Wheel/rail noise of the high-speed slab track on concrete bridge and that of the urban elevated supporting block track are predicted respectively. Noise of the slab track, compared with that of the ballasted track, is more severe. The noise of the slab track is about 6.2dBA higher than that of the ballasted track for the receiver nearby the rail, and about 3.5dBA higher than that of ballast track for the receiver

对降低高速铁路桥上板式无碴轨道及城市轨道交通桥上支承块式无碴轨道轮轨噪声的技术措施进行了研究，包括：(1)分别就板式轨道和支承块式轨道结构参数的低噪声设计原则进行了研究；(2)对几种典型的新型轨道用吸声材料的降噪效果进行了分析，结果表明降噪效果显著；(3)就声屏障高度、位置、形状以及声屏障内侧敷设吸声材料对降噪效果的影响进行了分析，结果表明：声屏障越高、越接近轨道，降噪效果越好；声屏障内侧敷设吸声材料，可降低钢轨近旁噪声2.0～3.0dBA，可降低近地面噪声约1.5～2.0dBA
