Research Objective The sound quality of automobiles has drawn much attention, and sound quality of door slamming will impact psychological tendency of customers during vehicle purchase. Therefore, this chapter provides test and evaluation method for sound quality of door slamming and its improvement measures. Methodology For test method, the proper position of door slamming force acting location, velocity range of door slamming, consistency of slamming force each time and layout of microphone are the factors which are taken into account. For evaluation method, factors such as pulse convergence time, sharpness, loudness, duration of low-frequency residual noise and high-frequency noise are considered. Thirdly, for optimization for door slamming, subjective evaluation, objective analysis and exclusion method are applied. Results Through optimization of vehicle sealing, design of door latches, layout of weather strips, return spring of door handle, and contact location between handle and base, the door slamming sound quality can be improved. Limitations of this study CAE simulation analysis should be carried out at all stage. What does the chapter offer that is new in the field including in comparison to other work by the authors: A series of measures to improve the door slamming sound quality are introduced in detail. Conclusion Evaluation method for the sound quality is presented, and practical improvement measures are proposed.
