为深入研究应急疏散中声光刺激对人员生理和心理扰动的影响,提出从微观方面监测人员疏散过程生理指标变化的方法。运用试验生成系统(E-Prime)软件模拟火灾环境,记录被测人员在无刺激、声刺激、光刺激和声光刺激条件下的应急反应过程,分析人员反应速率及反应倾向性;探究被测人员在各情景下的心率、心电和血压等生理指标变化情况,通过研究这些指标的变动规律,剖析其与被测者心理活动的关系。结果表明,声光刺激对应急疏散下人员反应速率及反应倾向性影响显著,会引起心率、心电图和血压等生理数据波动;还会使人员产生紧张、恐慌情绪,并加重恐慌心理下出现的从众行为。
In order to further study the effect of acousto-optic stimulation on physiological and psychological disturbances in emergency evacuation, a method to monitor the changes of physiological indexes in personnel evacuation process is proposed. The E-Prime software was used to simulate the fire environment. The emergency response process of the tested persons under no stimulation, acoustic stimulation, light stimulation and acousto-optic stimulation was recorded, and the reaction rate and reaction tendency were analyzed. The changes of physiological indexes such as heart rate, ECG and blood pressure in different situations were analyzed. The changes of these indexes were analyzed to analyze their relationship with the mental activity of the tested subjects. The results showed that the acousto-optic stimulation had a significant effect on the reaction rate and reaction tendencies under emergency evacuation, which would cause fluctuation of physiological data such as heart rate, electrocardiogram and blood pressure. It would also cause tension and panic among staff and aggravate the obscurity behavior.
