AbstractThe noise produced by substation power transformers constitutes a special acoustical problem for two reasons: a) the most important components in the noise are at 120 cycles per second and its lower harmonica, a region for which conventional acoustical materials are inefficient;b) to facilitate cooling the transformers they are usually only partially enclosed, so that any acoustical treatment introduced should be weatherproof. The object of this study was to develop sound absorbing systems to meet these special requirements.
