| 摘 要： | 介绍了车内异常噪声辨识的心理声学分析方法；指出基于心理声学的分析方法考虑了入耳听觉特性。能够定量地反映不同噪声的主观感受差别，较好地符合异常噪声辨识要求。在试验测试基础上，从响度、粗糙度、尖锐度和抖动度等方面对车内噪声品质进行了对比分析。

| Abstract: | The psychoacoustics analysis methods for identifying abnormal interior noise of a car are presented.It is pointed out that psychoacoustics analysis methods take human hearing characteristics into account and can reflect quantitatively the subjective feeling discrepancy for different noises,thus better meeting the requirements of abnormal noise identification.Based on experiments,the qualities of in-car noise are compared in terms of loudness,harshness,sharpness and fluctuation. |
