Abstract
A noise reduction barrier is formed by connecting together a plurality of prefabricated vertically oriented panel members so configured that a hollow tubular wall is formed between opposed panels. The space between panels is filled with sand or loose earth which provides the mass to make the structure sound retardant. In alternative embodiments, for increased sound absorption, perforated sheet material may be secured to the outer edges of the barrier wall and the interstices filled with rock wool or similar porous material.
Claims5
A noise reduction barrier comprising in combination, a plurality of vertically orientated tubular shell members, each of said shell members having one end thereof embedded in the ground and each said member joined along a vertical line to a corresponding adjacent member whereby all of said members form a contiguous linear array, and sufficient sound retardant material filling the space within and between the shells of said members to provide a mass of at least 4 pounds per square foot of exposed area, and means for retaining said material between said shells.
