Abstract
This paper discusses the design and development of a high-attenuation field-applicable acoustic enclosure for large power transformers, based in concept upon the "Field Incidence Mass Law" from the field of acoustics. Free-standing and form-fitting, enclosures of this type have been designed to provide noise reduction in the order of 15 to 20 db (decibels), in addition to other advantages inherent in a near-total enclosure.
