This paper proposes a new measurement standardization procedure to measure and quantify the acoustic noise produced by power transformers in audio and video equipment under normal and adverse mains conditions. These conditions and the physical mechanisms that cause the noise are discussed. A new measurement setup and units are proposed to measure and quantify the transformer noise. Examples of measurements of four transformers are given for comparison and illustration.
