ActiveAcoustics―Measurement of sound insulation in buildings and of building elements using sound intensity―Part 2: Field measurements
声学 建筑和建筑构件隔声声强法测量 第2部分：现场测量
Application Summary AI generated
This standard specifies the use of sound intensity measurement techniques for evaluating sound insulation in buildings under field conditions. It is applied by acoustical engineers and building inspectors to measure the actual in-situ sound reduction between rooms or across building elements like walls and floors, accounting for flanking transmission and real-world installation effects. The standard is critical for verifying compliance with building acoustic regulations and for diagnosing noise problems in completed structures.
