ActiveAcoustics—Measurement of noise emitted by railbound vehicles
声学 轨道机车车辆发射噪声测量
Application Summary AI generated
This standard specifies measurement methods for noise emitted by railbound vehicles, including locomotives, passenger cars, and freight wagons, under defined operating conditions. It is applied in China for type testing and noise certification of railway vehicles to ensure compliance with environmental noise regulations. The standard is used by manufacturers and testing bodies in the rail transport industry to quantify exterior noise levels during stationary, accelerating, and pass-by scenarios.
