Abstract: Sound Insulation calculated by experimental formulas can servers for noise prediction analysis. The noise insulation property in low frequency is ensured by experimental formulas and also lots of data for sound insulation test during sea trial to be improved by increase the depth of air space layer. It serves as reference for design and installation of wall panels on Offshore Platform.

摘要： 通过讨论舾装板结构特点及其隔声性能，得到海洋平台常用舾装板结构的隔声经验值，为海洋平台整体噪声预测分析提供一定的参考。比较大量的实验室测量数据和实船测试数据，可通过加厚双层舾装板的空腔夹层以提高其低频隔声性能，大大节约生产成本。可为舾装设计安装提供参考。
