Electric and hybrid vehicles are very silent, which represents a major advantage for the reduction of noise annoyance in urban areas. The goal of eVADER project is to develop a prototype vehicle combining a high safety for pedestrian and a low noise annoyance for city residents. Several technical solutions are developed: an automatic pedestrian detection device; a set of loudspeakers focusing the sound in the direction of the detected pedestrian; a warning sound designed so that it can be detected in an urban environment at a low level. This chapter describes three listening test experiments: two of them aimed at evaluating the influence of some timbre parameters on the detectability and annoyance of warning sounds, and a third one intended to determine whether some information about the speed of the car can be evoked by the warning sound, without any training of the listener.
