The level from one of the time weightings (based on F or S), is sampled 10 times per second to
generate the statistical distribution function.
The dynamic range for statistics (going from 10 to 140 dB) is divided into 652 classes of 0.2dB class width.
During a measurement, each sample is put into one of the classes. After some seconds there are samples
enough to start looking at the distribution function of the sound level.
Up to eight percentiles (statistical values) may be shown numerically (and saved with the measurement).
The statistical distribution calculation applies to the spectral weighting networks (A, C and Z) as well
as all the individual filter bands (if applicable).
The complete statistical distribution values can be seen in a dedicated view called 'Ln'. Cursor buttons can be used to read out
both single class information and the statistical values.
