A LAMINATED STEEL WITH AN IMPROVED CAPACITY FOR REDUCTION OF NOISE

Brief information is given on Steelacoustic sheet, a sandwich material consisting of a layer of thermoplastic between two sheets of steel and supplied in several overall thicknesses from 0.8 to 6.5 mm, normally in sheets 1,000 by 2,000 mm or 1,250 by 2,500 mm. It has been introduced by Noise Control International, who state that the material's noise transmission deadening properties are up to 900 times better than those of conventional steel sheet. The two steel facings, normally of electrogalvanised mild steel, need not be of the same material (e.g. one side can be work-hardening stainless steel, and the other side mild steel), and need not be of the same thickness. Steel acoustic sheet can be worked and joined much in the same way as ordinary steel sheet. It has an exceptional capacity for reducing both structure-borne and air-borne noise, and it is suitable for the production of any enclosure or structure for equipment whose noise must be minimised or contained. Mechanical properties are generally comparable with those of the two steel sheets laid loosely one on the other, without the thermoplastic layer, but fatigue properties are superior to those of ordinary steel sheet. Noise Control International is able to advise on the application of this new material. Order from BSRA as No. 52,075.
