Abstract: This paper discusses two studies which address the perception of both transient and steady state sound and vibration experienced by drivers in vehicles. While past studies with railway and aircraft sound and vibration showed varying degrees of sound and vibration interaction, the results of these two studies showed little evidence of interaction. Additionally, both sound and vibration appeared to contribute about equally to the overall NVH perception. Other researchers have observed that the strongest modality tends to dominate perception, but that effect was not observed in the studies presented here.

Keywords: vehicle noise; vehicle vibration; harshness; interaction; paired comparison; sound and vibration perception; NVH perception; simulation; transient road input; steady-state road input.
