ABSTRACT:
An acoustical wall panel has a core of a plurality of layers of glass fiber pressed together and having a density ranging from approximately two pounds per cubic foot at the front surface to approximately six pounds per cubic foot at the rear surface. A plurality of cavities are formed on the front surface of the core. The front of the panel is covered with fabric, and the rear is covered with a septum to provide a barrier to the transmission of sound pressure waves. The cross-sectional area, depth and spacing of the cavities are selected to improve absorption of sound in the intelligence range of speech while having less absorption in the lower frequency range to permit a desirable background or ambient noise to exist. The spacing and shape of the cavities also provides a smooth, continuously changing curvature in the cavity side walls to increase the surface area and enhance the capacity of the panel to absorb sound at flanking angles of incidence.
