Abstract
A sound attenuator for transformers comprises a rigid plate fixedly attached to a resilient mass. The sound attenuator is attached to the transformer outer wall in the vicinity of highest sound production. The characteristics of the metal plate and the resilient mass are chosen to produce acoustical radiation out of phase with the noise emitted at the transformer wall surface.
