A sound insulating barrier for improving acoustics in buildings, theaters, and around freeways, is disclosed. The sound insulating barrier has a multi-layer construction made of a layer of wood wool, a layer of basalt insulation material, a layer of sheet rock and a central core of basalt insulation material. These layers are repeated on the opposite side of the central core of basalt insulation to obtain a stand-alone wall. Alternatively, the layers up to the central basalt insulation layer can be attached to any pre-existing flat surface. The basalt insulation material is made of mineral wool. Conventional spacers can be used to separate layers or to improve the integrity of the wall. Furthermore, the sound insulating barrier can be built around conventional construction studs.
