Abstract (en)
A sound absorbent panel (10) consists of a sheet (12) of wood-based material comprising a core of compressed material (10) and balanced veneers (18,20) on two sides, and at least one sheet (14) of non-woven fabric made of sound absorbent material glued to one side. An improved sound absorbent effect superior to the effect that can be obtained with the two separate elements is achieved. <IMAGE>
