窗帘的隔音主要靠克重和褶皱空气层，克重≥250g/㎡且褶皱倍数（褶皱比）达到2.0以上才有明显吸音效果；单纯遮光布对高频噪音只有3-8分贝衰减，临街隔音应优先换双层玻璃而非依赖窗帘

Unverified窗帘隔音主要靠克重与褶皱空气层，克重≥350g/㎡且褶皱倍数(布料宽/窗宽)≥2.0才有明显降噪，实测仅降3-8分贝，无法替代隔音窗94% similarUnverified窗帘的隔音主要靠克重和悬垂厚度：克重≥350g/㎡的厚绒布可降噪约5-8分贝，仅对高频噪音有效；对交通低频噪音几乎无用，隔音需靠双层玻璃而非窗帘94% similarUnverified隔音靠克重和层数而非遮光率，克重≥350g/㎡的植绒或棉麻加绒帘才有明显降噪(约3-8分贝)；临街噪音需配合中空玻璃，窗帘单独降噪效果有限94% similarUnverified隔音主要靠克重和厚度，克重≥250g/m²的加厚绒面/植绒窗帘可降噪约5-8分贝，但窗帘对隔音贡献有限，临街噪音困扰应优先解决窗户密封和加装隔音条，勿指望窗帘完全隔音94% similarUnverified窗帘隔音主要靠面料克重和悬垂厚度，克重≥300g/㎡且做1.5-2倍褶皱才有明显吸音效果，但窗帘对低频噪音（车流、空调外机嗡鸣）几乎无效，隔音需靠中空玻璃93% similar
