Abstract
Electric or hybrid vehicles are very silent, which represents a major advantage for the reduction of noise
annoyance in urban areas. But this makes them dangerous for pedestrians, especially vulnerable ones as visuallyimpaired
people. Current solutions consist in using warning sound so that the exterior noise of an electric vehicle
is as high as for a conventional one. This may cancel the benefit of electric vehicles for the reduction of sound
annoyance. The eVADER project (funded by the European Commission) aims at proposing a prototype car
which combines a high safety and a low noise level. A part of the the work program consisted in perceptual
studies. The goal of these studies was to evaluate the influence of various timbre parameters on the detectability
and the unpleasantness of a warning sound. Results show that it is possible to make an electric vehicle easily
detected while keeping its sound level much lower than the one of a conventional car.
