| 中文摘要: |
| 提出一种简易的轮胎噪声实测谱和仿真谱的解读方法。首先将轮胎噪声谱分为低频段、中频段和高频段，再根据不同频段轮胎噪声的声能分布情况，得到轮胎总噪声声压级在各个频段所占的比例，最后通过评分公式进行计算，判断是否为低噪声轮胎。该方法可弱化主客观评价不一致的现象。 |
| 英文摘要: |
| A simple analysis and evaluation method of the measured and simulated tire noise spectra was proposed.First，the tire noise spectrum was divided into low-frequency band，mid-frequency band and high-frequency band，and then according to the tire noise distribution in different frequency bands，the proportion of sound pressure level in each frequency band was obtained.Finally the tire noise score was calculated by using a rating formula，and the score was used to rate whether the tire was low noise tire.This method could reduce the inconsistency between subjective and objective evaluation. |
