随着现代化工业,交通运输业的发展,环境噪声污染日趋严重,给人们工作、生活、学习、健康带来严重危害。研究环境噪声对青少年听力危害,国内报告尚少。我们从探讨在不同环境噪声下对中学生听力影响及早期损害的特点为目的,于1983年10月在洛阳市两所中学对474名学生进行了听力及环境噪声测定。发现噪声组学生听力损失(15.29%),比对照组(5.82%)明显提高,现将调查方法及结果报告如下:
With the development of modern industry and transportation industry, environmental noise pollution is becoming more and more serious, which brings serious harm to people’s work, life, study and health. Study of environmental noise on the hearing hazards of young people, the domestic report is still small. We studied the hearing and environmental noise of 474 students from two secondary schools in Luoyang in October 1983 for the purpose of exploring the hearing impact and early injury of middle school students under different environmental noises. Hearing loss (15.29%) in noise group was significantly higher than that in control group (5.82%). The investigation methods and results are reported as follows:
