| Research Abstract |
Although the motors equipped on electric vehicles (EVs) are designed to provide calm environments to drivers, pedestrians have trouble recognizing their approach because they are too quiet. Warning sounds have been developed to solve this. However, it is still problematic for pedestrians. This study proposes a warning sound for pedestrians by using amplitude fluctuations for sounds to enhance their ability to be detected and acceptable for neighborhoods. The warning sound with characteristics of the fluctuation of the gasoline engine was synthesized using a procedure proposed in our previous study. A detectability and acceptability by pedestrians were assessed. The result revealed that fluctuating motor sounds effectively enabled people to notice the approaching electric vehicles, and that those sounds are relatively acceptable.
