| 中文摘要: |
| 研究轮胎噪声室内转鼓法与室外滑行法测试结果的相关性。结果表明：两种测试方法对不同方案轮胎噪声测试结果趋势一致；两种方法测试的声压级差值与理论计算值的误差均在1 dB（A）之内；两种方法测试结果的1/3倍频频谱在中频段（800～1 600 Hz）有一定的相似性。 |
| 英文摘要: |
| The correlation between the test results of laboratory drum method and coast-by method was investigated.The results showed that，the trends of the test data for different schemes of these two methods were consistent.The error between the sound pressure level difference value of two methods and the theoretical calculation was within 1 dB（A）.The 1/3 octave bands of the two test methods was certain similarity in the middle frequency band（800～1 600 Hz）. |
