Substation Transformer Noise Levels by raul_bsu is a document available to read on EtoBox.

Typical noise levels from equipment in a power substation range from 60 to 80 dBA, with transformers being the main source of noise. Complaints about noise are more common for substations with transformer sizes between 20-150 MVA within 170-200 meters. The rate at which transformer noise attenuates with distance depends on the characteristics of the transformer. In the near field close to the transformer, the attenuation is very small, while in the far field the attenuation is approximately 6 dB for every d
