为探索噪声水平对人不安全行为的影响规律,采用Captive生理指标数据采集系统,利用SPSS19.0软件,研究被试执行追踪作业时噪声引起的皮电、心率变化,以及失败次数的变化。结果表明:高噪声水平导致高皮电、心率,也引起高失败次数;ANOVO分析显示,性别对生理参数和注意力有显著影响,短时间的噪声暴露不显著影响人的生理参数,但是显著影响人的注意力集中能力;Duncan多重比较显示,中噪和高噪条件下的失败次数值显著高于低噪和安静状态,而低噪和安静状态时差异不明显;回归分析显示,幂函数模型能较好体现噪声水平对注意力的影响。
To explore the influence of noise level on human unsafe behavior, Captive physiological index data acquisition system and SPSS19.0 software were used to study the changes of skin electricity, heart rate and the number of failures caused by noise during the follow-up task. The results showed that: the high noise level led to high skin electricity, heart rate, also caused a high number of failures; ANOVO analysis showed that gender had significant effects on physiological parameters and attention, short-term noise exposure did not significantly affect human physiological parameters, but significant impact People’s concentration ability; Duncan multiple comparisons show that the number of failures in the noisy and noisy conditions was significantly higher than the low-noise and quiet state, while no significant difference between low-noise and quiet state; regression analysis showed that the power function model Can better reflect the impact of noise level on the attention.
