Sound Transmission Class. (STC) The sound-insulating property of an acoustic insulation board is expressed in terms of the sound transmission loss. (Stand alone soundboard insulation – no ceiling or wall assembly) ASTM E90-04, ASTM E413-04 STC = 15.
Noise Reduction Coefficient (NRC) A single number rating obtained by taking the arithmetic average of the absorption coefficients at specified frequencies, rounded to the nearest 0.05.
NRC = 0.50
Sound Absorption Average (SAA) A single number rating obtained by taking the arithmetic average of the one-third octave bands at specified frequencies, rounded to the nearest 0.01.
SAA = 0.49
