Abstract

The invention relates to the method of producing sound- absorbing blocks in which a plurality of tubular polygonal parallel inserts are placed in a mould, the inserts having, at regular intervals, a series of apertures between which they fit at corresponding tubular polygonal inserts arranged in an orthogonal direction. A mixture for making blocks is cast, and when consolidated these inserts are withdrawn and a central cut is made in a plane parallel to the bottom of the mould, producing blocks with a rusticated surface. <IMAGE>
