Sound and vibration influence overall ride comfort in a combustion passenger car under different driving scenarios

Artikel i vetenskaplig tidskrift, 2023

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.
