Abstract：The causes and propagation modes of low‑frequency noise in 10 kV substation are discussed,

and the relevant requirements of national codes for noise limitation are summarized. The influence range of low‑frequency noise in 10 kV substation is analyzed in combination with noise control cases. It is suggested that importance should be attached to the low‑frequency noise within the projection range of 10 kV substation buildings. 

Key words：10 kV substation;substation site selection;low‑frequency noise;noise limits;noise reduction measures;vibration propagation;airborne propagation;control cases 

摘　要：阐述10 kV变电所低频噪声的产生原因及传播方式，综述国家规范针对噪声限制的相关要求。结合噪声治理案例，分析10 kV变电所的低频噪声影响范围，建议重视10 kV变电所建筑投影范围内的低频噪声问题。
