如主要问题是低频道路噪音，贴膜投入产出比极低；应优先升级密封条、加装隔音棉/吸音棉，或换装原厂夹胶玻璃，隔音膜只作为中高频的补充方案

Unverified隔音效果差主要因低频漏声时，单纯增加玻璃层数（如换三玻两腔）性价比低，应优先排查密封条老化和墙体缝隙84% similarUnverified隔音贴膜对低频噪音（重卡、地铁震动、低音炮）几乎无效，因低频靠空气传播能量强，需靠玻璃增厚或双层中空结构解决，贴膜只擅长中高频84% similarUnverified低频噪音（如变压器嗡嗡声、低音炮）效果有限，中空玻璃对低频隔音存在共振短板，夹胶玻璃低频表现优于中空但仍难完全消除83% similarUnverified临街低层(≤6层)且主噪声为中低频(货车/施工)时，贴膜几乎无效，应优先更换双层中空玻璃或加装第二层内窗，贴膜仅对高频噪声(尖锐声)有轻微改善83% similarUnverified单层隔音毡的隔音效果有限，必须与石膏板、隔音棉等组合成多层结构才能实现显著降噪，单独贴一层毡对低频噪音改善不明显82% similar
