Abstract
This paper describes a large-scale automotive sound quality evaluation database created by the JSAE Sound Quality Evaluation Research Technical Committee. This database was created by conducting subjective evaluation tests under controlled conditions and using common procedures. It involves the subjective evaluation data for the interior sounds of accelerating gasoline passenger cars by 101 Japanese test subjects, and for the exterior sounds of diesel trucks at idle by 143 Japanese test subjects. Moreover, the subjects' profiles data (gender, age, sound quality specialists, and so on) are included. We can carry out various analyses on automotive sound quality and some effective results for improvements of sound quality can be obtained by using this database.
