sound weighting network

weighting network

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.
