摘要
Structural elements exhibiting extraordinary soundproofing characteristics comprised of two rigid layers with an intermediate layer of resilient material integrated in composite unitary mass wherein the thickness of the layers, their modulii of elasticity and shear, as well as physical properties, are critically interrelated to impose sound-deadening effects therethrough. Such structural elements are especially effective when used as facings for insulating elements of fibrous, porous or cellular materials, especially where such are applied to the opposite side of the latter, in which case the resulting insulating assemblies present many advantageous features in the fields of building constructions and other industrial locales.
