Contribution of noise and vertical vibration to comfort in a driving car
Résumé
In a driving car, passengers are submitted to complex sound and vibration stimuli. These stimuli are integrated in a complex way and contribute to the comfort for passengers. This talk will summarize some work related to that field, during which a noise and vibration simulator was used to evaluate the relative contributions of noise and vibration to comfort in a driving car. A first step showed that this evaluation was only slightly modified by vision (of a video showing the road on which the car was driven on). Then a complete experimental plan was used : sound and vibration levels were independently varied and the subjects were asked to evaluate the comfort of the overall situation. The results were in concordance with the existing literature, i.e. the interaction between both stimuli is very small. But the relative contributions of sound and vibration to comfort were different from the existing models; this was certainly due to the range of levels used in that experiment, which represented usual levels measured in cars.
