Abstract
Sound power level is a unique feature of large power transformers used to estimate noise effects on the environment. It is determined from the direct measurement of the sound pressure level or sound intensity level. In the paper, procedures for reproducibility estimation of sound power level and procedures for estimation of uncertainty of sound pressure level and sound intensity level are given for point-to-point and walk-around test procedures.
