About Percentiles
You can set up to five percentile levels (LN values).
Percentile level values are calculated for the total measurement. The percentile levels that you specify will tell you the
distribution of sound levels in your measurement. For example, if you set a percentile level of 90, the result is the sound
level that is exceeded for 90% of the measurement period.
