    Abstract: Panels having enhanced, customizable acoustical characteristics are provided that comprise a core panel (12) of metal or bonded materials and that have an undulating exposed surface, with the size of the undulations being dependent on the wavelength of the sound intended to be diffused. The surface of the panel may also be provided with irregularities, such as perforations, for sound absorption, with the size, shape and layout of the irregularities being dependent on the wavelength of the sound intended to be absorbed. The core panel is combined with a backing matt (14) of bonded materials that is compression molded so as to have a density lower and thickness greater than that of the core panel. A film facing (16) may be applied to the front surface of the core panel, as well as an optional sound-transparent, aesthetic finish (18). The film facing may comprise a non-porous coating for high frequency diffusion applications.

    Abstract: A supporting material in the form of sheet or roll, constituted of a cellulosic material, or a rolled section in paper treated with a solution, or a rolled section in melaminic paper, or a mixture of leather regenerated materials or derivatives thereof, or cardboard or cardboard fiber, or needled fabrics, or synthetic or natural rubber, or foam made of reticulated polyethylene with closed cells, or foam made of reticulated polyethylene with closed celle, or natural or synthetic leather, or non-woven fabric, neoprene, masonite, recycled polyethylene, nylon, Lilion3, Tyvec3, polyester or a net made of synthetic material, or cork or wood, or a coagulated material, or felt, or foamed polyurethane, foamed polyethylene, foamed polystyrene, or a perspiring material, or an agglomerated stone-like material, is coupled to a covering layer made of polyethylene or Surlyn3, whereby the upper surface of the covering layer is embossed, in such a way as to imitate another material. This composite material has a high surface resistance, thus being particularly suitable for a plurality of applications; furthermore, said composite material is non-toxic and thus usable for contacting the skin for a long period of time.
