Saa sound absorption

WebWhere NRC ratings consider sound absorption at four frequencies, SAA Ratings are an calculated using twelve one-third octave bands ranging between 200 and 2,500 Hz. These ratings are classified on a scale from 0 to 1, with 0 indicating no absorption and 1 indicating complete absorption. WebThe NRC value: Noise Reduction Coefficient (NRC) and Average Sound Absorption (SAA) The NRC value is an anglicism meaning “Noise Reduction Coefficient”. It is calculated according to the ASTM C423 standard. This NRC coefficient goes from 0 to 1 with : 0 indicates zero absorption 1 indicates perfect absorption
