Understanding opinion-forming processes during on-road evaluations of whole vehicle sound quality

To improve the effectiveness and efficiency of decision making during vehicle development programmes, new interactive NVH simulation tools have been introduced. For their optimum use during the target setting of NVH attributes new methodologies need to be established. A valuable step in achieving this is to further understand opinion forming processes during on-road appraisals. To achieve this however new approaches to capture the events of an appraisal are needed.
