A Noise Reduction Coefficient – commonly known as NRC – is a single number rating which represents the average of sound Absorption Coefficients of a material at specific mid-range frequencies (tested at 250, 500, 1,000, and 2,000 Hz octaves). The purpose of an NRC rating is to provide...
(2): Areas within buildings where the public is received, office areas, noise-sensitive areas, or locations with naturally low noise levels should incorporate measures to achieve a noise level reduction of 25 dBA during the design and construction processes. (3): Areas within buildings where the...

First, although there are more total mol- ecules in more the complex networks, each species is kept at comparable levels, and secondly, networks of equal total counts exhibit different noise reduction depending on their structure. Overall, the networks of biological origin exhibit better behavior ...
The amount of noise reduction can be quite significant; one can expect a reduction in the noise variance by a factor n. Of course, this is subject to inaccuracies in the model, e.g., if there is any change in the scene itself, or if there are any dependencies between the noise ...
