| Abstract: |
| 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. |
