Noise measurement on transformers, substation boundary and noise-sensitive buildings of a 110kV indoor substation was carried out. The 1/3-octave band spectrums in different areas were analyzed, and was found that the transformer noise affects the substation boundary and noise-sensitive buildings. Taking ventilation and noise reduction into account, this paper proposes a noise control program. With this program executed, the noise reduction of north side of substation boundary is more than 9 dB in the daytime, more than 14 dB in the nighttime while it is 7.9 dB in the daytime, 8.6 dB in the nighttime in the residential building on the west side of the substation.
