Abstract: A variety of factors, such as sound, vibration and seating system influence the perceived overall ride comfort in passenger cars. However, these influences are not constant across different driving scenarios. The purpose of this study is to identify how human experiences regarding sound and vibration varied in eight different driving scenarios. A user study was conducted with ten participants in a combustion passenger car. The results showed that dynamic discomfort was affected by induced body movement, annoying sounds and the discordance between sound and vibration. Tyre-road noise and wind noise dominated the perceived sound annoyance at lower and higher speed, respectively. The vibration annoyance was mostly judged by induced body movements. The conclusion was that the influences of sound and vibration on perceived ride comfort change in different driving scenarios, and thus, overall ride comfort should be evaluated in different ways depending on the chosen driving scenario.

Keywords: ride comfort; sound; vibration; car passenger; discomfort.
