The conclusions are drawn by analysis : the sound insulation performance of structure is improved by using flexible viscoelastic materials ; otherwise it is complicated to sound insulation for incidence angles and the thickness of materials ; for multi - layered compound structure, it is important to choose flexible viscoelastic materials as external rubber, which can gain good insulative effect
分析表明：軟質阻尼材料能明顯改善結構的隔聲性能；相對來說入射角度和材料的厚度對隔聲性能的影響比較復雜；而對于多層復合結構而言，面層橡膠的選取尤為重要，一般採用軟質橡膠材料來得到大的隔聲量。
