Beschreibung
Zusammenfassung:	construction engineering. SUBSTANCE: sound-insulating and heat-insulating material used for noise suppression in residential construction and industrial buildings is made in the form of multilayer foam foil base structure. High-density plastic materials in the form of loose material, mainly of granules, sawdust, small balls, etc, and in the form of metal sheet made of lead or annealed copper are used for the purpose. EFFECT: reduced energy of acoustic vibrations due to improved sound- insulation of any desired level. 6 cl, 2 dwg
