Unverified85% confidenceCautionTime unknown
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

Unverified对低频噪音（如货车轰鸣、低音炮、变压器嗡嗡声）几乎无能为力，双层中空结构对低频段衰减极为有限，有低频噪音困扰应选夹胶玻璃方案89% 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88% similarUnverified对低频噪音（如大货车、火车轰鸣、低音炮）效果有限，低频隔音需要夹胶玻璃或更复杂的多层结构，双中空结构主要优势在中高频段88% similarUnverified低频噪音（如机器轰鸣、电梯运行、低音炮）比高频人声更难隔绝，单纯换隔音门效果有限，需配合墙体隔音、隔音窗才能形成完整隔声系统84% similar
