The present study deals with the human perception of automotive BSR(Buzz, squeak, and rattle) noises. Sound pressure level has been used for measuring noise levels of different sources, however, there have been debates on the usefulness of the sound pressure level(SPL) to represent the human perception, especially for categorization purposes. Based on the collected sound sources obtained from fields and laboratory tests which then systematically categorized and moderated, the human response could be obtained through jury evaluation. Correlation between the human perception and objective metrics such as dBA (mean and L-10) and loudness (ISO mean and N-10) for differently categorized sounds are presented. Peak frequency, SPL, and event duration are considered for sound source categorization. According to the present study, intermediate frequency squeak noises and impact noises were more susceptible to human disturbance.
