Abstract : The patent relates to an acoustic barrier coated on one side of a wall to effectively attenuate and reflect acoustic energy impinging the wall's opposite side. Spraying or brushing on a layer of a semiliquid sound absorbing material and covering the sound absorbing material after it has solidified with a sprayed-on adhesive resin septum allows a complete continuous covering of a wall surface irrespective of its configuration. Thusly, rigid mounting devices which otherwise act as sound conduits are eliminated and by applying successive layers of the sound absorbing material and septums, a highly effective acoustic barrier is fabricated at minimal cost.
