Noise screening hood or cubicle sections - have sheet metal coating both sides of wood type core layer

摘要

As legally required for sealing off sources of noise in industry, or as passive protection where work is carried out in noise-filled interiors, a sound-insulating hood or sound protective cubicle is assembled from structural elements. All these elements - such as walls, cover, doors, flaps, sound-insulators, and, if appropriate, floor, are in the form of composite panels (1) made of metal and wood-type material. These have a core layer (2) of the latter, and sheet metal layering (4,5) on both sides. The core can be of hard plywood, pref.beech, or chipboard, or hard fibre-board, with aluminium or steel plates cemented on.
