摘　　要：推导线性谱声压级、倍频带声压级以及各倍频带声压级之间的转换公式 ,计算出修正值。将三者之间的变换关系应用到轮胎花纹噪声评价M标准线和三段标准谱线中 ,为轮胎花纹噪声的频谱分析提供了简化运算工具和排队比较方法。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.

关 键 词：轮胎 花纹噪声 频带转换 评价标准
