glass fiber requires support by hardware cloth, open-weave fabric, or expanded metal. For
  applications in which reflected mid/high-frequency sound from the panel absorber might create
  problems, a facing of glass-fiber board would not interfere with the low-frequency absorbing action
  if it was spaced to avoid damping of the vibration of the plywood panel. All room modes terminate in

  the corners of a room. A corner panel absorber could be used to control such modes.
