摘要

To analyze the abnormal noise with unsteady characteristics in a bus';s transmission, a Moore instantaneous loudness model was established based on standard of ANSI_S3.4 2005, and a Zwicker loudness model was cited for validation contrast, then the instantaneous loudness model was applied to a vehicle interior noise identification and its quantitative evaluation. The results showed that the calculation accuracy and instantaneous specific loudness of Moore model are better than those of Zwicker one, Moore instantaneous loudness model is helpful for noise source identification and its mechanism analysis in an unsteady process, and it';s feasible to use Moore loudness for noise quantitative evaluation.
