WebNoise reduction coefficient, or NRC, is a rating used to measure how effective a material is at absorbing sound. NRC ratings are calculated by taking the arithmetic averages of a material’s sound absorption coefficients at 250, 500, 1000, and 2000 Hz and then rounding it to the neared 0.05. Even though standard testing procedures will measure ...
