Influence of Vehicle Interior Noise and Steering Vibration on the Uncomfortableness at Vehicle Cruising

Abstract

In this study, a subjective evaluation test about uncomfortable feeling was carried out. Vehicle interior noise and steering vibration having various levels were presented in a sound chamber through headphones and dummy steering wheel. As the result, the interior noise had larger influence on the uncomfortableness than the steering vibration in a group. On the contrary, the vibration had larger influence than the interior noise in the other group. In addition, this characteristic was clarified to depend on the participants' point of subjective equality between the interior noise and the steering vibration.
