing loss of pilot students].
abstract: OBJECTIVE
  To evaluate the influence of drinking on hearing loss of pilot students, especially on high frequency hearing loss.
  
  
  METHODS
  According to whether drinking, 517 male pilot students were divided into two groups. The balance of all the factors in addition to drinking in both groups was compared. All the students were examined by pure tone audiometry. The statistical data of this research was processed based on a retrospective cohort study.
  
  
  RESULTS
  The damage of high frequency (4-8 kHz) auditory threshold in left and right ear in drinking group were obviously higher compared with control group (P < 0.01). The Morbidity of hearing loss in drinking group was significantly higher compared to control group (χ2 =16.620, P < 0.01).
  
  
  CONCLUSIONS
  Drinking is associated with the hearing loss in pilot students and particularly affects the hearing of high frequency spectrum.
