Sound Absorption is a technique where in various absorbent materials are strategically used to absorb sound to avoid unwanted reflected sound waves within a room or space. The main reason to use this technique is to reduce reverberation time (RT) for making the speech clearer. NRC (Noise Reduction Coefficient) term is majorly used within United State and defined as part of American Standards. The rating is unit-less and it is a coefficient and the ranges are from 0 to 1. Higher the average NRC is the better will be the absorption property of the product.
