噪声对建筑施工人员作业疲劳影响实验研究

为了研究噪声对建筑施工人员作业疲劳的影响，设计噪声作业生理实验。先通过建筑施工作业疲劳分析确定疲劳测量生理指标，再通过施工作业现场噪声测量确定实验中作业环境噪声等级分类。根据实验中被试者心率指标变化率及作业疲劳自我评价量表对噪声作业疲劳程度影响进行分析，结果表明，施工人员作业疲劳受噪声影响；持续作业15min后噪声对施工人员作业疲劳程度影响显著；作业疲劳程度与作业环境中噪声值成正相关关系；施工人员作业后疲劳恢复程度不受作业环境噪声值大小影响。

Experimental study on influence of noise on work fatigue of construction personnel

In order to study the influence of noise on work fatigue of construction personnel, a physiological experiment of noise work was designed. The physiological index of fatigue measurement was obtained by analyzing the work fatigue of construction, and the classification of noise grade in the work environment of experiment was obtained through the noise measurement in construction work site. The influence of noise on work fatigue level was analyzed according to the change rate of heart rate for the subjects in the experiment and the self-evaluation scale of work fatigue. The results showed that the work fatigue of construction personnel can be affected by noise. Noise has a significant effect on work fatigue of construction personnel after continuing work for 15 minutes. There is a positive correlation between work fatigue level and the noise value of the working environment, but the noise value has no effect on the recovery degree of fatigue after completing work.
