For basic soundproofing, 1 inch pyramid foam provides moderate sound control on walls or ceilings, especially ones not parallel to the floor. This product is best for when absolute sound deadening is not required, but moderate deadening is desired. 1 inch pyramid foam is most effective on mid-to-high frequency ranges.

Pyramid vs. Wedge Absorption
To create the pyramid style, this foam must pass through our machine twice, resulting in a higher cost than the wedge for a more visually pleasing product. With less overall mass than our wedge foam, it provides about 76 percent as much absorption than the wedge, but has a better diffusion rate.
