环境噪声对中学生大脑工作能力影响的探讨

本文采用国产ND10型精密声级计对两所中学进行了环境噪声水平测定，并对部分学生测定了大脑工作能力，结果表明受环境交通噪声干扰严重的甲校其噪声水平大大超过卫生标准．学生容易发生学习疲劳，大脑工作能力下降。而作为对照的乙校由于自身学习，活动的影响所产生的噪声也超过了卫生标准，但仍比甲校低很多，故对大脑工作能力影响较小。

Influence of environmental noise on the cerebral working ability of middle school students

Environmental noise in two middle schools was detected with the Chinese-made precision sound presure instrument and the cerebral working ability of partial students in these schools was measured.The results show that the great noise in school A from outside environment is over the standard of health, the students tire easily in their study and their cerebral working ability come down while the noise in school B ( as controls) is also over the stan-dard of health due to the influence of its daily activities, but much lower than that in school A and less influences the students' cerebral working ability.
