Emergency sound intervals for danger alert

抄録

A rapid evacuation is important for reducing damage caused by major earthquakes. This research focuses on an emergency alert system applied during an earthquake, specifically, a system that provides an emergency alert interval between two mono sounds. Adequate research has yet to be conducted in this field; therefore, intuition is important. The present research is useful for analyzing ways to reduce the damage caused by large disasters. A total of 36 students participated. To search for an emergency alert interval between two mono sounds, we used an anklet to search for an image. We then revived the association using a factor analysis. As a result, we divided the 10 evaluation factors into three groups and labeled them the unrest factor, impact factor, and hardness factor. The unrest factor was connected to the alert chord, and the impact factor was connected to the sound interval of the alert. Thus, emergency alerts evaluated these two factors.
