噪音主要从门窗缝隙泄漏，先做密封条（门缝D型/P型硅胶密封条+门底挡风条）可降5-10dB，成本极低且见效最快，应优先于墙面改造

Unverified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82% similarUnverified隔音效果高度依赖安装密封质量，窗框与墙体之间的发泡填充、密封胶条的完好程度对最终隔声量影响很大，安装不到位可能损失5-10dB80% 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80% similarUnverified婴幼儿房门缝隔音选EVA/硅胶密封条时，降噪能力实际仅3-8dB，主要作用是阻挡门缝漏音（如走廊脚步、说话声），无法隔绝隔壁装修等结构传声；若追求整体降噪≥20dB需配合门板加厚或吸音棉，单靠门贴不够79% similarUnverified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77% similar
