Abstract
An acoustic structure includes a first, rigid panel (7), a second, rigid panel (11) aligned in spaced, substantially parallel, relationship with the first panel (7), a multiplicity of partition walls (15) running transverse to the panels of the panels (7, 11) and dividing the interior space of the enclosures into a single layer of cells (17) bounded at one face by the inside of the first panel (7) and bounded at the opposite face by the inside of the second panel (11), the partition walls (15) being bonded at the one face to the inside of the first panel (7) and at the opposite face to the inside of the second panel (11), and a multiplicity of apertures (19) in the partition walls (15) providing communication between adjacent cells of the single layer of cells (17).
