weighting network[′wād·iŋ ‚net‚wərk]
One of three or more circuits in a sound-level meter designed to adjust its response; the A and B weighting networks provide responses approximating the 40- and 70-phon equal loudness contours, respectively, and the C weighting network provides a flat response up to 8000 hertz.

An electrical circuit that alters the sensitivity-vs-frequency characteristic of a sound level meter so as to improve the correlation between meter readings and the subjective judgment of noise by individuals. See the A-scale, which is the most widely used weighting network for measuring noise levels of equipment, in buildings, and in the community.
