| 中文摘要: |
| 介绍轮胎室外通过噪声的室内测试方法。基于室内声学原理，借助可控温的滚动阻力实验室，在室内转鼓上进行轮胎噪声测试。通过对比室内与室外轮胎噪声测试条件，得到室内与室外噪声转换公式，进而求出室外通过轮胎噪声。该测试方法简便、实用，测试结果稳定、可靠。 |
| 英文摘要: |
| The indoor testing method for the tire outdoor passing-by noise was introduced.Based on indoor acoustics principles，the tire noise testing was conducted on the indoor drum using the temperature-controlled rolling resistance laboratory.By comparing the testing conditions of indoor and outdoor tire noise，the conversion formula between indoor and outdoor noise was obtained，and then the tire outdoor passing-by tire noise was calculated. The testing method was simple and practical，the testing results were stable and reliable. |
