ActiveAcoustics—Calculation of sound attenuation during propagation for electrical converter station—Engineering method
声学 换流站声传播衰减计算 工程法
Application Summary AI generated
This standard specifies an engineering method for calculating the attenuation of sound as it propagates from electrical converter stations, which are key components in high-voltage direct current (HVDC) power transmission systems. It is applied by acoustic engineers and environmental planners to predict noise levels at surrounding residential or sensitive areas, enabling the design of effective noise control measures during station planning and construction. The standard is used specifically in the power industry for environmental impact assessments and compliance with noise regulations.
