Abstract

A full scale aero-acoustic wind tunnel test on a 4-door middle class sedan has been applied to determine contributions of major seal components to interior leak noise with "buildup" scheme. Results using psychoacoustic metrics loudness and articulation index (AI) were also compared. The results show that seals for doors, rearview mirrors and side windows are the most important leak noise sources for that vehicle. While selecting the method of analyzing seal contributions to interior noise, besides A-weighted sound pressure level (SPL), quality metrics such as loudness and AI should be considered as well.
