【摘要】：為了研究煤礦噪聲對作業(yè)人員注意力的影響,采用舒爾特方格法對20名被試者進(jìn)行5 d的測試,以反應(yīng)時間和錯誤次數(shù)為評價(jià)標(biāo)準(zhǔn),測試了5種不同分貝煤礦噪聲下的注意力水平。運(yùn)用SPSS,Excel等軟件對實(shí)驗(yàn)所得的反應(yīng)時間、出錯次數(shù)和超時次數(shù)進(jìn)行分析。結(jié)果表明:不同噪聲等級刺激對礦工的注意力水平存在差異。噪聲等級在35~85 db時,注意力水平變化不顯著,當(dāng)噪聲等級超過85 db后,對注意力水平的影響趨于顯著。煤礦安全規(guī)程規(guī)定井下作業(yè)場所的噪聲不應(yīng)超過85 db,如果超過此臨界值,噪聲會對礦工的注意力產(chǎn)生較大的負(fù)面影響,導(dǎo)致不安全行為的發(fā)生;不同噪聲等級分別與礦工出錯次數(shù)、超時次數(shù)成正相關(guān)關(guān)系。當(dāng)噪聲等級在35~85 db時,隨噪聲刺激的增大,礦工出錯次數(shù)的增長率先增大后減小,而超時次數(shù)的增長率剛好相反。噪聲等級超過85 db后,礦工出錯次數(shù)、超時次數(shù)的增長率一致。
[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.
