摘　　要：目的:了解西安市中学生MP3使用情况及对听力的影响,探讨防治策略。方法:用分层随机整群抽样法对西安市1 567名中学生进行问卷调查、耳科查体及听力学检查,数据用SPSS13.0统计软件处理。结果:①MP3在中学生中的持有率达到85.2%,每天平均使用时间(1.41±1.11)h;②接噪组的纯音听阈与对照组相比明显升高(P<0.01),且随着MP3使用时间的延长,听力受损的检出率增高;③自觉症状检出率随着MP3使用时间的延长而增高。结论:MP3可以对中学生的听力造成危害,并可伴发神经衰弱综合征。Objective：To understand the usage of MP3 and effects on hearing of middle school students in Xi＇an,and discuss controlling strategies.Method：Stratified random cluster sampling method was used in the 1 567 middle school students in Xi＇an through questionnaire survey,ear examination and hearing examination,data were analysed by the SPSS13.0 statistical software.Result：①The rate of holding MP3 in the middle school students was 85.2%.Average daily use time was（1.41±1.11）h.②The noise group of pure tone hearing threshold was significantly higher compared with the control group（P0.01）,and increased the detection rate of hearing loss with the increasing use of MP3.③The detection rate of symptoms increased with the increasing use of MP3.Conclusion：The usage of MP3 can harm hearing in middle school students,which can result in neurasthenic syndrome.
