Abstract:
1. A high frequency preserving, sound pressure standing wave reducing, acoustic room treatment panel, comprising the following elements; a. An enclosure having a frame comprising top, bottom and side pieces joined at the ends of the pieces to define a frame structure, b. A first layer of flat material with multiple through holes, of the same dimension, mounted within the frame structure, c. A second layer of flat material with multiple through holes of the same dimensions as used in the first layer, mounted within the frame structure located behind, and spaced more than ¼ inch apart from the first layer of flat material and aligned so that the through holes in the second layer of flat material are off-set, to the maximum amount possible, from the through holes in the first layer of flat material, d. A third layer of flat material with multiple through holes, of the same dimensions as used in the first layer and second layer, mounted within the frame structure located behind, and spaced more than ¼ inch apart from the second layer of flat material and aligned so that the through holes in the third layer of flat material are off-set, to the maximum amount possible, from the through holes in the second layer of flat material, such that the through holes in the third layer become re-aligned with the through holes in the first layer.
