A Study on Stevens' Power Law Applied on the Human Perception of a Running Vehicle Transmitted Vibrations

Abstract

This paper studies the way humans perceive vibrations induced by a running vehicle, starting from Stevens’ Power Law. The measurable physical magnitude was the acceleration transmitted to the hand-arm system. The measurements were made with MEASTRO 01dB. A new four components model was developed, based on the results of this experiment. The conceptual model presented included an increase in discomfort with vibration magnitude as well as an increase of discomfort with duration of exposure.
