Unverified90% confidenceSolutionTime unknown
门缝和窗缝是隔音最大漏洞：一扇实心门底部1cm缝隙可让隔音量下降10dB以上。先用密封条封门窗缝、装门底密封条，性价比远高于给整面墙做隔音

Unverified声音走漏洞：门缝、窗缝、插座孔、管道穿墙处是最大漏音点，做隔音先用密封条封门窗缝、发泡胶封孔洞，性价比远高于整墙改造85% similarUnverified声音是从最薄弱处泄漏的：即使墙面隔音做到位，门窗缝隙、空调孔、插座盒会大幅降低整体隔声量；需同步处理门缝密封条、更换隔音门/双层玻璃窗，否则墙体隔音投入事倍功半83% similarUnverified隔音门缝改造标准路径：判断噪音来源（缝隙or门板本身）→缝隙问题用加厚硅胶密封条封四周→门底用双层刮条门底条→若门板轻薄需另加吸音处理，密封条只能解决缝隙传声约30%的噪音80% similarUnverified门缝、窗缝的缝隙漏音占整体噪音的很大比例，遵循'木桶效应'：花钱贴满整面墙的隔音毯，却不处理门底缝隙，隔音效果几乎归零。应优先用门底密封条+隔音门帘处理缝隙79% similarUnverified吸音效果好坏受安装方式影响极大：窗帘应超出窗框两侧各20-30cm并落地拖地5cm以上，形成封闭空气腔，否则声音从缝隙泄漏79% similar
