[origin: US6057254A] PCT No. PCT/EP96/05150 Sec. 371 Date Jul. 9, 1998 Sec. 102(e) Date Jul. 9, 1998 PCT Filed Nov. 22, 1996 PCT Pub. No. WO97/25491 PCT Pub. Date Jul. 17, 1997A dimensionally stable and fireproof acoustic panel includes an underlying panel covered on one or both sides by a cover panel. The underlying panel can be produced with a cover layer on the interior side thereof. The cover layer is composed of two layers, a coarse-pored stabilizing intermediate layer which in turn is covered by a second, fine-pored outer layer, both of which are bonded to one another and to the underlying panel by a matrix of adhesive material.
