摘要
目的探讨大学生使用随身听对听力健康的影响及对其可能造成听力损伤的特征进行评价和估测。方法通过对研究对象进行纯音听力测试和主观听力状况的相关问卷调查,分析接触随身听使用时间与听力健康状况的关系。结果随着使用随身听时间的延长,各频率段听阈有上移趋势。经方差分析,观察组与对照组听阈比较,差异有统计学意义(P<0.05);1~3 a的观察组与对照组的听阈比较,差异无统计学意义(0.01<P<0.05);3~5 a的观察组与对照组听阈比较,差异有统计学意义(P<0.05),即使用随声听3~5 a的人群听阈发生改变。5a以上观察组与对照组比较,各频率段都有统计学意义(P<0.05),即使用随身听5 a以上能对听力造成损伤。采用相关分析,各频率段rs′有统计学意义(P<0.05),即听阈的大小与使用随身听的时间呈正相关。结论不合理的使用随身听设备会使人们的听阈下降,使用时间越长,听力损伤越严重。因此,应该加强听力健康相关知识的宣传。
Objective To investigate effect of long-time listen to earphones equipped Walkman on hearing loss of college students. Methods Questionnaire about the relationship between pure tone hearing tests and subjective hearing of experiment subjects was conducted. The duration listening to earphones and status of hearing loss were analyzed. Results As the duration listening to earphones prolonged, the hearing thresholds of various frequency ranges tended to shift upward. The difference between the observed group and control group was significant. The difference of hearing thresholds between the 1 - 3 a observed group and control group was not significant. However, there was significant difference of hearing threshold in 3 ~ 5 a observation group in comparison with the control group（P^0.05）. That meant when listening to earphones equipped Walkman for 3 - 5 years, the hearing threshold would change. In〉 5 a observed group changes occurred in various frequency ranges, and the difference was significant（P〈0.05）. That was to say when listening duration exceeded 5 years the hearing loss would result. Correlationanalysis showed that the differences in rs＇ of various frequency ranges were significant （P〈0.05）demonstrating the changes of hearing thresholds were positively correlated with the listening duration. Conclusions Inappropriate listen to earphones equipped Walkman could lower the hearing threshold. The longer listen to, the more serious the hearing loss would be. Therefore, the publicity of hearing conservation should be reinforced.
