针对多孔沥青混合料吸声预测模型类型分散、参数获取方法不统一及结构信息利用不足的问题，本文系统梳理了半经验阻抗模型、等效流体模型、孔弹性模型和孔隙尺度数值模型。阐述了吸声系数、特性阻抗、复波数和表面阻抗之间的计算关系，比较了Delany–Bazley、Miki、Johnson–Champoux–Allard（JCA）、Johnson–Champoux–Allard–Lafarge（JCAL）及Biot模型的输入参数、物理假设和适用范围。分析结果表明，半经验模型参数少且计算效率高，但对多孔沥青非均匀大孔结构的适应性依赖再标定；JCA和JCAL模型能够通过孔隙率、流阻率、曲折因子及黏性和热特征长度描述空气—孔壁耗散，是连接三维孔隙结构与吸声频谱的主要路径；Biot模型可计入骨架振动，但参数识别和计算成本较高。结合CT三维重构、传输参数数值计算和阻抗管反演建立多源参数体系，并开展独立验证与不确定度分析，可提高模型在配合比设计和服役性能评价中的可靠性。
