The electromagnetic shielding of an enclosable building structure is provided by applying a shielded covering to overlay optical openings in the building structure. The shielded covering comprises a metal-coated woven substrate and a shielding coupling. The metal-coated woven substrate has a woven substrate and a metal coating. The woven substrate may be organic and comprise threads of intermingled fibers such as silk fibers. The metal-coated woven substrate may also have a protection feature such as transparent resin, of barriers of glass or transparent polymeric material. The shielded coupling connects the shielded covering to other shielding components of a shielded building structure to preserve shielding continuity over the interface between shielding components.

The present invention relates to the acoustic metamaterial structural unit with the function of soundproof, flow-passing and heat-transferring enhancement, which comprises a frame, a constraint placed in the frame and a piece of membrane covering at least one surface of the frame; both the frame and the membrane are respectively placed at least one hole. Besides, the present invention also provides the acoustic metamaterial composite plate and the composite structure constructed with the acoustic metamaterial structural unit; the method for adjusting the frequency and the assemble method. The present structural unit possesses better soundproof property than the routine perforated plated or micro-perforated plate in broad operating frequency. And also the enough heat flow, gas flow or fluid flow can pass through smoothly. The diffuse efficiency of the heat energy of the mediums on both sides of the hole is increased by the vibration of the self-structure under the excitation of the soundwave and further the efficiency of heat exchange is accelerated. The method for assembling the acoustic metamaterial composite structure with the acoustic metamaterial structural units is simple. The operation performance is steady.

An acoustical panel apparatus includes a laminate panel substrate that is receptive to ink printing operations. The substrate may be provided with folding grooves to form an apertured base, a sidewall, and an inner wall which together define a receptacle. An acoustical tuning body is positionable at the receptacle to attenuate at least one of sound transmissions and sound reflections from sound passing through the apertures in the base. A mounting bracket is attached to the panel to secure the acoustical tuning body at the receptacle and for mounting the panel substrate to a wall or ceiling.

Electromagnetically shielding an enclosable structure having a floor, walls, a ceiling, and at least one closeable opening by applying a shielding wallcovering to at least a portion of one of the walls and applying a second type of shielding material to at least a portion of the enclosable structure, wherein the second type of shielding material differs from the shielding wallcovering. The shielding wall covering is wallpaper comprising a metal-coated broad good and a resin. Other types of shielding material may include a transparent, shielding window covering such as NiCVD coated screen of woven silk fibers; shielded flooring such as a layered combinations of Kevlar non-woven as a base layer, nickel-coated non-woven layers, and a PCF toughened polymer; and a transition shielding strip made of a base layer of the shielding wallpaper with a PCF toughened polymer coating over a portion of the strip.
