Abstract
In determining presence/absence of abnormal sound occurrence in a test object such as a vehicle immediately after completion of vehicle assembly, sound data of the test object during running on a rough test track is recorded and resolved into multiple frequency bands by time unit. The sound data resolved into multiple frequency bands by time unit is compared among the multiple frequency bands and correlation coefficients matrix values indicating strength of correlation between the multiple frequency bands n are calculated. Presence/absence of the abnormal sound occurrence is finally determined based on the calculated correlation coefficients matrix values.
