ACOUSTICAL PANELS
Solid wood panels have a relatively low Noise Reduction Coefficient and reflect most of the sound striking them. This often limits the use of wood in areas where noise reduction or speech privacy are important design issues. To improve the NRC of wood requires the creation of openings in the wood for sound waves to pass thru. When perforation are minimally 10% or greater an NRC rating of .75 - .80 can be achieved with sound absorbing materials. See Acoustics Learning Center on Ceilings Plus Web site (www.ceilingsplus.com) for more information about noise reduction.
1. Perforated panels: have become economical. The choice of percentage open and perforation patterns are many and affordable. See "Wood, Perforation and Soundtex Selector" on the following page.

Curved panels can be used to diffuse sound, eg, acoustical reflectors.
