Auralex Studiofoam Wedge 1-Inch Acoustical Treatment Details Perfect for those environments that demand good sound control, but where complete acoustic absorption isn't required or desired. 1" Studiofoam Wedge works most effectively on mid and high frequency sound waves and may be used to acoustically treat walls or, most commonly ceilings (especially if they aren't parallel to the floor), even when the walls are treated with thicker acoustic Studiofoam. 1" acoustic Studiofoam Wedge absorbs as well as some competing 2" products, so if your budget is a bit "thin."
