Abstract
A plurality of acoustical absorption elements are mounted in a two-dimensional spaced array on an acoustically reflective surface of an machinery enclosure, in such a manner as to expose portions of the reflective surface between neighboring elements. The elements are preferably of a substantially standard size and shape in order to enhance production and inventory efficiency, although materials of various thickness may be provided to accommodate tuning for specific frequencies to be absorbed.
