Acoustic Panel NRC ratings
The Noise Reduction Coefficient (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.
