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。 This paper reports for the first time in China the impact of railway noise on students’ thinking ability. The use of field recorded railway noise control experiments, the results show that railroad noise can significantly reduce the ability of thinking. There was a significant decrease in working ability and memory ability during the experimental noise load period compared with the intermittent period, and Grade A (long-term exposure to railway noise environment) was more significant than that of the non-exposed group. In this study, it is reasonable to assume that the threshold of school environment noise annoyance is below 50 dB.
