VINYL COVERED SOUND ABSORBING STRUCTURE

摘要

VINYL COVERED SOUND ABSORBING STRUCTURE The base structure of a fibrous material has on one face thereof a plurality of acoustical perforations. Positioned over this perforated face is a vinyl layer having a plurality of apertures therein, the apertures of the vinyl being in number much greater than the number of perforations in the base structure. The apertures in the vinyl sheet not all being in alignment with the perforations of the base structure, but the perforations of the base structure having a substantial number thereof in alignment with the apertures in the vinyl structure whereby an acoustical sound absorbing structure is formed.
