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。
In order to study the influence of coal mine noise on the attention of the workers,20 subjects were subjected to a5-day test by Shulter＇s grid method. Five different decibels were tested with the reaction time and the number of errors. The level of attention under noise. The reaction time,the number of errors and the number of times of time were analyzed by SPSS and Excel software. The results show that there are differences in the attention level of miners with different noise levels. Noise level between 35 db and 85 db,attention level is not significant,when the noise level exceeds 85 db,the impact of the level of attention is more significant. Comply with the coal mine safety regulations on the underground workplace noise should not exceed 85 db provisions,if more than this threshold,the noise will have a greater negative impact on miners＇ attention,resulting in unsafe behavior; different noise levels with miners The number of errors and times to a positive correlation. When the noise level in the 35 db and 85 db this interval,with the increase in noise stimulation,the number of miners mistakes growth rate increased first and then reduced,while the number of times the growth rate is just the opposite. Noise level more than 85 db,the miners wrong times,the number of times the growth rate of the same.
