自動車の音質評価データべースの作成(Part I 乗り物の音色・音質改善技術,特別オーガナイズドセッション「音色・音質設計技術〜開発者と利用者・第三者を繋ぐ」,振動・騒音改善技術)

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.
