需要高隔声的影音室、录音室不应仅用单层轻钢龙骨隔断，即使填岩棉也难超50dB，需采用弹性隔声条+双层错缝石膏板+减振龙骨的组合墙体系统

Unverified隔音靠'质量定律'——单靠一层隔音毯的隔声量约5-10dB，远达不到墙体本身的效果；要显著隔音需构建'龙骨+隔音毡+石膏板+隔音棉'的复合结构，隔音毯单独悬挂只是辅助手段77% similarUnverified吸音板厚度与低频吸收能力正相关但占用空间大：薄款美观省空间但只能吸中高频，厚款吸全频但侵占房间体积，家用影音室建议25-50mm折中77% similarUnverified改善直播/录音室内回声选聚酯纤维吸音板，NRC≥0.8、厚度9mm即可；若为影音室低频驻波问题，需在墙角配置厚度≥50mm的低频陷阱，薄板对低频无效76% similarUnverified音画质要求高选带独立Soundbar或多单元音响的高端型号，超薄壁挂款为极致外观牺牲音腔空间，低音单薄需另配回音壁76% similarUnverified隔音（挡声）与吸音（除混响）不能兼得于单一薄板：低频隔音靠'质量定律'需要重且厚的结构，而吸音靠疏松多孔材料，两者材料特性相反，实际项目需分层组合而非依赖一种板76% similar
