| Abstract: | The formulas for the transformation of sound levels between linear spectrum and multiplex frequency band,or among various multiplex frequency bands,are derived and the corrected value is calculated.The above formulas are used in theM standard spectrum and the three-section standard spectrum for evaluating the tread patterns' noise to provide a simple calculating tool and line-up comparison for analyzing the frequency spectrum of tread patterns' noise. |

| Keywords: | tire tread patterns' noise frequency band conversion evaluation criteria |
