As the autonomous driving section gets longer, the lowered driver's vigilance decreases situation awareness and increases the accident rate upon taking over [1]. In a previous study, the positive notification could improve situation awareness and driving performance on take-over in autonomous driving. This study focuses on sounds of secure areas for autonomous driving. The experimental design consists of three conditions (machine, instrument, music) according to musical attributes and examined the effect of situation awareness when taking over and usability. Music has a similar impact with machine sound on situation awareness and usefulness. But the instrument sound with chords showed the lowest result. Also, participants evaluated music as the least unpleasant and the least untrustworthy. This study could contribute to the auditory UX of autonomous vehicles.
