摘要： A sound attenuation canopy for reducing levels of sound passing through an opening comprises a sound absorbing member. The sound absorbing member is comprised of a flexible sound absorbing material and has a first end, a second end and an intermediate portion extending between the first end and the second end. The first end is configured to attach to a periphery of the opening at a first location, the second end is configured to attach to a periphery of the opening at a second location and the intermediate portion is configured to be spaced apart from the opening. When the first end and the second end of the sound absorbing member are attached to the periphery of the opening, at least one side opening is at least partially defined by the intermediate portion and the perimeter of the opening, and a sound transmission flow path through open space between the opening and the side opening comprises at least one change of direction greater than 45 degrees.
