The ultra-compact mobility has positive characteristics as easily make turns owing to their compactness and low environmental impact because of using an electric motor as a power source. However, interior noise, which includes road and wind noise from the outside, has a significant impact on the comfort of an occupant in an interior space. We aim to create a new active noise control system for ultra-compact mobility to provide a comfortable interior sound environment. The feature of our proposed system is focused on interior sound design control for providing ride comfort according to various situations and the space preference of a passenger not only noise reduction. In this study, we considered the effect of interior sound for the driver under the driving condition. Regarding comfortability evaluation, we used an appearance rate of brain wave which is one of the biological information for quantitative evaluation and virtual analogue scale which is one of the subjective evaluation methods. Both evaluation methods were used to make a quantitative comfort evaluation.
