| Outline of Final Research Achievements |
To accumulate knowledge on sound design for next generation vehicles and for its related legislation design, we established following two main subjects: (1) understanding feasible sound design to make pedestrians easily realize the approaching vehicle, (2) understanding adequate sound design to achieve comfort and drivable experience. For the first subject, we conducted a series of psycho-acoustical experiments to examine the feasible sound level and frequency characteristics for the sound with wide range of subjects age. For the second subject, a series of experiments to examine the relationship between frequency shifting and accelerating impression with some audio-visual stimulation. Moreover, another subjective evaluation experiment using the driving simulator that was developed for this present project was conducted. The results were published in the journals, international conferences, and a related body of the UN/ECE vehicle regulation as well.
