  • This paper presents the objective method to evaluate the subjective evaluation of the pulling sound of the seat belt. The physical quantification is required to objectively evaluate the subjective response of the pulling sound. This is called the “sound quality metric.” The sound quality metric should be correlated with the subjective rating of the pulling sound. In this paper, not only is the sound quality metric extracted from the measured interior sound when a passenger pulls the seat belt but also the subjective evaluation is performed for the pulling sound of the seat belt in the 18 vehicles. The pulling sound index is developed through a linear regress analysis of the sound quality metric and the subjective rating. The developed index is used for the objective evaluation of the subjective evaluation of the pulling sound of a seat belt with after modifications of seat belt components.
