Résumé

Sound and vibration can be considered as the two main sources of discomfort when driving. The objective of this study is to quantify the relative influence of each of these sources on overall discomfort. Based on knowledge of the relative influence of vibration sources in interaction with the driver, such as seat, floor or steering wheel. Vibration situations have been generated in a way that each vibration interface induces an equivalent level of discomfort. In a driving simulator, showing a straight road, 20 sound and vibration situations were presented to 15 participants. Vibration levels ranged from 110 to 130 dB, 100 to 120 dB for the floor and seat (0 dB ref : 10-6 m/s2) added with a rolling noise between 85 and 110 SPL. For each situation, the participant were asked to rate their overall feeling of discomfort, using a Borg scale between 0 and 50. This experiment evaluates the relative discomfort induced by noise and allowed to determine their relative weighting in an overall discomfort index. Results and limitations will be presented at the congress.
