UpcomingAcoustics—Field measurement of sound insulation in buildings and of building elements—Part 3: Airborne sound insulation of facade elements and facades
声学 建筑和建筑构件隔声的现场测量 第3部分：外墙和外墙构件空气声隔声
Application Summary AI generated
This standard specifies field measurement methods for determining the airborne sound insulation of building facades and their elements, such as windows, doors, and walls. It is applied in construction and building acoustics testing to verify that completed buildings meet regulatory sound insulation requirements for external noise protection. The standard is used by engineers and inspectors during on-site acceptance checks in residential, commercial, and public buildings.
