Abstract

This invention deals with the method of manufacture of a secondary residual sound diffusion processor by making molds of identical specifications with light-steel ceiling frames for the processor before injection of light plastic material (PVC) for forming the flange on the circumference before painting for a rough surface and diffusion of the space, as a light-weight yet formulated second residual sound diffusion processor of light-weight ceiling frame.
