With a passenger car of a self-owned brand taken as a research platform,the poor door closing sound quality was tested,evaluated,diagnosed and optimized.The main reasons for the poor sound of the prototype vehicle were found out by subjective evaluation and objective tests.The independent operation method was adopted to optimize the main factors affecting the sound quality of the door,the contribution of each factor to the loudness and sharpness of the sound quality of the door was analyzed through objective testing,and the subjective and objective evaluation of each optimization scheme was conducted.The results show that the multi-measure integrated optimization scheme significantly improves the door sound quality,the subjective evaluation value increases by 31.9％compared with the one before optimization,and the objective test result is better than that of the benchmark car.
