Compared with golden standard(pure tone audiometry), Sen=58.5%, Spe=96.7%, PV+=78.9%, PV-=91.7%, overall accuracy=90.0% . The sensitivity for women was higher than men.Conclusion:The questionnaire produced high efficiency and specificity values.It could be used in mass hearing screening, particularly in remote and rural area, although the sensitivity was as low as most questionnaires.
