Hard surfaces such as tile floors, cinderblock walls and drywall ceilings typically reflect almost all of the sound that hits them. A common area [...]

NRC is short for Noise Reduction Coefficient.  In techno-speak, it is the average of the individual sound absorption coefficients of an item at [...]

Systems panels (cubicle walls) are getting lower or disappearing altogether in favor of the cleaner looking benching systems – groups of desks linked together next to each other and facing each other with no real space dividers between them.
