Abstract
The sound-absorbing panel in question has an inner core 1 consisting of a pair of sheets 2, 3 of textile fibre F, natural or artificial, each having a different thickness and density by volume; each of the sheets 2, 3 can be fixed parallel to the other on one of their corresponding surfaces 5 of greater extension in such a way as to form a true mattress structure 4 having a differentiated sound absorbency; a covering and joining element 5 for the mattress is also provided, and consists of a layer of fireproof fabric 6 positioned and fixed on the outer surface formed by the pair of sheets 2, 3. (Fig. 1). <IMAGE>
