| 中文摘要: |
| 在混响室内测试了轿车轮胎的噪声声级。讨论了不同结构、规格、花纹的轿车轮胎在不同气压、负荷、速度下的噪声声级变化。研究表明，混响室内的噪声测试可以辨别不同轮胎的噪声声级；花纹形式、节距数量及节距排列顺序严重影响轮胎的噪声声级。 |
| 英文摘要: |
| The noise level of passenger car tire was measured in a reverberation laboratory. The change of the noise level of passenger car tires with different structure，size and tread pattern was investigated at different inflation pressure，load and speed. The results showed that the noise level of different tires could be evaluated through the noise measurement in the reverberation laboratory；the pattern shape，the number and the order of pitches had great influence on the noise level of tire. |
