In recent years, the silence of hybrid cars is regarded as questionable from a viewpoint of pedestrian protection. This situation tends to obligate to add the car sound. In this study, we focused on half order spectrum and then subjective preference (subjective annoyance) of acceleration car sound for subjects who infrequently drive a car and who frequently drive it was evaluated. In addition, a sinusoidal model was adopt for acceleration car sound synthesis and the auditory impressions of car acceleration sound was examined using the psychological method and brain magnetic fields.
