X Y Z
Z-weighting: Z is for 'Zero' frequency weighting, but in reality 10 Hz to 20 kHz ±1.5 dB. Replaces the old Linear, LIN and Flat weightings, which were more confusing.
See other examples of Z-weighted information LZeq, LZF, LZS etc ., also written as dB(Z) and dBZ.
Zoom Analysis: can be used in certain situations to obtain a much finer resolution, over a limited portion of the total frequency range.
Zwicker Loudness: a technique developed by the late Prof. Dr. E. Zwicker for calculating a real-time estimate for the loudness of sound as perceived by the human ear.
