Noise pollution is an important issue in modern societies. Power transformers are a significant contributor to this unwanted ambient noise. Till two decades ago, the noise produced by transformer was not attached any importance in public life. However, of late it is attracting attention as a result of the general public’s growing concern about the environmental noise pollution. During normal operation, transformer produces characteristic hum, the magnitude of which increases with increase in its capacity. This paper discussed about influencing factors for noise generation like Flux density, core construction, core construction, Building Factor, Core clamping & Pressure, winding diameter, cooling fans and etc. Standards IEEE, IES & NEMA TR-1 for noise measurement procedure, it depends on the distance between the measuring surface and noise radiating surface by using of noise level meter.
