ABSTRACT:
A sound-barrier panel includes an acoustic layer that comprises chipped rubber and cord fiber from tires and a structural concrete layer bonded to the acoustic layer by a combination composite bond that includes both a mechanical portion and a chemical portion. The panel is formed in a special process that can define panels of various sizes, such as twelve feet by twenty-five feet in size. The panel has a high sound absorption capability and a high sound transmission loss, especially at low frequencies, and is extremely weather resistant and durable. The panel is also durable and cost effective and utilizes what otherwise would be potential hazardous waste.
