Z weighting

One of the standard frequency correction curves (or weightings) applied to sounds in a measurement device to simulate the hearing capability of the human hearing mechanism. The Z weighting is most often used for the measurement of octave band noise levels. The Z weighting response is specified in newer acoustic standards since it has a defined characteristic unlike the linear (or un-weighted) frequency weighting found in earlier noise meters.
