Weighting

Technology / Home Audio / Weighting: When laboratory measurements are taken of audio gear, the literal, 'true' figures obtained often do not reflect the anomalies introduced by human perception. In these cases, the measurements obtained may be mathematically modified, or 'weighted' to take into account the peculiarities of human hearing. A common example is 'A-weighting', a curve applied to sound pressure levels to more accurately reflect our loudness perception. Other types of weighting compensate for the ear's frequency response, distortion tolerance etc.
