Abstract

A plate-shaped sound-absorbing element is composed of a synthetic resinous foam material, e.g. polystyrene, with closed pores, the element having been pierced with a plurality of needles to form true channels therein extending perpendicular to the plane of the element. The piercing may extend either only partly or right through the thickness of the element. The elements may be 8-12 mm. in thickness and pierced by 300,000 to 500,000 needles per square metre of their surface area, the needles being 0.6-1.4 mm. in diameter and between 60 and 100 mm. in length. The surface of the plate may have a plurality of annular depressions therein formed by the application of a hot embossing die which may be coated with wax as an antisticker. A series of such elements may be applied to surfaces such as walls, ceilings and plaster to render rooms sound-absorbent.
