隔音门门芯密度越高越重隔音越好：实木门芯或多层复合(如岩棉+石膏板+钢板)隔音优于蜂窝纸/空心门，单扇门重量达到25-40kg以上才具备真正隔音能力

Unverified门芯材料隔音排序：多层实木/密度板复合＞岩棉+隔音棉填充＞纯蜂窝纸；蜂窝纸门芯轻便廉价但隔音仅25dB左右，重量＜15kg的室内门普遍是蜂窝结构86% similarUnverified门芯填充材料决定隔音下限：纸质蜂窝（模压门）几乎无隔音，实心刨花板/密度板约25-28dB，专业隔音棉+多层复合结构可达35dB以上，铅板/复合钢结构入户门可达40dB82% similarUnverified追求隔音应选克重≥300g/㎡、面料厚重且带绒毛结构（如植绒、雪尼尔）的窗帘，并做2-2.5倍褶皱打褶，褶皱越密隔音吸声越好；单薄遮光布几乎无隔音作用80% similarUnverified隔音需要克重≥300g/㎡的厚重面料（如高密植绒、多层复合），克重越高隔音越好但也越重，300g以上需搭配承重更强的罗马杆或双层轨道，普通细杆易变形79% similarUnverified追求隔音选克重400-600g/㎡的植绒/雪尼尔面料+双开落地款，褶皱比2.0以上（即窗帘用料宽度为窗宽2倍），褶皱越密隔音吸声越好79% similar
