| 中文摘要: |
| 分析了人听觉系统的特性和轮胎噪声的特点，阐述了用Zwicker 响度替代A声级作为轮胎噪声客观评价指标的优点，并对Zwicker响度和A声级两种客观评价指标进行对比试验。结果表明，在评价精度要求不高时可以采用A声级等常规指标进行粗略比较，而Zwicker 响度评价结果和主观评价结果能较好吻合，宜作为轮胎噪声客观评价指标。 |
| 英文摘要: |
| The characteristics of human hearing system and the features of tire noise are analysed，the benifits from the replacement of Zwicker sound pressure level for sound level A as the criterion of objective tire noise evaluation are described，and a comparative test between two creteria，i.e.Zwicker sound pressure level and sound level A is carried out. The results show that the conventional criteria，such as sound level A is suitable for the less accurate evaluation ；and the Zwicker sound level is a suitable criterion for objective tire noise evaluation because its result is well fitted to that of subjective tire noise evaluation. |
