Abstract
This invention concerns a sound-proofing panel, basically comprising a pair of layers (1) in the form of fibrous-material felts, such as glass wool, between which is a layer (2) which is considerably thinner, in the form of a plate, of a material with a high specific weight, made, for example, of plastomer polymers. This sound-proofing panel has high acoustic insulation properties, in addition to having a light weight per unit of area; it is also made of materials which are readily available and cheap (Fig. 1).
