Development and Validation of a Masking System for Mitigation of Low-Frequency Audible Noise from Electrical Substations

2021-07-16

Abstract excerpt

Low-frequency audible noise generated by the magnetostriction effect inherent to the operation of power transformers has become a major drawback, especially in cases where the electrical substation is located in urban areas subject to strict environmental regulations that imposes sound pressure limits, differing for day and night periods. Such regulations apply a +5 dB penalty if a tonal component of noise is pres...
