A key benefit especially for an open office setting is noise reduction. Noise distraction is one of the top complaints from employees in workplace with open layouts. When scientists measure sound attenuation, they use “Noise Reduction Coefficients” (NRC) ratings, which range from 0 to 1. An NRC of 0 means that the product absorbs no sound. An NRC of 1 means that the product absorbs all sound. The higher the NRC, the better the product is at soaking up sound. Reindeer moss walls have been tested and found to have a NCR rating of .5, exceptionally efficient.
