Abstract In the current paper, which deals with the noise pollution excited by
distribution transformers in the living area, a comprehensive treatment scheme
is put forward for the purpose of reducing the sound pressure level emitting into
the environment. In accordance with the associated test standard, the sound pressure levels of distribution transformer and surrounding environment are not only
tested but analyzed as well. The measurements were carried out with the frequency analysis of the 1/3 octave resolution, with the center frequencies at
125 Hz, 250 Hz, 400 Hz, and 500 Hz. As illustrated, on the… More >
