When STC and SRC reveal how properly noise passes by way of distinctive supplies, NRC (Noise Reduction Coefficient) measures how properly supplies stop sound from reflecting (exactly how much sound they can absorb). The NRC is the percentage of sound that a floor absorbs (To paraphrase, hits a surface area and will not reflect again again in the place).
The first acoustic instrument was the human voice, which generates sound by funneling air throughout the vocal cords.
