铁道噪声影响学生思维能力的实验研究

本文在国内首次报道铁道噪声对学生思维活动能力的影响。采用现场录制的铁道噪声进行对照实验研究,结果表明,铁道噪声能明显降低学生思维能力。在实验噪声负荷期作业能力与记忆能力较间歇期明显下降,甲校(长期暴露于铁道噪声环境)较乙校(非暴露组)更为显著。本次研究认为学校环境噪声烦恼度阈值定为50分贝以下较为合理。

THE EXPERIMENTAL STUDY OF THE EFFECT OF THE RAILWAY NOISE ON THE ABILITY OF THINKING IN PUPILS

The effect of railway noise on the pupils' ability of thinking was reported in this article for first time in the country. Two groups of pupils of fifth grade in primary schools were chosen as experimental objects. One group from school A was exposed to railway noise for a long term, the other one without exposure from school B was used as control. The experimental noise from railway was used as the source of noise. The seeing-answering method was adapted to measure the noise dose in the work-site and the ability of fast memorizing the degree of hearing was also investigated in the same time. The result shows that the noise can affect the pupils' ability of thinking intensively, especially during the period of exposure. The effect in school A is more severe than that in school B. The research indicates that 50 dB is the acceptable threshold of the boring degree.
