Résumé

Up to now, the different studies dealing with the interaction between acoustics and vibrations were, in most cases, realized on global annoyance. In this paper, we want to focus on the influence of vibrations on the dieselness rating. Indeed, this article presents the results obtained with a vibro-acoustics test during which, the participants are exposed to sound only and sound and vibrations simultaneously. This perceptual test was realized on a vibration bench with headphones. During this experiment, participants are asked to evaluate the diesel character (called dieselness in this article) of six different driving situations on a continuous scale from 0 (no dieselness) to 1 (dieselness). The results from this study allow to identify the influence of vibrations (from the driver seat and from the steering wheel) on the evaluation of the dieselness. The results show that the participants give scores higher (more diesel) or equal (as diesel) with vibrations than without. However, the statistical analysis allows to conclude that the difference between the vibro-acoustic score and the acoustics score is in general not significant.
