Abstract
An acoustical wall panel includes an elongated sound absorbent board faced with a needle-punched non-woven fabric provided with a woven scrim backing and having linear ribs extending longitudinally of the panel. Such panels are mounted by generally H-shaped splines concealed by the panels. The lofted texture of the fabric and the linear ribs help conceal a seam between two panels.
