Abstract

The panel of sound absorbing material (1) has a regular array (5) of tapered holes (3). Each hole is wider at its front side (4) than at its rear side than at its rear side which is adhered to a substrate made of sound-absorbing material. The sides of the hole (10) may be convex, concave or S-shaped. The holes may be shaped to correspond to different resonant frequencies.
