噪声对安全注意力影响实验研究

为了研究作业环境中噪声因素对人的安全注意力的影响，对安全注意力类型及品质特征进行分析，建立安全注意力水平模型。设计噪声条件下的安全注意力水平测量实验，通过实验中不同噪声环境下人的安全注意力水平变化，分析噪声对人的安全注意力的影响作用。结果表明，噪声对人的安全注意力具有较为显著的影响作用；安全注意力的广度、稳定性、分配、转移均受噪声影响，安全注意力的稳定性及转移随噪声的增大而降低；当噪声值大于60 dB、70 dB时，噪声对安全注意力的广度及分配的影响较为显著。

Experimental study on influence to safety attention by noise

In order to study the influence of noise factors on safety attention of human in working enviroument, the types and quality characteristics of safety attention were analyzed, and a model on safety attention level was established. The measurement experiment on safety attention level under noise conditions was designed, and the effect of noise on safety attention of human was obtained by analyzing the change in safety attention level of human under different noise environments in the experiment. The results showed that noise has a significant effect on safety attention of human. All the breadth, stability, allocation and transfer of safety attention are affected by noise. The stability and transfer of safety attention decreases with the increase of noise. The noise has a significant effect on the breadth and allocation of safety attention when the noise value is greater than 60 dB and 70 dB respectively.
