【摘要】：为了研究煤矿噪声对作业人员注意力的影响,采用舒尔特方格法对20名被试者进行5 d的测试,以反应时间和错误次数为评价标准,测试了5种不同分贝煤矿噪声下的注意力水平。运用SPSS,Excel等软件对实验所得的反应时间、出错次数和超时次数进行分析。结果表明:不同噪声等级刺激对矿工的注意力水平存在差异。噪声等级在35~85 db时,注意力水平变化不显著,当噪声等级超过85 db后,对注意力水平的影响趋于显著。煤矿安全规程规定井下作业场所的噪声不应超过85 db,如果超过此临界值,噪声会对矿工的注意力产生较大的负面影响,导致不安全行为的发生;不同噪声等级分别与矿工出错次数、超时次数成正相关关系。当噪声等级在35~85 db时,随噪声刺激的增大,矿工出错次数的增长率先增大后减小,而超时次数的增长率刚好相反。噪声等级超过85 db后,矿工出错次数、超时次数的增长率一致。
[Abstract]:In order to study the effect of coal mine noise on the attention of workers, 20 subjects were tested with Schulte square method for 5 days. The response time and the number of errors were used as the evaluation criteria. The attention level of five different decibel coal mines under noise was tested. The reaction time of the experiment was measured by using SPSS Excel and other software. The results show that different noise levels have different effects on miner's attention level. When the noise level is 35 ~ 85 db, the change of attention level is not significant, and when the noise level exceeds 85 db, the change of attention level is not significant. The coal mine safety regulations stipulate that the noise of the underground working place should not exceed 85 db. if it exceeds this critical value, the noise will have a great negative effect on the miner's attention and lead to the occurrence of unsafe behavior. Different noise levels have a positive correlation with the number of miner errors and the times of overtime. When the noise level is 35 ~ 85 db, the growth rate of the number of miner errors increases first and then decreases with the increase of noise stimulation. When the noise level exceeds 85 db, the number of miner errors is the same.
