http://www.panelfold.com/resources/testdata/ALLABOUTSOUND.pdf WebbThe NIC™ (Noise Isolation Chamber) is a patented technology that reduces high frequency power line noise. NICs™ use a non-reactive ferroelectric substance that actually absorbs high frequency noise. This reduces noise without any of the negatives associated with power filter coils, capacitors and transformers.

WebbNOISE REDUCTION COEFFICIENT (NRC) An arithmetic average of an acoustic material to the nearest multiple of 0.05 of four sound absorption coefficients at frequencies of 250 Hz, 500 Hz, 1000 Hz, and 2000 Hz. An NRC of 0 = perfect reflection and an NRC of 1 = perfect absorption. WebbNOISE ISOLATION CLASS (NIC): A single number rating of the degree of speech privacy achieved through the use of an acoustical ceiling and sound absorbing screens in an open office. NIC has been replaced by the Articulation Class (AC) rating method.
