TL;DR: A sound insulating sandwich panel is based on a rigid polystyrene foam core covered by thin layer(s) of mineral (e.g. gypsum) material as mentioned in this paper.
Abstract: Sound-insulating sandwich panel is based on a rigid polystyrene foam core covered by thin layer(s) of mineral (e.g. gypsum) material. The thickness of the layers and the elasticity modulus are so selected that the statically measurable structural rigidity of the panel should be between 0.2 and 1 kp/cm3. The pref. shape of the core is trapezoid, and the enclosed air space is pref. at least half of the total volume of the panel.
