Sorber Panel NRC ratings

The Noise Reduction Coeffecient (NRC) is a single-number index determined in a lab test and used for rating how absorptive a particular material is. This industry standard ranges from zero (perfectly reflective) to 1 (perfectly absorptive). It is simply the average of the mid-frequency sound absorption coefficients (250, 500, 1000 and 2000 Hertz) rounded to the nearest 5%.

frequency (Hz) 125 250 500 1,000 2,000 4,000 Overall
Noise Reduction Coefficient (NRC) 0.13 0.58 1.01 1.05 1.00 1.01 0.90
Based on the testing methodology, and depending upon the material's shape or surface area, some products can test at an NRC above 1.
