Sound absorption refers to the process by which materials reduce the intensity of sound waves. When sound waves hit a surface, some of their energy is absorbed, while the rest may be reflected or transmitted. Materials that are good at absorbing sound, like acoustic panels or carpets, help to minimize echoes and improve sound quality in a space. The effectiveness of sound absorption is measured by the noise reduction coefficient (NRC), which indicates how much sound is absorbed by a material. Higher NRC values mean better sound absorption. This property is important in various settings, including concert halls, recording studios, and even homes, to create a more pleasant auditory environment.
