RESEARCH ON MAINTENANCE OF DRIVER’S AROUSAL LEVEL USING STEADY RUNNING NOISE

摘要

In order to prevent a driver from dozing as the result of a low arousal state, we generatedwake-up sounds by processing the pressure, tonal quality, and rhythm of the steady runningnoise generated by a car.In this paper, we evaluated wake-up sounds in a real environment where music or a radio isbeing played. The results showed that playing music can generate a transient arousal state.Moreover, playing wake-up sounds along with music can maintain the arousal state for alonger period than playing music alone. In addition, we focused on the habituation to wake-upsounds, generated wake-up sounds that made habituation more difficult, and evaluated thesounds’ effectiveness for arousal maintenance. The results showed that the wake-up soundsthat prevented habituation could maintain the arousal state for a longer period than thewake-up sounds that did not prevent habituation.
